i have a a78nx mobo and i was doing great i got the new power supply like you guys told me and i was playing wow. I loaded up the comp and starting playing wow all of the sudden i get this purple screen with white lines and i dont here my processor fan running. Now i shut down the computer and try and restart but as i do nothing happens. the powersupply is on and i hear things but the processer fan isnt. I didnt know what to do. I turned on my comp about 5 min ago and it starts. Ive have a amd athlon xp2000+ processor and have had it for about 3 years. I dont know what is wrong but now im on and wanna get some answers quick.
