I recently got two old Abit boards from dumpsters finds, they worked in the first time, but later, now doesn't POST without beeps and it's POST code screen gets stuck in 9.0, if i try to restart using the reset buttong, it gets stuck in F.0, i've tried multiple CPUs, RAMs, PSUs, videocards with no luck at all, it doesn't even beep without RAM or videocard and gets stuck at 9.0.

Do anyone knows about the issue?

I've looked across on the internet, but nothing helped
