What is Software Counterfeit Error of Windows Desktop

Windows BugWhat Is Software Counterfeit Error In DesktopWindows Bug Notification error









This error of a computer is one of the very headache, but most profitable work of the technician.

The very cause of this failure of the computer is using a pirated windows operating system most likely windows 7 and windows 8 of Microsoft.The security and settings under the user accounts of the control panel is open or what we called “auto update of Microsoft is on, “ not off”.That’s it, truly the technician after they installed the pirated windows software.They need to turn off the windows update after successfully installed the new operating system.Why?because the user know how this error will happen.They click ok the balloon tips when the Microsoft say “Update your windows” once the computer is connected to the internet.

No wrong in the haft of the Microsoft regarding with this failure.We called this bug of the windows,because instead of the add- on for the Operating system, like the full security of the user once on the internet become a “bomb of bug”.I define windows computer bug as “Inconvenience to the user once it is infected with this failure of windows desktop.This is a truly notifications that we are a “victims of software counterfeit” or our use operating system is not genuine copy of operating system.As I said, no wrong with the Microsoft in other side.They made the auto update for our own goodness in using their product.Most particularly the safety of the user once they enter in the International Network of the computer.Sir Bill Gates own this windows operating system and it’s intellectual rights property.
  • Why this is happen?
This is a key role with regards to the computer technologies and the user itself.The trend of the new technologies that we have.Because user or our generations became knowledgeable.When they know the high price of one windows 7 or 8 CD/DVD installer, they said “high price”,most particularly in Asia that windows piracy is rampant.They bought the computer assembled with no operating system.Now, they will find a pirated windows installer outside or to the outside sources.Now they installed the windows as package until it ready for use for our files and internet ready.
  • What are the scope of work of the technicians and why is it very high price of the professional service fee?
The scope of work by the technician is also high or more hours of work. If the computer can't boot to desktop because of this error, the service men will trouble first the boot start or the start up of the computer windows operating system. Once the startup files are operable, then the computer will boot to desktop. The technician will start also for a checkup and backup the important files of the user or the client. This is the very risky and very responsible of the technician, the important files of the client or user. Now when the backup is successfully performed.They will start to check the programs of the computer, what are installed and use program of the user. That’s why “package” because the installation of windows operating system to programs, such as driver software and Microsoft Office 2007 or 2010, etc.


Now during the installation of windows the technician will probably encountered the trouble or error of the hard disk drive.Such as what you see of the picture here.Now the technician will find an answer to this problem.They will find a source such as a program how to remove this failure.Because this is an error of the software the “OS”.

The technician cannot change the hardware, the storage media as the stationary drive of the operating system.If the hardware change by the technician, surely the user will angry, because they will loose money for budget of the HDD and most particularly also the important files will vanished.And also the HDD itself have no physical damage to the part of the circuit and controlling IC’s.

If the technician will find a something a program to debug this error,its better because the windows will recover using the program.All the program settings and files are accessible and the black screen of the desktop became stable.And the notification of software counterfeit above the notification area of the desktop taskbar will vanished.And you can set now your windows desktop background and your desktop tools and all the programs are accessible.Now the technicians will install the new virus scanner for this.Because,surely the virus scanner is also verified.After they installed the virus scanner,it will perform the updates for virus definitions.It’s an idea of the technician or a decision of the owner to buy a new license virus scanner. And now last the virus scanning of the computer storage media, the drive of the computer, the drive C: as the operating system and the drive D: as backup drive.Now you will pay as much as 1,500 pesos in Philippine money to the computer technician, “Package Price”.
  • Advantages using a license Microsoft Windows Operating system
hassle free and no headache when Microsoft conduct inspection of the user in every country.Most particularly to the business establishments and supplier of the computers which installed the Windows OS.
In terms of the use of the windows, particularly in using the internet through the browsers are more reliable and feel free the service of the Microsoft in internet.Such as full security of the your computer and us or you whenever hackers and crackers will attack.Also updates for the support of the programs.Most especially the updates of the drivers of the hardware or devices of our computer.Both input and external hardwares or devices.And service for the emails and such away the service of the sky drive using the MS-Office online or of the internet.
  • Disadvantages using a non- license or not genuine Microsoft Windows Operating System
Very hassle and foot to headache when Microsoft conduct inspection to the user in every country.Most particularly to the business establishments and supplier of the computers which installed the Windows OS.And may the subject for seizure and all of our computer that installed not genuine windows.

In terms of using the program or running in internet is very hassle.It’s easily hack or crack and easy to bomb any type of viruses(Vital Information Resource Under Seize).The virtual memory will easily full and very time consuming and may the budget for the repair of the windows is always rising.Lack of the support of programs and hardware’s driver software.And no security of our files, it’s prone to damage or corrupted files.May cause of dumping of memory and Blue Screen of Death of Computer(BSOD).And subject for software counterfeit error during windows update.You cannot use the Internet Explorer of the Microsoft and sky drive application of the internet.You cannot update the Windows Media Player for the different codec's for multimedia application or our movie files.

