Okay every hour or so my computer will decide to lockup or just restart its self. Then when its restarting or i restart it. The windows boot screen just sits there loading forever not doing nothing and if I leave it long enough sometimes a brief blue screen appears which ive seen the main words for about a second and it said registry error. Im running a 2.0 Ghz Dual Core with 1 gb ram 450 W power supply NVIDA motherboard with a Geforce 512mb video card. I have 2 fans running so i know its not a temperature problem cause ive looked in BIOS and nothing in there is out of the ordinary. Please im in distress I need to get this computer stable and running. Just bought it a few months ago don’t want to actually get rid of it yet.
