Crashing, Rebooting, and Instability

Hello,
Have n interesting problem here. I installed a new power supply about a week ago, and today when i go to start up my computer it goes from the ASUS intro straight to Windows Error recovery. So i did not do that the first time, and right after i hit enter on run windows it rebooted. and back to the windows error recovery i go. Went through did the recovery and it rebooted. I left it for a minute and it just keeps on repeating the cycle. I managed to launch windows once. completed a scan disk and memory diagnostics, and nothing. So i tried to play splinter cell conviction, and it starts to load that, then it reboots, entering the same cycle as it did before...and the worst part of my luck is that i originally turned my computer on to back it up, so much for that.

Hope you can help.

Thanks for the idea, but it didnt work, i'll check out the tutorials in the meantime.

could it be when the old one died a surge damaged the motherboard or cpu?

Thanks for the ideas. With the capacitors they are solid Japanese capacitors, if that means anything, but they had no bulging or discolouration. and reseating the drive cables did not work. still working my way through the tutorials.

Just to let you know I found out the problem. It was the gpu. When the old psu went, i am guessing, that it caused it fried it. I put it through a 3d mark 06 test on my other computer and it overheated.
