I built this pc 2 years ago and it ran fine for the first 6 months after which i started getting driver crashes and shutdowns while gaming. I managed to solve that somehow by underclocking the graphics card and faced no problem until recently. Just about a month ago, i added a new cabinet side fan which brought down my gpu temps by a good 10 degrees from 70 to 60. But after two weeks, my pc started crashing randomly while playing games. I've searched though the internet about this and i think its my psu that is going bad. But again the pc runs fine if i try to run it on the integrated graphics and shuts down as soon as i plug in the graphics card, therefore i can't decide whether its my gpu or psu that's causing problems.

My Specs ::

core i3 2120
intel dh61ho motherboard
palit nvidia gtx550ti 1gb ddr5
coolermaster thunder 450w
4gb corsair ram
1 HDD
2x 120 mm cabinet fans
windows 7 64-bit
