GPU 100% Usage and crashes

[Magikeen]

So recently my computer just started to crash whenever i launch a game, or anything that would require a heavy usage on the GPU.

The crashes begin with red green and blue pixels appearing on the screen and followed by a freeze, after a while the screen goes black and thats it.

I've already tried different driver's, also used DDU, cleaned the computer recently and checked if everything is place.

Reminder if i my GPU doesn't hit 100% usage it runs just fine, already tried some older games that only push my GPU to 40% and it works just fine.

 

GPU: Gtx780 TI

CPU: I7-4790k

PSU: CX750M 

Motherboard: Maximus Formula VI

Ram: 32G

 

If anyone has any tips or know's how to fix this problem feel free to share.

Are you overclocked? If so pull it back.

Bad overclock?

[Magikeen]

No i have never overclocked it.

It was running just fine yesterday.

Everything that's ever broke, was working fine a moment ago.

 

You could try a fresh installation of thermal paste and a good cleaning of the cooler. Can't hurt. Also give it voltage once you do that. Could just be getting old and needs some juice.

But i find it a bit weird that i can still use it, for any other task on my computer, it runs just fine with anything else, but once it goes to 100% usage it just crashes.

Can a simple cleaning solve it ?

(i am just wondering because at the moment i can't clean it so, looking for other ways to solve it)

Cleaning can't hurt. Why can't you clean it?

[Magikeen]

At the moment i don't have any thermal paste and all the stores are closed.
