pc turning off and on in game

[sweinhart3]

i have been watchin the temp it has been normal. and like i said have 5 or 6 fans on it and i just bought the new power supply 2 months ago, was a 480 watt and kept kicking me from game, and then i bought the 500 watt one and now it is shutting dwn and then re powering i tup so i am running out of options... so where i am at what should i do i have monitored all and i have wiped the hard drive there is nothing on it other than the game and operating system... before there was a lot of stuff so i dont see how it is being over loaded
