Ok so i have an AMD Athlon XP 1600+ Cpu, I went into bios and chnaged the clock frequency from 133/133 to 160/133 and then i saved to cmos. Right after that the computer wont post. The fans turn on and the lights but no beeps and nothing to confirm posting. I tried removing the cmos battery twice and left it for a good 7 minutes and same problem. I have the same mobo as a spare should i replace it or is the cpu completly fried? I didnt smell anything tho.
