GTX 480 cooking itself

The last week or so I've been having some rather large PC problems, normally resulting in no video output from my graphics card unless I cleared the CMOS. After a few BIOS updates I seem to have a stable video feed, however my graphics card is idling at 92C!

Any ideas what can be causing this?

To try and sum up what has happened;

PC started acting oddly, would seem to not boot up image after turning it off for the night.
Turns out image was coming through on board video (even though set to auto).
Was able to boot into Windows 7 and linux, but no graphics card was detcted.
Cleared CMOS and moved GPU to 2nd PCI-E slot, had video for the day.
Turned off for the night.

No video the next day.
Spent a few hours moving the card around between the slots, would get video every now and again, though would cut out after 5-10 mins.
Removed NVidea drivers, reinstalled.
Card started to run very hot, and would still loose video feed.

Tried many other drivers (all 3xx WHQL drivers, 310.XX Beta Drivers, and 296.10 drivers and a few others in the 2XX.XX lineup).
Card continued to cut out/run hot/undetected.

Then went on to updating the MOBO BIOS.
Newest one went really bad, and couldn't access the BIOS (some UEIF high tech version)
Tried a few more, currently using Version 4 of the BIOS from Gigabyte.
[Used the boot USB disk not the @BIOS program].

Currently I have video using the 296.10 drivers and version 4 of the BIOS for my motherboard, but the card is running ridiculousness hot. Was at 92C, decided to try a game (Farming Sim 2013 Demo) and within 3 mins the temps were over 100C and rising (as you can guess I closed the game straight away). Since then the fans have been stuck at 90% and have kept the card at a nice and toasty 71C.

I've cleared the card of the small amount of dust using compressed air (also removed the plastic casing to really get into it), but it hasn't helped.

The card seems to run relatively fine till I install the drivers. Removing the drivers and restarting the PC everything is quite. I can't get the temperature reading though as it just shows up at 0C if at all.

Once I install the drivers (but before restart PC) everything is fine, I was able to get a reading of 72C which is still really high for idle.

If I boot linux (hasn't got proper Drivers, just default ones) the PC runs as before, almost silent with a bit of warmth from the top vent.

Think that is everything that has happened recently.

I built this PC just over a year ago sourcing most parts from else where, but the GTX 480 from here. I'd like to think that the power supply has gone, but as the card isn't always roasting I'm not so sure. All the other parts seem to be working as well, I'd figure if the PSU was a gonna other anomalies would occur.

PC Specs
Gigabyte Z68XP-UD3P
I5-2500K - Artic Cooler 7
GTX 480 PNY
8 GB Ram
Thermaltake Dokker Case with extra fans (one directly towards the GPU)
XClio 750W power supply
 
I'm 90 % sure yes, as soon as I boot up windows the first thing I would run is open hardware monitor (but also used MSI afterbuner and GPU-Z). The temps would hit 92C. If I turn off the machine and put my hand near the heat pipes they feel rather warm.

Unfortunately I can't try in another PC. I'm at Uni, most people have a laptop (which are smaller than my card).

I've just removed the drivers again (not rebooted yet). It gives my ears a rest and the air out the top feels a lot cooler.

Psychodil, I have not tried that no. However the card is 1y 2m (just outside Overclockers Warranty), but possibly in manufactures. Would rather not risk voiding that just yet.

Not sure, it was a referb. It's just outside the 1 year warranty from Overclockers. PNY seem to state that their cards are under a 3 year warrenty, however OEM/referbs are negotiated on a case to case bases.
