GeForce GTX 750 ti suddenly games began crashing

[brandonstanfill4]

I have the GPU described above and every time I open a game I can use it for a few minutes then it will crash. Every basic program works and I can surf the web all day but if I try to open a game it will crash. I have tried Subnautica, Fortnite, and CSGO.

I have recently opened up my PC to dust it and just look around inside as I haven't in quite some time. I have also downloaded Nvidia's GeForce Experience and I updated to the latest driver: 390.77. I have tried reinstalling it and nothing changed.

Any Advice?

What PSU do you have? It's possible that it has reached the end of it's life and can no longer supply the required voltage under load.

I have an Ultra LSP650 650-Watt Power Supply

Ok, I don't know much about that brand, certainly not one of the big companies. The 750Ti doesn't require much power, so 650w would usually be considered overkill, but still doesn't mean the PSU can't fail....probably not helping you much here as I can't say one way or the other if your PSU could be the problem. If you had another PSU kicking around, it would be well worth trying it and seeing what happens.

Thought I'd look up Ultra PSUs on the tier list, it's where I thought it would be, tier 5 which isn't good. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

Thanks for the suggestion but it wasn't the PSU it still does it on the same PSU that my friend let me borrow

Ok. Just reading what you originally wrote, so it goes for a few minutes before crashing, and this is every game? Well if it's not the PSU, then maybe the card itself is overheating....this would make more sense than a bad GPU that would crash immediately.

I know you said you blew the dust out, but sometimes the thermal paste between the GPU and the cooler fails (dries out or looses good contact) and the heat can't get away. You may want to monitor how hot the GPU is getting, and what % the fan is running at while gaming.
