I have a XFX 9800GT that I bought over a year ago.
When I bought it, I promptly changed the thermalpaste to apply Arctic Silver 5.


Now, the card stopped working.
When I plug in the 6-pin power connector, the PSU won't start. If I unplug the 6-pin, the PSU can start.
Heck I tried with different PSU's.
Even with the gfx card not connected to the motherboard, plugging in the 6-pin connector will cause the PSU to shut down. [PSU started with the pin trick to link the green wire to a black wire]

I'm 99% sure it's a defective diode [not temperature diode, but this sort of diode (http://en.wikipedia.org/wiki/Diode). I had the exact same symptom [PSU shutting down] with a hard drive. All I had to do was replace the burnt diode.
Though, for the gfx card, whichever one is broken is not visibly burnt, hence I cant find it.





ANYWAYYYYYYYYyY - I'm not sure if having changed the thermalpaste has voided my warranty. If it has, I'd risk fixing my gfx card. If it hasn't, I'll just RMA it.

I'm pretty sure as soon as you remove something from it then you'll void the warrenty.

If it's still in warrenty then I would go with that (as long as your not with XFX, they took 3 months to replace a 7900gs and it still cost me 20 quid to repalce it... Terrible service.

I had the opposite exp. with xfx. I sent them my 295 the week before last, and my new 295 is expected to arrive on the 4th :thup: They have been excellent to me, answering my questions and such.

Reccomended :)

As far as your warranty goes.. Hmm. Tough call. Send it in anyways, the worst they will do is send it back to you

Yea always RMA if you can first,, NDA if your desprate. fixing it under warranty is walking a tight-rope if your's dont work you just voided a warranty if not carefull.
