yes sorry guys i have a 700watt psu... recently i have played for 45mins with no issue because i enable vsync, and noticed in BIOS my PCIE freq was 101, ive downgraded to 100... oh like i first mentioned i did a full clean before playing including using gas duster to de-clogg everything...! all is well at the mo

thank you for you replay, i actually did a full clean before running the game for the first time, played well for the first 3 hrs, now its every first 10 15 mins into game play... however my IOH temps run around 75-80c while playing, i forgot to mention that i have artic coolers in there, one on the cpu and 1 running out the system?

about 10 mins into the game my computer just shuts off as if i have pulled the power out... and every driver i can think of is up to date.! my spec is..
