GPU/PSU overheating to the point of PC turning off during games.

[Nullianac]

Recently, my GPU/PSU has been shitting out on me so hard that the PC turns itself off. Examples would be DOTA 2 and CS:GO. I'm not sure why this is happening, but I know that it is. I played a game of League of Legends earlier to find that my card just broke 90 Celsius, yikes.

Is there a possible fix for this? I've dusted most of the case's innards, getting out as much dust as possible. Best solution I can think of right now is what I just did - open up the goddamn case and stick a fan right there.

At least it's at 40 Celsius this way, but I need a more...permanent fix.

[EDIT]

Seem to have fixed it by moving the case infront of a window to get a breeze and aiming the fan directly on the GPU.

Was 40 Celsius before playing, ended and now it's 50. This was after an hour and a half straight of CSS.

You need to dust off the heatsing in the gpu.

This might require you to open up the GPU and use compressed air (no vacuum cleaner) to clean it.
If you remove the heatsink you will need to re-applt the thermal paste though. This might be needed annyway but try just dusting it out first.
