There is something infuriatingly wrong with my PC. I turn it on, log in, and then it just freezes or restarts (tends to freeze more often), or popping up the Blue Screen. Every time I want to use my PC, I have to log in, then be prepared for it to freeze up and restart it, and sometimes I have to repeat this on several occasions just so I can use the [bleep] machine. Running several programs at once may trigger this, and gaming makes the PC particularly susceptible. The problem wasn't always like this, although over time I have noticed it getting progressively worse.
MB: MSI ms-7360
CPU: Intel Core 2 duo E6750, 2.66GHz
RAM: DDR2 2GB Generic brand
GPU: Nvidia GeForce 8800GT
PSU: Flexiglow 500W
One suggestion has been that the Flexiglow 500 might be the problem, as it is just enough to power an 8800GT. Also, it gets some average reviews which mention stability problems under stress - this may be the malfunctioning device, or I may be wrong.
Any help appreciated
