Why don't various video cards power up?

3 days ago i installed a new A64 3700+ into my cousin's computer as an upgrade from a 3000+.

Obviously i re-built the computer pretty much from scratch, but as i recently did this a few weeks ago, it didn't take too long. Anyhow, re-plugged in his X800XT and the fan didnt spin at all. Suddenly i saw smoke coming from a small black PCB item (small black chip) and then we both smelt the burning hardware. Turned it off, freaked out a little, then tried again after plugging the video card in and out again. Nope, fan doesn't spin and so no display. Tried once again and behold the fan started powering again but the screen showed major corruption so i pretty much expected it to be dead. Took it home to a spare computer and it still shows corruption. So i am sure it is dead.

However.. His older card was a 6800 which was in my spare PC before i took it out and that works perfectly in my system. I phoned him and said 'look the x800 is dead, but i've still got your 6800 you can use' so i went round yesturday and thought it would be sorted in an instant. Fan still refuses to spin despite trying various power sources from his Hiper 580W! He has two harddrives, a DVD rom, the 6800, a 3700+ and a single TV card. I'm running twice that on an X-Pro 400W and i am pefectly fine.

Now i am worried that i have broken the 6800 too :o

Unfortunatly he is in London for a few days and so i won't be able to test it out in my spare machine that it was in orginally, but his whole case just seems to smell of burning GPU's. :(

We've hoovered it out, brushed and cleaned the AGP port and been pretty much gentle with it the whole time. I was worried that it could be that the BIOS of his Asus mobo not supporting the 'newer' cores of A64's, but there are no bleeps to indicate that there are problems.

Will re-built the whole PC from the ground up when i have time and see if that fixes it, but i am pretty unhopeful that will fix things.

Thanks for your time. :)
 
From what i remember, the CPU fan spins and everything seems to work as it did before apart from the GPU, so i think the PSU is still ok.

I've just tried having my 1950pro unplugged from the AGP port and with just the power for a few seconds and the fan didnt spin, so i'm assuming that the AGP port on his is faulty, considering when we fiddled about with it before the fan started working again? (all be it the X800xt was dead after it started smoking)

Could it be the CPU? I'm not sure on what BIOS he was running but i was pretty certain that it would accept the 3700+ SD. I may try and put his older 3000+ model in and see if that fixes it as a last resort. :o

Anyone else think what it could be? Mobo is Asus A8V deluxe rev2. :)

Edit: Just found out that his bios version doesnt support the 3700+. Would this stop the computer from not powering up the video card though? Also, there are no bleeps to suggest that something is wrong, its just silent. :(

i had the same problem once with a 3500 winchester ...no beeps or any thing ..updated the bios and it fired up 1st time
 
"Have you tried the old cpu with either card?"

Nope, not yet. However, i wouldn't have expected that to have been the issue (read below)

"i had the same problem once with a 3500 winchester ...no beeps or any thing ..updated the bios and it fired up 1st time"

I'm guessing that i would have to put the old CPU back in , update BIOS, then fit the new CPU in that order? I don't mind doing that if thats the case, just seems very unusual as i would have at least expected the video card to load up. I know sometimes you can update the BIOS by only using 1 stick of RAM etc.

Thanks for your help fellas. Now i'm pretty hopeful it will work again. :)
 
its just a case of elimination now, put the old CPU in, if your gfx cards work, then thats the problem, which means its worthwhile updating the bios, if not then something has died..
