First of all, i'm French so... Sorry for my English.
I recently build a computer for the first time, here are the specs :
Motherboard : M5A97 Pro
CPU : AMD Phenom II X4 955 BE
GPU : MSI R6870 Hawk
Ventirad : Cooler Master Hyper 212 Plus
PSU : Antec HCG 520
Ram : Kit dual channel DDR3 Ripjaws X, 2 x 2Go, PC3-12800, CAS 9, G.Skill
DVD writer : LG GH22NS50
Hard drive : Caviar Blue 500Go
Wireless card : TP-LINK TL-WN951N
All in a Zalman Z9 Plus
The problem is that when I play Crysis, my computer is shutting down after 30 minutes, and doesn't want to restart... I have to unplug the computer and wait 1 or 2 minutes...
Temperatures seem to be good, CPU : 30°C GPU : 38°C and 40°C/46°C playing Burnout Paradise
But my bios says my CPU temp is 44°C
I also tried to launch FurMark test, and 2 sec after the beginning, the computers crashes...
After that, I tried OCCT, CPU stress test seems to be ok, gpu stress test makes the computer crash after 2 or 3 minutes, and PSU stress test makes the computer crash just after the beginning, before the screen appears...
Is my PSU defective ?
It's the first time I build a computer, therefore maybe I have made some mistakes...
