I just built myself a new PC with the following specs: Intel Core 2 Duo E7200 OCZ 2GB Pc6400 DDR2 Ram Diamond Radeon Hd3850 factory overclocked to 725/1800 Mhz Gigabyte Ga-EP35-DS3L Antec Earthwatts EA500 500w PSU Samsung 20x DVD burner Western Digital 160GB HD Cooler Master Centurion 5 Case From early on, this build started having troubles. I ran Furmark to stress the GPU, and it crashed almost immediately, with the screen going black with white vertical streaks. I had to resort to lowering the clocks back to the standard ones in order to get it stable. I decided to install Windows XP SP3, just to keep everything up to date. During the reboot, however, the PC locked up at the Gigabyte splash/logo screen. I tried pressing Del to enter the BIOS, but nothing happened. I had to reset the CMOS in order to get everything back to normal again. This anomaly came back again, however, and I was puzzled. I then noticed that if I unplugged my Ipod charger when the PC froze at the splash screen, the computer would boot up normally. This indicated to me that my PSU was having issues. My games also crash at certain times, possibly due to the video card not getting enough power. Could the PSU be the culprit for the aforementioned issues? Or is it something else?
