dio wroteHey all,
Been having a bit of an issue with my old desktop at home, like 7/10 times when i open a game (dota2/csgo), as soon as im in a game, the PC will restart.
I used to get around this by changing the video to Windowed mode, but now that's not even working anymore. I ran Furmark for like 45 minutes via GPU stress, it was fine.
I tried installing the latest drivers, nothing helped.
Something strange also happened yesterday, I logged on to CSGO, i started the game, the monitor turned off and one of the fans in the PC just began to spin really fast and loud. I had to restart.
Any suggestions would be helpful.
Changing to Windowed mode engages Windows DWM Triple-Buffered V-Sync, which limits the framerate your games are running at. When in Exclusive Fullscreen mode, I'm assuming you have V-Sync turned off, which means your framerate shoots up, your CPU utilization goes up, and your GPU utilization goes up.
Given these games probably do not come close to using enough power from your PSU on the CPU and GPU that it would exceed that drawn due to Furmark on the GPU solely, then running Furmark indicates that the GPU and PSU are not necessarily the issue - that is, your GPU core seems fine and your PSU is handling a higher power output fine.
Run a CPU stress test (e.g. Prime95). Your CPU sounds like the culprit.
vlatkozelka wroteUnrelated but ... don't use Furmark, it puts too much stress on your GPU, VRam and VRMs, it's basically a card killer. Run something like heaven, or some other realistic benchmark where you're rendering something similar to a game.
Drivers for modern GPUs detect when Furmark is running and proceed to limit power draw and possibly clockspeeds.
