Okay I just got a K7S5A today due to the fact that my previous motherboard crapped out (wasnt able to boot at all and prior to that I had spontaneous resets and i had to clock my chip down just to be able to boot.) Anyway, I installed everything in, hooked up the power and started her up. It turned on, I saw the BIOS screen for about 2 seconds then it "shut down" (LEDs were still on and the HSF was still spinning but all I had was a black screen). My first reaction was that I burned my cpu or something drastic like that, so i took off my heatsink to check it out and it was okay, so I carefully reattached the HSF. I made sure everything was connected properly. Anybody have any ideas?? Oh, btw I have a 1.33 GhZ t-bird but when the BIOS screen was up for its whole 2 seconds it showed that my chip was a 1000MhZ!!! IM STUMPED, PLEASE HELP ME!!!
