I have windows XP with SP2. My computer crashed several months ago. I used the recovery CD's to reformatt the entire computer which usually works perfectly. This time however, my computer keeps saying my CPU usage is a constant 100%. I know this can't be right. It' does run a bit slower than it used to. Is there some way I can find out what's causing my computer to register the CPU this way and is there some way I can clean it up some?
Thanks a bunch!

This sounds like a virus. Hold ctrl, alt, delete at the same time and have task manager come up. Switch to the process tab and look through whats using up the most CPU.

One time this happened to me and my computer was going terribly slow. It always said 99-100% cpu usage and it was under system idle processor. That shouldn't really be using any. Turns out I had a terrible virus.

I looked under the processes and it says that spoolsv.exe is using all the CPU. If it's a virus, how would that show up in a clean reformated computer that had no access to the internet at all?

Well I just googled your problem, and the spoolsv.exe is from you printer. Maybe this article can help you out: http://torque.oncloud8.com/archives/000384.html . If something is confusing I might be able to help you out.

Thanks Sterling! It's amazing sometimes how a simple little fix can make all the difference in the world when it comes to your computer speed! I won't know if the fix is permanent until I reboot, but it sure beats what I was working with!

Could be a backdoor.
Check the startup list -

Recheck the spelling of that .exe.
Run a virus scan.
Have a look in here -

As far as I can make out.

Good luck. :thumbsup:

how would that show up in a clean reformated computer that had no access to the internet at all?


Just like to add, that considering this I agree it should be hightly unlikely, so no need to panic.
Anyways better safe than sorry. I couldn't see it as a backdoor, but virus do spread through other means than the internet.

System Idle Processes should be high when the CPU is not busy. When Sys Idle is at 100%, CPU usage is 0%. http://www.processlibrary.com/directory/fi...20process/25540

RknRusty is correct. 100% SYstem Idle = 0 load on the CPU. The system is free. Open an application and see the change.

Oh, I didn't know that. I assumed it was since my computer was going so slow, and task manager said 99-100%. My total CPU usage said 100% though at the bottom of task manager, and nothing else was using it. It's no big deal though, since its not a problem now.

Congratulations on your fix G Eris!
