My K7T Pro2-A wouldn't go past the post. I've tried my T-Bird 800, 1000, Duron 650, they all failed. It froze usually after posting the CPU speed or after detecting the HDD. There were a couple of time I was able to get to the BIOS, but a few seconds there, and it froze again. I tried clearing CMOS, no luck there. I thought it might be the Antex P303 300W power supply, but I just replace it with Sparkle's 300W, same problem. Please Help, I've been tweaking this Pc for two days and one my 800 T-Bird don't post no more; I think it's fried?.
