So i'm happily reminiscing playing a game of Half Life 2 and my computer just dies like there had been a power outage. There's no problems with the power or cables etc, but the system now won't power up. The PSU makes a clicking sound and the power light on the case flashes for a 1/2 second but thats it. I removed all the components one by one with no joy until I took out my graphics card (GeForce 6800) and then it all came to life. I'm not even sure whether it posted though because there was no video signal (obviously). My thoughts were a power supply problem? Its an 'Eagle' 350w (came with the case). I always thought 350w was a little underpowered and the fact the system died at a time of high power drain makes me think the PSU has died. Well, the 12v line anyway. Another brief thought is my RAM. I bought DDR 400 ram even though my mobo only unofficially supported it. It crashed in games so i clocked it down to 333 levels and everything worked stable. However from time to time the bios would seem to forget i had underclocked the RAM and put it back up to full tilt. Again the system would crash and i would change the settings. Is it possible this time it just fried the RAM or mobo? Here's the rest of my specs: p4 2.4ghz MSI 648max 1gb ddr 400 ram geforce 6800 wd 40gb hd maxtor 60gb hd sb audigy Any advice would be very appreciated!
