Computer Crash Graphics or PSU?

[Jaxom120]

Ive been Having problems with my PC lately. It tends to crash whenever my graphics card reaches 60 degrees. Now after doing some careful testing I have isolated the problem to either my Graphics card or my PSU. I used to be able to play games like skyrim on high without any problems but the recent crashes are making gaming really hard. Any help would be greatly appreciated.

My Specs are:
Motherboard: ASUSTeK Computer INC.M3A78-VM
Processor: AMD Phenom(tm) 9750 Quad-Core Processor (4 CPUs), ~2.4GHz
Ram: 8192MB RAM
Graphics; NVIDIA Geforce GTX 550 Ti
PSU: StealthXStream 2 700W (700 Watt) TN7O03

Anyhelp would be greatly appreciated.

Hi

Well the best thing to do to check your psu is to buy one of this.

Its an extremely cheap product but very helpful it definitely worth its money.
Check your psu and if everything is fine then you need to concentrate on your gpu! You can download gpu-z to check your graphics card.

P.S. I would recommend to check both hardware before taking anything out!!

Hope this helps!
