Dell Precision 690 running XP Pro. This doesn’t happen all the time, but seems to occur when I’m on the Internet. When I go to CTRL + ALT + DEL or flag L to lock my machine, I get a quick blue screen and it crashes. Sometimes it takes a few tries to get it to stop crashing after it has the first time. I’ve done a little research and most point to RAID configuration in the BIOS as the problem, but I have checked that and it’s fine. My company’s IT department is full of fail and I’m no longer doing IT myself, but I would love to fine a solution so I can get some actual work done. Any help is greatly appreciated. Thanks!
