i only watch movies and play games .i haven't tried any thing intensive on my rig except gaming. btw how to take screenshot of fan speed? i only know fans r running at full speed when they make so much noice
op- I said post a screenshot of 'speedfan' not 'fan speed'. Speedfan is a pc temperature monitoring tool.
Download speedfan (google it), install it, run game, minimize the game, open speedfan and take a screenshot and post it.
Also, try running prime95 (stress test utility) and report if the system still shuts down.
