I just got a new ASUS motherboard, the A7V880, and have had problems with everything freezing up (requiring a reboot) since then. I also put a new XFX 6600GT on it. I have a Athlon XP 3000+ processor with a 400W power supply, and the ASUS Probe I have says that all of the temperatures are fine (usually below 50C). I have tried multiple video drivers (finally sticking with the newest ones that work; the absolute newest ones had some visual problems), installed the newest BIOS files, switched the sound card out for onboard sound and back, and tested the memory, and everything still acts the same. The problem itself, as I mentioned, is almost random freezing. I say almost because in Windows it's fairly random, anywhere from 30 minutes to a few hours between freezups (usually a few hours). In most games, it's the same. However, in World of Warcraft, it usually freezes up in less than 10 minutes. Also, the system freezes up almost any time I quit a game, and often when I Ctrl-Esc. Any ideas? After I post this, I will be switching mice to see if that's it, and then changing video cards to my old one... If neither of these work, I'm starting to run out of ideas...
