Recently (last 1-2 month) I've been experiencing crashes on my 8 month custom built PC whenever I play intensive games. The computer does not shutdown completely, my monitor only goes black and sometimes I can still hear and talk to my friends on Skype. I have opened my case and I noticed all fans still running EXECPT my two GPU-fans so I assume the GPU just shuts.
Here's my specifications:
Case: Fractal Design Define R4
Storage: 1 WD Desktop Black 1TB & 1 Kingston SSDNow V300 120GB 2.5"
Motherboard: MSI Z77A-G43
Memory: Corsair Vengeance DDR3 1600MHz CL9 4GBx2
Power: Silver Power SP-SS500 - 500W 80 Plus
CPU: Intel Core i5-3350P Quad Core 3.1Ghz ((Overclocked to 3.3Ghz))
GPU: XFX Radeon HD 7950 3GB
Liquid CPU-Cooler Cooler Master Seidon 120XL with two stacked 120mm fans blowing air out (The speed is depending on the CPU temp)
Two 140mm case fans taking in air on the front. (On full speed all the time)
(My case also have highly effective dustfilters which I regularly clean so theres where little dust inside my case.)
I've tried to keep track of the temps (Like when playing Battlefield 4 for example, which runs pretty good on Ultra preset @ 1920x1080, execpt when it crashes lol) before the the crashes occur and the GPU temp never seem to exceed 74C. But it kind of seem like it's some kind of overheating problem because after my computer has crashed/turned black I can not start using it again right away but waiting like 5 minutes if I leave it off, but I have realised If leave it on (By "on" I mean all fans running as they should but with a black screen), I can start my computer propely after 30~ seconds again. I have just have a grain over basic knowledge of computers but as far as I know that indicates an some sort of overheating problem? But then again the GPU and CPU temps are more than fine, leaving me preeetty confused.
The only solution right now that works is turning the graphic waay down depending on what game I'm playing.
I can't think of any more details, execpt maybe that I've ran FurMark and my PC only makes it 50 sec - 2 min till the gpu shuts down.(again, the gpu temps are fine when it crashes, something like 75C ) And the crashes vary from 7 minutes to maaany hours depending on what settings I play on/what game I play.
I would be really really appreciate if you guys could share all you ideas that you may come up.
Just tell me if you need any more details etc.
If it´s under the warranty period which it seems, you can return it but you have the make sure it´s the gpus fault, Don´t know if you can stretch your budget a little more for a better psu, it´s not that the one you linked is bad in fact is a good choice but remember that in the psu is better to buy the best, it´s the most important part of your build.
