I'm having a problem, I seem to be getting this problem where every now and then, my CPU goes up and down, even when I'm not using it, and it creates this big massive lag. It will go from say 0% to 8% to 41% on the taskmanager, then back to 0, back up, etc, you get the idea. Anyway, I'm sure it's a virus of some kind, but then I've got up to date purchased copy of McAfee, and Spybot, which reveal nothing, I've also used HiJackThis to see if I can find anything, and I don't think there is any problems there, although I can't really tell if all of those things could be disguises. Anyway, what do you think it could be? It hasn't happened for 12 hours at least, then just 10 minutes ago, it happened for a while, and then it went away after 5 minutes. It only started happening two days ago..

What process is chewing up all the CPU time? It might just be easiest to reinstall the OS fresh.

Nobody had the heart to reply then? 
System Idle Process is supposed to take up the CPU 'usage' when nothing else is... it means the CPU is idle. When System Idle Process is lower than 99% it means the CPU is doing something.

I have the EXACT same problem. I've just posted a thread on it and now have seen yours. My thread -> http://forums.overclockers.co.uk/showthread.php?t=17660898
It also started to happen to me only two days ago
Weird eh? Dunno what's causing it.

The System Idle Process should be using 99% most of the time, that's just showing what's left out of 100. What you need to do is find out what process is using the CPU when the total load goes up to 40%.zaza said:
I've got rid of the spyware now and the problem still occurs. He doesn't actually say which process it is that's causing the problem so how do you know it's not the same thing? I'm just making an assumption on the fact that we have very similar symptoms.ns400r said:

I think the OP is referring to "System Idle Process" which is the idle state the pc sits in when it's not doing anything.. so System Idle Process running at 99% means it is 99% idlemark1 said:
Looking at your thread, you have a different problem (no idea what though).As has been said, system idle process is meant to use up cpu time when no other apps are using it. System idle process is on 99% most of the time for me as well. So it's obviously a different process that's causing it for the op, like it is for me.
Dear me no, the system idle process should never go above zero.rpstewart said:
