PC Shuts Down

  [email protected]© 15:16 03 Aug 2008

My PC keeps turning itself off and restarting. It seems to do it when its been on a while or when I am multitasking. Maybe the CPU is faulty and getting too hot. All fans are ok and vents vclear. How do I find out what exactly is at fault?

It does suggest overheating. Have you cleared the accumulated dust and grime from the fins of the heatsink(s) and from all the fan blades?

I have installed Speed Fan. What now!!

watch the temperatures when you are multitasking, do they go high?

What is high? The core says 44 degrees I guess that is CPU.

I am still not nearer as to finding out what the fault is. Any more ideas please?

44 should be ok. But as above I will go along with Heat. Try taking the Side of the computer as During hot weather it can build up. I run my main comp with both sides off, about the last two years

While removing the sides may help it will also reduce the efficiency of your fans. The sides are required to be on so that the fans can draw air over your motherboard and components.

I would agree this seems like an overheating problem. keep the temp monitor on for a while and check or variations on temp, cpu is not the only thing that can overheat. The hd and motherboard are also prone to this.

Well my heat was building up in hot weather before, it doesn’t now

I wasn't implying removing the sides wouldn't work. I have done it myself on an old computer, but found adding another case fan worked better.
