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.