    The Best of Pilipino’s “Electronic Charcoal Kalan”

    Electronic Charcoal Kalan Actual View Electronic Charcoal Kalan Power Supply
    Now a days the word budget is always on the mind of every Filipinos, particularly among us in middle class families.We always think income wise and low budget for our daily needs.That’s include our rice,dishes,clothing,shelter,lights,and for cooking use.Using a gas stove or gas burner like Gasul etc. is not budget wise because of its high price.And also using an electrical cooking device is not advisable because it will add a high kilowatt of electric bills that can kick to add our high payment bills in every month.That’s so very headache and can empty our poor pockets.

    Times came Pilipino use a wise skills that to invent a cooking device that uses a Charcoal(“Uling in Pilipino Dialect”).Actually,the coconut charcoal is an old use from our ancestor for cooking rather than using a piece of cut body tree or branches.But the problem is, “we always use our mouth to blow the fire so that it will constantly producing fire to the cooking ware”.That’s so tired able work and responsibilities in our house to serve our food daily.

    So, we got the answer for our problem.Because of computer we find ideas using the exhaust fan of our broken computer power supply.Me,I’m benefitted for my design,as a computer technician I have plenty of broken computer power supply.I use to recycle it by using it in other purpose.Now another problem is the electronic power supply to drive out the 12 volts direct current to maintain the rpm(revolution per minute).For blowing the charcoal to produce a constant fire inside the Charcoal kalan.And using the unused PVC pipe from our neighbor carpenter.I used it for the air tube to maintain the air velocity came from the two exhaust fan.

    Now, I got the solution for power supply of the charcoal kalan.I remembered during the TESDA assessment of Electronic NC2.The Consumer Electronic Servicing NC II.They are assembling a 5 volts and 12 volts power supply using the output IC LM 7812 and LM 7805. So, as I’m also a electronic technician I tried to assemble the 12 volts output power supply.And I got a perfect output voltage,I just tried it to connect the two binding red wire and two binding black wire as Positive and negative 12 volts.Now its just a perfect,its blown a perfect velocity of air through the PVC pipe as my air tube to the kalan.

    Imagine!of 1 ballot of coconut charcoal worth of 5 pesos we can boiled 1 liter of water,and we can cooked rice and dishes.So this is it the answer of our budget for cooking purposed.Not only coconut charcoal that we can use of this electronic cooking device but we use any piece of wood scattered around or as a garbage wood.Its also way of recycling the garbage found in our surroundings that could be use in other purpose.And can help and relieve our budget for our daily needs.

    So,that’s it I inform and relate to you the best of Filipino’s Electronic Charcoal Kalan.This could help to elevate the budget of using any gas burner or electrical cooking device.But this unit cannot be use inside our house kitchen this is only for outdoor dirty kitchen.

    That’s all and follow this blog always, next post of my electronic I will publish how to build this project, Electronic Charcoal Kalan”. And good luck and God Bless to all…

    What is IC Creep of Computer and What are Possible Solutions

    IC CREEP OF COMPUTER PCIC creep or what we called chip creep of computer was a  problem refers to integrated circuit(IC or Chip) of early computer before. As I encountered before with the early processor of the Intel, like Pentium I 166 MHz.That was loose up its way on the socket and it was cause a failure of the computer system memory. Chip creep also occurs when the chip is poorly supplied with a cooling system and a dust buildup much inside the system unit.That will cause failure of the display of the computer during its processing.An a chip corrosion may build its way in the pin of the IC.And possibly your operating system cause a problem of Blue screen of death(BSOD).

    This problem is an issue of the early computer. But the other problem that I was encountered is also a problem of the computer that we have now in this generation.From Pentium III down to core2duo, but when we said due to its retainer clip and cooling system. It just 50/50 percent due its tightly retainer clip and improve cooling system.

    This problem of the computer may occur also in your new computer.If dust build up held up in your computer air block type cooling system.And that will cause down the revolution per minute(RPM)of your cooling system. May heats up the IC of your computer motherboard and most especially to the main chips.The Southbridge,Northbridge and the main chips(Processor Chip).

    Now what's the main purpose of this post.This is not only a pointers for the exam of NC2.But of course to equip you with the information that I was encountered in my PC repair.And my experience of my 21 units PC,they are Pentium 1,2,3,4.Now we have words lubrication and isolation.This is a part of maintain,diagnose and troubleshoot computer systems.The word lubrication is a word refer to the maintenance of the cooling fan and exhaust fan(air block).But if your computer have a thermal and water block cooling system much better.But you need also to gather info how to maintain this cooling system.And the word isolation refer to the disassemble of PC and testing the memory,MOBO,and VGA using the other one good CPU(system unit).

