So, my computer randomly stopped working for no obvious reason. I shutdown one day, it's fine. The next day, bang, no video, or even a motherboard beep or floppy check.

Whenever I plug an AGP GPU into my motherboard, the computer doesn't boot, or display video. If I use the onboard graphics or a PCI 16 card, it boots and displays video just fine.

I tried the AGP card on another motherboard, same exact story.

So, I bought a new AGP card. Same thing happens on both boards (both cards are NVIDIA). I bought a new power supply with a single rail, upping the amps to 48 rather than 20. Still doesn't work.

Any thoughts? It is hard to believe two bad MB's or two bad GPU's or two bad PS, yet one of them has to be the case.

EDIT: I did some Googling, but all I could find was bad PS (not a chance) and bad BIOS battery (entirely possible) so I'll test the battery tomorrow and try setting the BIOS to AGP if it has such an option.

Could be a couple of bad cards.

What cards are they exactly? If its AGP it must be oldschool and might need a PSU with a 5V heavy rail.

Heh yeah they're pretty ghetto, but I've been holding out on replacing my board and CPU.

One is an nvidia 7600GT, the other is a 7950GT. Not great cards, but the 7600 has worked well for a couple years, and the 7950GT was new in a box to replace it.

I wouldn't be surprised if the AGP slot on the board is dead.

Normally, neither would I, but I would be *very* surprised if the AGP slots on two boards died at around the same time. My dad is going to stick it in my sisters computer at home when he gets the change to test that idea further.

You're sure it's not something as simple as a BIOS setting needs changing? That's where I'd look before splurging on parts.

I'm going to try that today, I never even thought to consider a dead CMOS battery.

If that's the case, I'll feel like an absolute moron, but at least I'll have a nice power supply, I guess. >.>

It could very well be a bad BIOS battery.

But you tested the second AGP card on the old motherboard and with the old PSU, first? A failure (probably electrical in nature) on either the original motherboard or PSU could have killed a perfectly good AGP card, leading to a "failure" on other, good set of hardware. Just a thought.

I replaced the battery, no joy. :(

You're right about that, but I'd like to believe that's not the case, if only to keep my sanity.

I'm almost certain it's a BIOS issue. If I force AGP, and don't have the card in, it spazzes out with a cascade of beeps that don't follow any error code I've ever heard of. With the card in, it does it's normal black screen no POST crap. It definitely sees the card, it's just not doing something quite right. A bad battery would explain why it appeared to break right after a reboot. The card showed video until power off, but didn't even tell the monitor to wake up when I powered on.

Any AGP BIOS settings wisdom for Biostar Phoenix? I'm Googling and oogling, but all I can manage is to recreate the random beeping, which is only fixable by using a jumper to reset the CMOS.

Have you tried disabling onboard video if there is such an option? Best to uninstall the display driver, power down, unplug GPU, boot into BIOS, disable onboard video if there is such a thing, power down, plug in GPU, power up, and reinstall display drivers.
