I purchased las t April a Gateway DX 4850-57 desktop. It ran fine for a few months then a problem starting emerging. After an overnight period the computer would not boot after the Gateway splash screen. This an intermittent problem usually occurring after long periods of shutdown. Contacting Gateway Tech Support, I was advised to reinstall back to the factory default which I did this, they assured me would cure the problem. The next morning came sure enough again the computer would not boot. I tried re-seating all 4 2 gig Sim cards, and I did another reinstall and only added Norton Anti-Virus and Google Chrome no other programs were installed, this to eliminate possible startup issues. I was wondering if it might be the power supply. The computer only came with a 300 watt power supply and it has a dedicated 1 Gig video card albeit not the greatest. Doesanyone have any idea of what may be the problem?
