Comp Shuts off after 20 minutes / new graphics card.

#1 - Oct. 4, 2012, 4:19 p.m.

Today I installed a geforce gtx 550 ti and sense then when I play for about 20 minutes my comp completely shuts off. I’ve been scouring the web and have come up with the usual culprits such as power supply not efficient enough and overheating. I have been monitoring my temps and while in game shortly before it shuts off it hits about 66 degrees celsius, which doesn’t seem high enough to cause shut down. ( however, my case does feel hotter than normal right after shut down)
I popped open my comp and I have a 500watt power supply which I believe to be strong enough to run the card…but i suppose there is trouble with it trying to run everything along with the upgraded card?
I do have the most recent Nvidia driver….seems like that update is giving people problems.
I played about 30 minutes of Diablo 3 without shut down.
Some Specs:
quad core 64bit processor 3.60ghz
8 gigs of ram
MOBO model number: M68MT-S2

When this happened to me, and it’s happened more than once because I’m a bit of a video card junkie, it’s been related to one of two things:

Inadequate Power Supply
Overheating

When I was beta-testing StarCraft, I had to open the box and run a room fan through the system to keep it cool enough to run the game. Ok, that was 1998. However, the same issue occurs today with powerful (and hot-running) video cards.

Also, check the requirements for your system and look at your PS. I had the weirdest set of “symptoms” related to having an inadequate power supply, including really bizarre graphics in GW, but it all sorted out when I gave my computer more “juice.”

Thanks Gaile, it might just be my power supply…just wishing it wasn’t hah.

I did a piece-by-piece rebuild, and I really never thought it as the PS. I mean, it should have had more than enough power, the greedy little beast! And yet, it was replacing the PS that fixed it, so I can’t argue with the process of elimination.

Good luck with the issue – I know how frustrating that is. And the TS team will try to help you, don’t forget!
