I have an a7v mobo and at about 2 or so did some o'cing. My pc didn't boot up again after I set it at 133 cpu bus. After resetting cmos and bunch of other stuff figured my processor was burned up(duron 700). Just now I held in the power button for like 30 seconds and it booted back up in safe mode and all it good. I was already considering buying a 1.2gig t-bird but now will keep duron til the thunderbird is aboutr $70 or so. Thanks for reading!
