hey i recently built a new computer
CPU : AMD Phenom II X6 1090T Black Edition Thuban 6 Core Processor 3.2GHZ Socket AM3 Retail Box
PSU : Powercolor Gaming 500W Powersupply ATX 12V 80PLUS CrossFire SLI 120MM Fan Powersupply
GPU : Gigabyte Radeon HD 6850 Windforce 820MHZ 1GB 4.2GHZ GDDR5 2XDVI HDMI Display Port PCI-E Video Card
MOBO : MSI 870-G45 ATX AM3 870 DDR3 2PCI-E16 PCI-E1 3PCI SATA2 GBLAN Audio CrossFireX Motherboard
RAM : Mushkin Enhanced Silverline Stiletto 8GB 2X4GB PC3-10666 DDR3-1333 9-9-9-24 Dual Channel Memory Kit
CASE : Apex SK-393-C Mid Tower ATX Case Black 4X5.25 1X3.5 5X3.5INT 4 X Front USB 2 X Front
but after playing battlefield for 30 min, my comp shuts down and wont start up again. i systematically checked my components and found that when i disconnected my GPU from the PSU (6 pin) my computer starts but without the graphics. i put the GPU in my friends comp with a 750W PSU and his computer wouldnt start either. so i know that my Gigabyte Radeon HD 6850 is broken but i dont know why. i built the comp brand new a day ago and the same day it breaks. im still under warranty so im getting a new card but i dont want to put it in my system if it is only going to break again. so my question is basically, should i be worried because of my build or did i just run into bad luck with a badly manufactured card. please help
