I have a Dell Precision 490 5130 2ghz xeon running 64 bit windows 7 pro.
Original hardware: 2Gb pc2 5300 ecc ram, asus 210 silent gpu, 1 TB 7200 rpm SATA HDD, Dvd-rom, DVD-rw, 3.5 fdd.
Awhile back, I installed upgrades for gaming and better performance: 16Gb pc2 6400 ecc ram, asus gtx 950 gpu. It works wonderfully for month. Intermittently, it starts shutting down for no good reason: while I'm playing games, while I'm surfing the web, while I'm doing nothing at all. Eventually it starts shutting down while the os is trying to initialize. I reformat the hd and reinstall windows... Same problem. I reinstall the original hardware... Same problem. I clean the fans and components as best I can... Same problem. I try to boot from windows 7 boot disk... Same problem. I leave the side panel open and point a house fan (on high) directly at the cpu... Same problem. I think the power supply needs to be replaced, but I'd like an expert opinion before I spend more money.
