PC Help - CPU Running At 100%

Recommended Posts

Just wondered if any techie peeps had any idea:

In the last week or so, my PC has been going a bit mad. I have a windows sidebar, which displays the PCU % and RAM etc. The CPU is sometimes running at 100%, mainly when I have firefox open, and iTunes is another thing that seems to kill it.

I can hear the fans cut in and go beserk too.

I've tried a system restor, but it hasn't worked. I've done all manner of Virus scans, spyware scans and malware/adware scans. Nothing found. I've cleaned/defrag'd the registry (which it said should improve performance by 6%!) but it's still running too high.

Anyone know what the problem might be, and what else might you suggest?

If there's any more info I can post up to make diagnosis easier I'll be more than happy! (Task manager screenshot for example).

Ta muchly if anyone can help :)

A screen shot of task manager would be helpful so we can see what the big applications are that you have running.

I was wondering where to post it. Completely forgot about Help Me. Some Mod I am.

I'll kick the kids off the PC (on my phone at the mo) and get this info posted. Thanks for your help guys. I was close to throwing the PC through a window last night :)

Ok, first off I did the wrong one which was "Re-Image". This did a scan and said I have stability issues (no jokes please, I know I'm insane - it's the PC's fault!).

My system stability is 63%

Then I did the SIW (hope this is what you're after):

This is a screenshot of task manager as of last night, when I had the problems:

One other thing which may help - this only seems to happen in the evenings. The PC is on all day (from about 8am) and by 7pm the CPU is regularly going up to 100%, and then I have freezing and crashing (programs, not the whole PC)

Pop the side off and hoover the fluff out.

I can't pop the side off! It's all riveted!

I have hoovered all around though - fans, vents etc. It was still behaving badly afterwards.

your not running extremely hot. at the moment.. although your comment about not being able to pop the side off is confusing as i have never ever seen a computer you cant get to the internals... you sure there isnt a latch on top or anything?

leave SIW running and see what the temp peaks at later.

it does sound like you have a temp issue though

I'll have a look again later, but all I could see last night were rivets all the way round. The only screws were the ones which hold the fan unit inside.

It's an HP Pavillion.

if there are no screws there will be a latch/ lever possibly on the top of the tower

going off this image there is a latch at the top on the rear image, you should be able to pop a side off especially on a HP!

Do not what ever you do, hoover the inside of your computer, unless you are using a specialist conductive hoover with grounding straps. It's a sure way to kill a computer due to the extremely high levels of static electricity generated.

Another effective way is to just blow out all the dust using your mouth.:)

That's exactly the same as the back of mine (but when I saw the rivets I stopped looking!) I'll have to have another look later then.

I hoovered my last PC (now upstairs in the kids room, working fine) several times, including taking the fans out and hoovering them seperately. I was told before it's risky, but that was a last resort too. If I can't solve this by any other means I might have no choice. Otherwise I'll go insane.
