Hi,
My specs:

CPU FX 6350
GPU SAPPHIRE R9 280 3G
8 GB RAM KINGSTON 1600 Mhz
Zalman aftermarket cpu cooler
WD 1TB HHD CAVIAR BLUE
PSU 650w Coolermaster bronze

Its a custom pc built one year ago.

My problem is that my pc every 2 months or more locks up , i mean it completely frozes and i cant
move mouse or use keyboard. No blue screen and no restarts.
I ve got all my drivers updated and i can play BF3 or ROME 2 and other games for days with zero problems. Yesterday i was playing Rome 2 Total War and suddenly in the campaign map my pc locks up and i cant do anything. Also the sound stops.It was the first time that i had this lock up during gameplay. The last time this happened i was just browsing back in August. It behaves very strange and i dont know if its a hardware issue or not.
I ve read this specific mobo has freezing issues but every hour or day as the other users have mentioned.
I am really disappointed and i would appreciate it if someone could help me or give an advice !!!
I am available for further information.
