Computer won't boot - no video, 2 single beeps

The other day, my computer suddenly stopped booting. I have an Asus P5Q Pro mobo, running AMI BIOS. When I power the box on, everything fires up (fans, disks, peripherals), but I get no video. I hooked up a case speaker, and the BIOS error code is a single beep ~5 seconds after powerup, and then another single beep ~10 seconds after the first.

The AMI BIOS apparently uses 2 beeps to indicate a memory parity error in the first 64k, but I would think those 2 beeps would be closer together.

If I remove my sticks of memory, I get the standard memory code (1 short, 3 long). Trying single sticks in either primary bank has no effect on the original condition.

I popped the CMOS battery, which seems to have had no effect.

Any ideas?

My guess would be your Graphics card or your Motherboard.

I've had a few ASUS MB's die on me with the exact conditions you are experiencing.

This may be an issue where the PSU has decided it won't power up the video card anymore. Among the video card you have tried was one of them a low power one that doesn't require a PCI-e power connector? If so then its looking like a motherboard problem.
