My computer kills my Graphics card

Alright so about a month ago I had my 8800 gtx. I forgot the error that was occuring in event viewer but i tried everything but couldnt get it to fix, it kept making my computer crash. Then all of a sudden, dead. the computer went black. I got a replacement 8800gtx and about a week later the same thing happened, crashed a little bit then dead. So i decided to buy a gtx 260. Ive had it for about 2 weeks now and i started to get a different kind of error, and crashes, then today. dead... black screen. I dont have the error off hand but it had something to do with JRAID 1 scsi. Something keeps killing my video cards but i cant figure out what it would be. My specs are: gigabyte p35-ds3r, quad core 6600, one 80 gig raptor and one 500 gig seagate. 2 sticks of 1g ddr2 800 crucial ram, sound blaster audigy 2 zs, and a 650w psu. Ive done plenty of tests when the cards have been dead to prove that the video card is dead. but i just dont know whats causing it. ive removed ram, removed my sound card. its just not adding up. anyone have any suggestions please let me know.

And check out if u have plug in 2 6pin pcie connector in ur card. There are 2 connector either of them open the card will not get enough power and pc crash when in load. So check that out also

Could be a overheating problem, check your air flow.

If you still have the other cards try them in another system if possible. I agree that it may be a psu issue.

I have an Antec Tru Power Trio 650w. I dont have the right connection to be able to use onboard, if it even has it at all. I have tried putting my friends card in to test it out and his works perfectly. Idk why this all of a sudden started killing them.

when it would crash in game, i would get a black screen and it would flicker near the top. then i could sometimes alt tab and i would have artifacts. i usually always saw some artifacts. no strange noises though. my friends going to let me know whether it works or not.

Also it was crashing in game then last night I came home from work and the screen had tons of artifacts, it was idle and not running anything. When I restarted it that's when I was getting the black screen

Also if it is the PSU it may have screwed up yer mobo and anything attached aswell further adding to yer issues.Buy a new PSU and stress test yer PC to see if nothing else has been damaged by the bad PSU.And for the sake of ruling out any other probs , strip down the PC and test the memory and check yer cables to insure they are plugged in and also to make sure there is no lose connections.

It has to be the psu very little else could be causing the problems. Did you ever have drives that would stop responding or would restart since with many PSUs feed the card and drives on the same rail for most tri rail antec units. Two feed the cpu through the eps4pin or the 8pin while the last rail feed the card and drives. Like with my antec ea650 the first and third rail feed the cpu while the remaining on does every thing else. I have managed to run my 8800gtx with loads of drives and fans while a 9800gt (65nm) was shoehorned in with the molex to 6pin. So I think you got a dud of a psu or have greater needs than what it can deliver.

Alright just tried a new psu and I still had a black screen.. So it has to be a problem with the mobo then doesn't it

is ur friend's card same as urs? if so then it is most probably ur pci express lane in the motherboard

DON'T GO TO BEST BUY BIG RIPOFF!!!

Best Buy is extreamely over priced go on newegg but if that is out of the budget ebay would still be better than best buy. Can't wait look up online to see if there is a Goodwill computer works in your area. I bought a nice Enermax in my town but one day when I didn't have much money I missed out a 700w dual or quad rail one by the same brand.

I just ordered a new mobo since the different psu didn't work. Do you think it's still possibly the psu that did it or could it just have been a faulty mobo. I don't want to buy a mono only to break because of the psu. It's a good brand psu, I don't see why it would cause problems only for the specific gpu slot.

Did you try the same game at the same level that causes problem in ur pc? Because it maybe the card itself having bad memory. I had a problem with fx5200 in some games i could see artifacts but in some i dont see anything. I sent it out in the shop and went for a fx5700 and everything ran just fine. But in my case the pc ran fine everything ran fine only in some games i could see artifacts and that was a graphics card problem. But in ur case ur pc is not posting. But ur friend's pc is posting. So thats probably not card problem. Then ur friends card ran fine in ur pc u said. Then probably not the psu or the mobo problem. The only thing left is overheating issue. Else i dont see anything else that could cause the problem. Quite strange problem. U should consider talking to specialist in australia maybe if he look at ur system he can figure out whats causing the problem.

I see RAID and SCSI...sounds like a HD problem to me...

If that is a hdd problem i think atleast the pc would start or post, right? he said the pc is totaly blank/dead or not posting anything or black screen. If the problem is in DIMM or RAM then it wouldnt post after inserting his friend's gfx, and also without appropiate ram installation u would hear beep.

btw its not "bad" to have more than one rail on your psu. especially if its a good brand. like antec, which i have
