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..
