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.
