i just installed a new motherboard/cpu and now my gpu is overheating its 113 degrees and causes my system to reboot whenever i play a game i installed new version of windows installed the latest drivers and bios is up to date. before i had a biostar mobo and athalonx2 cpu and the same gpu it ran fine any help will be appreciated. On a side note will a gtx 570 work with this mobo.

mobo asus m4a78lt-m
cpu phenom ii 955x4
gpu ati raedeon 4850
psu antec basiq 500w
ram 4g kingston

Maybe the fan on the 4850 broke while you were swapping motherboards? 113 is insanely hot and will damage your card. I would open the case and make sure the fan on the GPU is actually working. And yes a 570 will work on your motherboard, but you would probably want to get a new power supply.

Broke fan is possible. Did you try cleaning the cards heat sink before putting it back in the computer?