    PARTS OF THE COMPUTER SYSTEM THAT HAVE AN AIRBLOCK COOLING SYSTEM:
    • POWER SUPPLY UNIT(P.S.U.)
    • PROCESSOR COOLING SYSTEM(AIR BLOCK)
    • REAR PANEL EXHAUST FAN(SYSTEM UNIT)
    • SIDE COVER OF THE SYSTEM UNIT
    • FRONT PANEL
    TOOLS WE NEED AND GREASE:
    1. Mechanical grease(use to smooth the thick part of thin ball baring inside the shafting.So that it can rotate freely and smoothly)  
    2. WD40 or mechanical oil(use to remove a thick dust and stain or corrosion)
    3. CUTTER blade(use to remove a thin rubber ball cap of the cooling fan or exhaust fan)
    4. Paint Brush(use to remove dust)
    5. Pencil eraser(Use to clean contact pin)
    6. Thermal paste(use to tighten the processor and heatsink)
    7. Screw driver
    8. Multi tester(VOM)(Voltage and resistance testing)
    9. Paper clip(Use for jumper or grounding pin of PS_On)
    These are the procedures:
    (Apply the safety precautions before to handle any parts of the computer hardware)
    1. Open the system unit
    2. Remove the hardwares(be careful and observe the correct orientation of the connectors)
    3. Remove and isolate the PSU
    4. Unscrews the four screws of the cover
    5. Unscrews the four screws of the exhaust fan
    6. Once you isolated the Fan,use the cutter blade to remove the thin rubber ballcap(remove first the sticker)
    7. Once the ballcap has been remove,use the mechanical oil or wd40 to remove the corrosion that will block the rotation of the fan
    8. Put the mechanical grease inside the shafting hole
    9. Then cover the shafting hole(return the rubber ballcap)
    10. Now,assemble the fan in the power supply case
    11. If dust buildup held up inside the PSU board remove it first using the paint brush
    12. Now use your visual inspection of the electronic parts(check if there are no leakage,locally called by the technicians “pregnant caps” of the capacitors locally position in the output part of the PSU board.If happen there are pregnant caps replace it.
    13. Now,proceed for PSU testing.Insert the power cord in main socket of the PSU
    14. Now find the green and black wire(PS_on wire)
    15. Use a paper clip to jumper the two wires
    16. Now once the fan rotate smoothly,use your VOM tester to measure the correct voltage of the PSU output
    17. Now proceed for MOBO isolation and testing,get a foam or any rubber mat.Put the motherboard above.(be sure that you clean first the MOBO,RAM,and VGA).Use the pencil eraser to clean the contact pin of RAM and VGA
    18. Connect the power supply,RAM,Processor(use the thermal paste to tighten the processor and heatsink of airblock),and install the VGA(tightly clip the retainer clip)
    19. Connect the Keyboard
    20. Now, power up for testing,find the PS_On switch of the F-panel header pins
    21. Use your flat screw and ground the two pins
    22. Once the processor cooling fan rotate freely,press the number lock(NumLock) key of your keyboard
    23. Once the number lock(NumLock)key light indicator is on and off mode your testing is successful and the CPU surely will display in monitor screen.
    24. Now assemble your clean system Unit(CPU)   
    If happen there are no display:

    Indication and symptom cause by overheating parts may a problem of IC creep. “Power light is on nothing on the screen,no beef codes,unstable rotation of CPU chip cooling fan even the PSU output voltage is normal,and numlock key light indicator of the keyboard flashes once power on.
    Possible cause overheated parts of MOBO main chips may a problem of IC creep.Technicians not to throw or say “unused MOBO”,use the techniques of trial and error and last/final resorts.
    1. Assuming you perform the above procedure, but nothing happens
    2. Remove all the removable parts of the MOBO,such as RAM,Heat sinks,BIOS battery,CMOS chip,Processor
    3. Use a running water,and use paint brush to wash the entire MOBO parts.If available use powder soft to remove the stain and possible pin moisture of the MOBO chips(Note:if your MOBO is a pin less processor,be sure not to brush the socket pin of the MOBO.Its a very tangible pin may cause to dislocated and cannot be return in normal position) 
    4. Lay down the MOBO in a wall,take time to drain the water absorb in MOBO
    5. If you see that its dried,now use a hair blower(hot air)and heat the MOBO by rounding the blower(Hot air).Be sure to blow the hole of the ports(I/O) and the sockets.(Note:estimate the heating property of the MOBO by touching the MOBO parts,if you sense that you cannot hold the temp. stop the hair blower)
    6. Now proceed for trial and error technique.Assemble the MOBO parts including the processor.Be sure the correct orientation of the connection including the MOBO sockets, bus wires and cables.And connect the PSU in MOBO atx power connector.
    7. Connect the keyboard
    8. Now use your screw driver,find the PS_ON pin of the Front panel connector of MOBO and ground the two pin.
    9. If the cooling fan is rotate normally the power is okay
    10. Now press the number lock(NumLock key)of your keyboard
    11. If the NumLock light indicator in present,press again the NumLock.Once its off and on mode your MOBO now is going back normal and have display once you connect your monitor screen.
    12. Now assemble your PC and back to service.

    TIPS!


    • Repeat the procedure again if nothing happens,use the procedure of resetting the CMOS/BIOS IC using the RTC jumper that I was posted in MOBO parts and function under the CMOS.
    • If the MOBO is not recover normally replace now the MOBO.Do not throw the damage MOBO you can use the electrolytic caps to replace the pregnant caps as I said above of this post.  
    • Performing this procedure only for qualified and train computer technician and have a knowledge of voltage testing and resistance.
