I'm starting to go nuts with my computer, I really have no idea what is making it so unstable. It's a 1.6a/asus p4b266-c, 256mb samsung pc2700, MSI geforce 4 ti4200, Enermax 303. The Temps are not the problem, under idle/light use they stay in celsius the 30's and under max have never gone past the high 40's. I can't see the power supply being the problem, I have monitored the voltages in 1 second intervals and it has never gone out of spec when it crashes or screws up. I really don't know what else I can do...please help out I'm already starting to regret upgrading my computer. It will crash in Internet explorer, games, the video goes blank and I get green lines at the top, it will shutout out of nowhere like it has gone into sleep mode, It has restarted by itself, and this all happens without anything overclocked. I've been running it at stock speeds but it's no better then if I run it overclocked. Please give me suggestions I don't think I can take this anymore.
