Random CPU Usage Spikes

post #1 of 6
Thread Starter 
Hey guys,

Recently I have noticed that my computer CPU will become unusually taxed while I'm doing normal tasks, although a fair few of them. Normally it will sit at 50% or below CPU usage, occasional jump to 70%. When I have these 'spikes' it's using somewhere between 80% to 100% of the CPU, and all I am doing is word processing, internet browsing and watching avi files on a second monitor.

Is this cause for concern? I think the CPU heatsink and thermal place is utterly shot, pulled everything apart a few months ago and the heatsink wouldn't come off the cpu...

I just want this to hold me over for another three to six months before building something new...

Anyway, are these random spikes in usage sign of bad things to come?

Unlikely, can you open task manager and tell us what processes are causing the spikes? You may also want to look at the windows 7 resource monitor as it usually shows a little more information than task manager alone.

It's not spiking now, but as I use it, I'll be sure to have a look. Last time I checked it seemed to be the System Idle Process, which I found incredibly bizarre.

But I'll be sure to check when it next occurs.

Would the length of time it's been running affect it at all? Normally happens late at night, when I've had it on all day...

thanks for the fast reply smile.gif

I've had this before, but hopefully it is different problems.

What happened to me was Java 32-bit (update 25) corrupted Windows, and refused to uninstall. This caused Windows to stop finding half my hardware, so I was down to a single core processor and less than 2GB of RAM.

Hopefully not ^that^.

ive had this problem too. the cpu usage peaks by just playing music using the onboard sound. and found out that it was a driver issue.

Thanks for the input guys, I'll look into it. Hasn't done it tonight, but I haven't been listening to music or watching videos, so drivers could be the culprit.
