Bought a used CPU / Motherboard bundle on ebay. It's a 939 4400+ X2 with an MSI RX480 based micro ATX board - something like this: MSI -- MICRO-STAR INT'L CO., LTD.
I've got it plugged in, in the case, with CPU and RAM. No post with onboard video, PCI card or PCI-E card. Have swapped out the RAM, trying different sticks in different slots. PSU, RAM and video cards were all working last time I used them.
When I turn on, the fans spin up, then slow down and I get 4 faint high pitched beeps. Doesn't sound like a usual beep code to me - it's not loud enough.
So any ideas? Next step is try it with an A64 3000+ I have lying around but won't be doing anything until Monday.
I've contacted the seller to let them know I'm having problems. Any suggestions would be appreciated.
Edit: CMOS cleared too.
Further edit: Nevermind - it's working!
