Overheating GPU

Past few days my GPU has been overheating for some reason, really have no idea why. In Furmark I get around to 111C then my PC just loses all display until I have to hard reboot.

I idle at around 50C

Obviously my card is overheating,

Think a heatsink died? Airflow is just fine, my case is a big beast and all the fans are running.

Any ideas on fixes other than just getting a new card? One thing im confused about is, until my PC shuts off, the games look great. It just dies. So the card is causing the PC to just lose display due to heat I assume?

Screen goes black, computer and video card keeps running (I can hear the fans, they're maxed) then I have to hard reboot.

Power Supply: Cooler Master Real Power 1000W

Case: Cooler Master ATCS 840

RAM: 12GB DDR3 1600MHz PC12800

Motherboard: Asus P6X58D Premium

Graphics Card: Geforce GTX480 1536MB DDR5


This JUST started happening after about 2 years using this rig flawlessly.

check out the thermal paste and see if the fan is spinning properly.

Pull the heatsink off the GPU, clean off old thermal paste, apply new paste. Re-attach heatsink. Be sure the heatsink is making good contact with the GPU.

Be sure to use a good thermal compound. i.e. Arctic Silver 5 or something similar.

I've never done that before, so it's pretty much guaranteed to be the heatsink then?

Anyone know of a good online provider of this paste?

If you find no difference after you replace the thermal paste and put the fan settings high, yes the GPUHSF is maybe bad... Could be

The black screen is a failsafe at high temp I assume?
