I know my power supply sucks balls. It's a 300w w/ 10A on the 12v rail. But I was burning a DVD and watched the used read buffer decreace about 1/10'th the way in burn. Then pc restarted itself. Then tried booting off the now ruined dvd, even though the hdd is first in line... wtf?? I have p4 2.8ghz 533fsb 1mb l2 socket 478 prescott... 2x512 crucial ballstix ddr400 Some intel mobo I forget what it is, 20 pin & 4 pin... Nvidia GeForce FX 5200 ultra... Got rid of the sound card so onboard sound 1 ATA HDD maxtor 120gb 1dvd-burner drive way too underpowered?
