This one's really got me baffled. In any given session on my laptop, I can load pretty much any installed program, no problem. BUT, if I exit a system intensive program and load another one, either the same program a second time or a different one, the computer crashes on load. Always before the program starts, always with a black screen and that "in progress" blue ring- which is frozen. I am unable to alt tab, ctrl alt del, or windows button out of it. Only a hard reset/reboot clears whatever the problem is. This is consistent across many programs, usually games. At first I'd thought it was a particular game, then I thought it was Steam games, and I've eventually figured out it's a system wide problem. I've had this hard drive set up for a couple of years, and there was a definite time a few months ago when this problem started. Never had it before, always have it now. I'd suppose this would mean it's something software related, but I have NO idea what. I guess if I have to, it might be time to slick my hard drive and start over, but I'd really rather not do that unless I have to. Has anyone else out there run across anything like this?
