I've had my Dell Inspiron 9100 for 6 years. It's worked very well for me till recently. Now, for no obvious reason, the computer will freeze in the middle of whatever I'm doing, be it video capture, running Quicken, surfing the web, etc. The cursor freezes on the page and no keys work. The only solution is to hold the power button till the computer shuts off and then reboot. I've cleaned the fans and their filters. I've run the exhaustive Dell Diagnostics program (no problems found). I've even downloaded a fan control program that supposedly keeps my computer running a bit cooler (which it seems to do, but it still locks up occasionally). Oh, btw, WinXP Pro (SP3) is the operating system.
Could anyone please tell me what the problem probably is and how to fix it?!?!
Thanks in advance!
