Computer freezing lately
I just built a computer, with fairly new parts, and it was running smoothly until very recently - now I can't use it for very long without it freezing!!! When I hard reboot, it either doesn't output to the monitor or it freezes at the point where it would usually boot from the hard drive, displaying a bunch of J's on the screen or beeping continuously until I turn it off. I have to shut it off for several minutes to get it to boot up again, but I'm afraid to use it for very long.
I think the issue is related to overheating, possibly my CPU (I really hope so, because I intend to replace it very soon anyway). CPU usage was at 100% when it last froze (according to Gnome System Monitor). The motherboard is an Asus P5B-E (LGA-775, 533/800/1066 FSB). I'm using a Celery 2.93 GHz CPU - 512k L2 cache, 533 FSB. The RAM is supposed to be 800 MHz, but I think it's only running it at 533.
