P.S.: both mobos support ATX power supplies. Is it safe to use my 650W Corsair CS650M to test them?

Yeah you can.

Hopefully you didn't kill the board in question as a result.

Anyway, I only pulled that stuff with Asus, but they're both doing the same thing now

Maybe you missed my last reply on page 1, you really should be busy isolating the problem by basic troubleshooting and not try and rush your system into functioning, as rushing and hurrying to quickly fix stuff is a very good way to actually kill stuff (and lots of it).

Thanks for the advice. I'll start from scratch tonight 😀

So, I did just like Tetrium suggested. It worked when I tried the CPU the new motherboard came with. I tried this before and I'm not sure what I did differently this time, but it works now. Thanks, man! Thanks a lot!

My old (faster) CPU doesn't, though. So it's the CPU, although it did work before the whole thing.

Is there any way to know if the CPU is dead or there is something I can do? There is still no POST beep when I insert it.

The problem CPU is MMX 223. The working one is Pentium 120
