strange gf260 behavior

[Likwid_Nitrogen]

A couple of weeks ago, I came home after a few days out of the house.
Turned on computer, video card fans turned on, but bios beeped a video error.
After repeating a few times, video card fans stopped turning on on boot (card didn't turn on). I messed with the two power inputs and such, with no change. I decided the card died and RMA'd it. Replaced the card with an old gf7950gt, which worked fine.

Got the card back from Asus, and it still didn't work. Spent a while trying to find another test system with two PCIx power adapters and a big enough case, and couldn't. I had one 2x molex to PCIx power adapter, and journeyed to Fry's to get another. After hooking up the power this way, the GPU turned on, and system booted fine.

After deciding that this didn't make much sense (my PSU is a good, newish modular SeaSonic), I tried again with the original PCIx power connectors. It worked.

That seemed like a good time to quit messing with it, so I'm still lost as to what actually happened with my GPU.

Anybody have insight?

Maybe the card wasn't seated correctly?

Sounds like a bad motherboard to me.

it was seated and reseated a number of times

Maybe it wasn't gett sufficient power and by fiddling with the power connections it gave it that little better connection to get going. Maybe the card is intermittently bad, they sometimes don't just fail outright.

Hope it runs fine for you now on.

i agree...my brothers 8800gt has something wrong with the clip on the power plug and if its not completely pushed in it makes a banshee scream from hell.
