I upgraded my main desktop machine and pulled the following parts out:
1. AMD X2 64bit 3800+
2. ASUS A8v motherboard
3. Two 1GB DDR PC3200
I'm adding to that:
4. Earthwatts 580(?) PSU
5. Two 512 MB DDR PC3200
6. ATI HD3650 (or Nvidia 6900 GT or something)
7. 32 GB Patriot
After plugging it in the mobo health light turns on.
Power button starts all the fans spinning, the CD Rom starts spinning, but I never get a POST beep, and nothing appears on the screen.
I started trouble shooting by removing all but the CPU, RAM and Video Card but again no change.
I then remove the video card, no change.
Remove the RAM leaving on ly the CPU in and then I get 1 long, two short beeps. (Good!) that means it knows RAM is missing.
Plug the ram back in and again nothing.
So I read about this EZ-Flash feature. I burn a CD with the rom and put it in the CDROM. I then hit the power button and press ALT-F2. EZ-Flash appears on the monitor and proceeds to update the BIOS from the CDROM. After a reboot however, no change.
I've also tested it with a MUCH stronger power supply that I had used previously with these parts but got the same, fans spinning and no video.
I believe that the mobo is fine since I was able to load from CD, display video and detect missing RAM, but what else? Could it be the CPU has somehow gone bad? It was working a few days ago.
