So i got a dell xps 400. Last week i did some up grades with a new processor ram and video card all within capable specs of the system. was working fine then yesterday i spent 5 hours playing on it and now the windows system wont start. Ran a repair and nothing. Currently runing a utility check of the hardware but wont know results tell i get off duty. Last check there were no viruses and the regestry was keep clean and in check. no spamware or adware either.
