I have a Dell Inspiron 9400 laptop, Vista Home Basic.

Yesterday, this problem just started happening. I booted up, everything was fine for about 5 minutes, then all of a sudden I noticed my fan became obnoxiously loud. In addition, my laptop became extremely unresponsive and slow, so I opened Task Manager and saw my CPU was at 100%. I immediately shut down, waited 10 minutes, and rebooted only to have the same thing happen again, but it took a little longer than 5 minutes for it to lock up and stay at 100%. If I just let it sit there for a minute, the CPU percentage would go back down to between 30 and 50% and the fan would stay extremely loud. But as soon as I clicked ANYTHING, it'd go back to 100% and stay there as long as I was doing anything.

I've scanned it with AVG, AVG Anti-Spyware, and Ad-Aware and none have come up with anything.

From what I saw on the processes list in the task manager, svchost.exe seems to be the biggest contributor to it slowing down. There are a few others (PCMServices.exe) that seemed to bog it down, but I know this process has a history of bogging down CPUs.

What can I do to fix this? I've googled it and come up with dozens of different solutions, but all of them seem to pertain to an XP system..

Thanks.

Hey, the same thing started today on my comp.
Hope you'll find out what's happening there.
But for me, it's my PC, not a laptop.

Hi aces :)

For the svchost file, right click it and select "go to service(s)". This will tell you what service is using that specific instance of the file.

All you can really do is identify what programs/services are hogging your cpu, then make sure they are running correctly. Once you know what is doing it and if its running properly (no errors etc) then you should pick and choose what you want running and close the others if they aren't needed.
