|The CPU usage is at 100% on my sony laptop, but fluctuates after awhile. One of the svchost.exe processes is taking up over 160,000k. Start up takes between five minutes and a half hour. White and black screens appear and stay for many minutes at a time. |
This started a few days ago, when I had run a disk defrag and ran a registry cleaner with Speedupmypc. I deleted the program, in case it was making things worse.
I have tried a clean boot and many other things.
I have also downloaded process explorer, hoping to root out the service that is responsible for the high CPU usage. Svchost.exe is definitely the highest, at over 160,000k, but there are so many services linked to it. I don't know how to figure out which is making it bad.
