Gmod crashes after 5~10 min of gameplay and resets computer

Hi guys. I’m having trouble with my Gmod: after playing for some time, my computer suddenly resets. It’s happening with other games also like “The Sims 2”, “Prototype” and other GPU intensive games, and i’m REALLY getting frustrated. And also i miss playing Garry’s Mod.

Thank you very much. I hope you can help me

Your GPU might be overheating, make sure the inside of your computer is free of dust and your computer has proper air flow.

i’ll tryh that. But i’ve been monitoring my GPU temp and it crashes with just 80~90 degrees Celcius

That’s kinda hot.

really? Hum… any ideas how the lower that temperature? i’ve already opened the computer case so it could have a better air flow

My PC is full of holes,
so it doesn’t burn and explodes to death,killing me along an all the world,causing the RAM to die in little pieces…

wel…do you have any problem with sudden reset crashes and stuff?

Yeah your problem is the GPU overheating. I know because i had this problem before. My pc was bought with it though so i called customer support and they sent me a new one with a bigger fan and heatsink. Fixed it perfectly.
