I wish I could run my BIOS in a debugger.

Help me guess which part of my homebrew PC is causing my POST video failure.

I built this box six months ago. Its stability has been flawless. Now, suddenly, my POST keeps doing a <long>beep</long> <short>beep beep</short> which for my BIOS is a video failure. It then boots sans video. If I unplug the power and fool around for 15 minutes or so (that's as precise as I can be after a couple evenings of despair) it will boot with video again.
This is my parts list
; here it is on Newegg with moar linkies
if you have a login there. The proc is a 45W Athlon X2 and I dual-boot XP and Ubuntu. There are a few vaguely related prior questions but I couldn't find any love for my particular crisis. I'm having the same POST error as phrontist here
, but he had a notebook.
Is it the:
- Video card? It's a fanless NVIDIA 8500, which is allegedly somewhat fail-y due to the passive cooling. However, the system has never had any instability or lockups in six months and when it boots again after fiddling it's rock solid.
- Motherboard? The fact that the system is stable once it boots makes me wonder if maybe the BIOS is somehow flaky.
- PSU? It only boots now after the system has been unplugged for a while...
I talk big but I am fairly ignorant about hardware and haven't built a system since like 2001. All of the above is (I think) returnable but the software developer in me wants to know what is going on. What do you think is wrong? What would you do in my shoes?
