Hello Fatie32...

I looked through your topic with essexboy and agree that you have a hardware issue with the CPU. At this point, it's pretty tough to tell just what IS causing the problem, but it could be:
  • The CPU fan is not running or is not running correctly.
  • The CPU cooler is clogged with dust.
  • The thermal bond between the CPU and CPU cooler has been broken.
  • The CPU capacitors are failing or have failed. (Images of bad caps)
Look at the capacitors that sit nearest the CPU. If the tops or sides are bulging or they appear to have been leaking, that is likely the problem.

Look at the CPU cooler. If it is full of dust and fluff, cleaning it using canned air may help the problem.

Look at the CPU fan with the machine running. Does it run steadily and at a fairly rapid rate?

The caps look good, though the CPU cooler looks pretty dusty.

The clip that holds the CPU cooler on should have a sleeve thing on one side that you can fit a regular screwdriver tip into...probably the side with the least clearance near the power supply. Use a screwdriver to push down and out slightly (towards the power supply) and it should release the cooler from the socket.

Work carefully and be sure to touch a metal part of the case to discharge any static before rummaging around in there too much.

Somebody got it on there... :P

Would it help to remove the fan from the cooler? Just the four cross point screws hold it in place.

Just a bit of help if I may. Are you pushing down on the clip before trying to pull it out?
Most of the older type clips are shaped like a hook so the metal piece needs to be pushed down and out to release.

Yep that is normal for that type of clamping system. I always used a small pair of needle nose pliers to pull down and out. That way I could get enough grip without breaking it.

Go from the side and right above the opening in the metal clip where it bends back. That should give you enough to force it down and then out to clear the plastic clip.

Good job! (thanks Ron)

Now you just need to clean all the old thermal compound off both the cooler and the processor being careful not to scratch either of the mating surfaces. When reapplying the compound, don't use too much...you really need just a very thin layer on the processor.

You really should consider getting a can of air to clean the CPU cooler a little better...and really use it on the power supply. In the picture it looks like it's plumb full of fluff. It needs to breath, too.
