Is this still related to your Windows XP SP2 computer? It helps if you give computer info in each post...
Your previous post mentioned "lots" of screensavers. Have you tried disabling your screensaver altogether and running without one? Just to see if it makes a difference?
Start troubleshooting by doing a little computer clean up using the instructions in the links below:

Then run Error Checking/Chkdsk using this link:

Hope this helps and let us know how it goes.
When I bring up task manager and click on a process to select it, it constantly flickers. This has been happening for about a month. Also explorer.exe has been using lots of cpu's when accesing folders and files making it very slow opening. Occasionally a low grinding noise on computer. Run norton, adaware, spybot, no viruses. Have spysweeper program. Finds no viruses. Any suggestions and help is appreciated.
