Advice for my [possibly] dying AGP slot...? Please help

Edit: Well, now it doesn't even always boot...sometimes the machine turns on, everything spins, hard drive light comes on, but the video doesn't go. If I switch it off and wait ~5 mins, it's ok.

Also, the area around the north bridge gets fairly hot too...like about the same as the CPU heatsink (even though the system wasn't under load for the time that it was on). Seems like I've probably got some damaged voltage regulators in there...

I suppose it's replacement time. Yay for $51 mobos from newegg...hurrah for Biostar, lol.

Hey all,
I just wanted to check this with you guys right quick...wouldn't want to spend $50 on a new motherboard if I don't need it.

To start...I used two comps to test--one with an 1.2duron and ECS k7s5a, 256mb ram, one 40gb, one optical drive. Other was a 1.33 tbird, epox 8k7a, 2 hd's, 1 optical, 256mb ram. Both machines have identical Enlight 300W PSUs.

Whatever I put into the Epox's AGP slot seems to heat up real fast. I tried this with an Radeon 9600 and a ATI Rage IIC (AGP). And that was just sitting in windows--not even under load. The 9600 wouldn't play games at all (w/o locking up). I tried everything from drivers to disconnecting all other components to swapping power supplies, and the 9600 wouldn't play games on the Epox.

But it was perfectly happy on the ECS. And it ran cool on the ECS, even after 2 hours of Far Cry. The Rage IIC was happy on the ECS too--no heat issues there.

I tested both motherboards with a Matrox PCI video card--about the same temperature on both.

Anyhow, I tried unloading the Epox's PSU by disconnecting components--no good. I also swapped the PSU's between the two machines...no good (btw, with the Epox's PSU hooked to the ECS, the AGP cards there still ran cool). I also tried a smaller 250W with the Epox--no good...still hot.

Note: I "measured" temperatures by touch. The cards in the Epox's AGP slot were *noticeably* hotter...like, hurt your finger hot.

Anyhow, this makes me think my Epox's AGP slot is screwy. I recently had a Geforce2 pro crap out on me (in the epox); it's cooling fan died...and it eventually died an overheated death...after which my system would not boot until I swapped video cards.

I'm thinking the AGP slot was damaged?

Any advice would be appreciated...otherwise I'm going to purchase a Biostart M7NCD in two or so days.

P.S. AGP voltages were at default, the buses were not overclocked, fastwrites off, etc etc.

Your testing convinces me that there is a problem with the Epox board, and you need another one. Sorry we can't be more helpful. Let us know how it works out. Peace.

Ok, thanks :)

That is essentially what I am looking for--affirmation that my AGP slot is screwed up or other tests I should try before writing off the motherboard.

Thanks again,

Nope, I don't have any jumpers or BIOS options to change the AGP voltage...so it's all managed by the motherboard (and I suppose the mobo is managing it badly).
