GPU overheating very fast
I have recently just got my computer working again and, as usual, something has gone wrong with my graphics card. When playing games, new or old, my GPU will overheat in SECONDS. Honestly. It will go from 30-40 celsius average, to 100+ celsius in under 10 seconds, sometimes longer with older games, which results in a black screen and computer restart. There was nothing wrong with my GPU prior, save for the fact that I let my friend borrow it while I was getting my new RAM. There doesn't seem to be anything restricting airflow or anything clogging the heat sink, and I reapplied some new thermal paste. There doesn't seem to be any damage or burning on the card anywhere. I've even adjusted my fan settings so that the fans run on max when it reaches 80 celsius. This has never happened before and it crashes on Skyrim, which it used to run at 40-50 fps. Help me Tom's Hardware, you're my only hope.

Hey,

you have to make sure that the heatsink of the GPU cooler is seated properly. When you have removed it to apply new thermal paste you might have placed it incorrectly so it doesn't do proper contact.

If the heatsink is seated properly and the fans are spinning then you should make sure your "friend" hasn't overclocked or otherwise played with the GPU while he was in possession of your PC. Probably the best thing to do (again after you make sure hardware-wise it's all ok) is to remove the GPU drivers and all associated programs (overclocking tools etc.) and install the latest drivers from nVidia's website. You can use the driver sweeper here http://www.guru3d.com/files-details/display-driver-unin... to remove the old drivers.

If the fan's and TIM are good I would question the PSU. It could be faulty.

Unless you're over clocking... In that case stop over clocking.

It was overheating before you re-applied the TIM, right? Also, are you sure the fan is spinning?
