GPU reaches 70-73 degrees and computer restarts

[Justin17]

Hi guys. New to the forum btw.
I have this problem that happened recently. This weekend I installed Wildstar for the weekend beta and I started to have this problem with my GPU. The computer crushes suddenly. It just shuts down and than reboots itself after few seconds. I didn't know what was the issue, but after I ran some stress tests I found out that that is the GPU, which is reaching 70-73 degrees before the restart happens. Btw, I ran the test with Furmark. I have this PC for over a year and never had this problem before, and I used to play a lot of games, from WoW, Tera, Lineage2, DOTA2 etc. I even installed my latest NVIDIA GeForce GTX 560 Ti driver yesterday, but the problem is still there.
What could be the cause for it. My PSU is 750 W so I guess is enough energy for GPU. And why it happened only with Wildstar?
I would really appreciate if you could help me.

My PC spec is:
AsRock Z75 pro3 motherboard
Intel core i5 2500, 3.33GHz
Corsair DDR3 8GB
Energon EPS 750W
MSI GeForce GTX 560 ti 448

Couple things here.

- Get a different PSU. That thing is a crapper waiting to die and take some other hardware with it when it finally does.

- Invest in an after market cooler, like the Cooler Master Hyper 212 and some decent thermal paste. Should bring those temps down easlily.

GPU temp of 70-73°C is fine and just normal so that is not the issue, shut downs are power related possible so look into the PSU.

I know that temps of 70-73 are perfectly normal. But why it happened only this weekend? It's not like Wildstar is the only game that pushes my GPU hard. Could it be a problem with the graphic card itself? I can return it to the shop as I still have warranty.

GTX560 max temp is 99C. I don't think this issue is related to GPU overheating. In fact, 73C is a little bit hot but you're still on the safe side.
BTW, GTX560ti448 is a power hungry card. If your PSU wasn't a quality one it won't handle it under load. In fact, the behavior of the PC rebooting itself is related to CPU overheating or to power supply issues.

Well, it might be the PSU because I just ran a CPU stress test with Prime95 for 30 mins and it was no problem. So I will just buy another PSU.

It can be the card but could be the PSU since it shuts down. Are there any BSOD's involved?

Yes, not recently, but from time to time I get a blue screen with some hardware related problems. I am not that good in reading them. It worked well for a while tho after that. Still PSU?

Could be PSU could be board could me ram, first thing to do is disable autostart in bios on system failure so it will not restart on BSOD. If no BSOD just shut down then it is most likely PSU followed by the Board failing.

If it was the PSU it would shut down suddenly with no warnings or error messages, It's like unplugging the PC from the power source and re-plugging it again.
You are saying that you get BSOD.. Humm.. still could be your PSU, but I think other parts are failing with it.

No, the blue screens didn't occur when the computer crushed recently. This problem that I'm talking about with the pc restarting happened a few days ago. The last blue screen was like a month ago. So I never had this problem with computer simply rebooting when playing games before. Yes I had BSOD's from time to time, but it just stayed in blue screen, not rebooting. So this might be two separate problems?

BSOD could be caused by software issues/incompatibility between the parts (or externally connected devices)/failing parts. It's just another long story.
If you run a stress test, will the reboot happen? Or is it a specific application/game dependent? (Run realtemp with prime95 and chose "In place large FFTs" and see if the issue happens.

From what you describe, I can see that the problem happens when the system is under high load. What happens when a system is under high load is more power consumption and heating. The temps looks normal.. I personally still think that it's a PSU related issue. Your card is power hungry and it will shorten a non-quality PSU lifespan really fast. When a PSU is damaged, It won't be able to supply the PC with the power it's supposed to.

If you have another quality PSU laying around (Or you can always borrow one from a good friend 😛) test it with your system and see if the problem still exists.

As I said, I ran Prime95 CPu test for 30 mins and it passed. So the CPU is just fine. But, after I experienced the in-game issues with pc restarting, I ran a Furmark GPU test and at 73 degrees the pc restarted. So it is not only an in-game issue. It might be the PSU as I found out the one I have is a crappy one. I am already looking for another one.

Your CPU (MAX 95W) is barely consuming power compared to you graphics card (MAX 210W). I'd say go with the PSU upgrade as soon as you are getting a quality one.. A good PSU is a must have for gaming PCs and you can use it in future builds. Remember that a 500W high quality PSU can easily outperform a 750W low quality one.
Just let us know how it goes after the PSU upgrade.. Good luck
