I went from an Asus P4C800E-Delux to an Intel 865Perl. When I updated the bios to the lastest available on Intel's web site the system refused to shut down and would just reboot! Any way I brought the board back and they exchanged it for me and now the system works great again. Much more stable than the asus, beleive it or not. Anyway my question is, has any one heard of this before? Being the hardware junkie that I am, it's a real fight not to upgrade this board. And that's no joke, I think this time they'll tell me to cram if if I bring this one back with the same problem.
