Hey i need some serious support, i'm totally stuck and have no idea what's going on. While i'm running my computer doing what i do (at the moment it's just some light usage, installing stuff, iTunes, Firefox) and for absolutely no reason whatsoever my system just restarts, black screen and a bleep, just like when i turn my system on normally from an off state. I have write caching disabled as that seems to extend the length of time i can use my computer before a restart. Recently i tried installing Vista Ultimate as well and i got a BSOD every time i tried that, i'll try uploading some minidumps but could someone walk me through how to do it? i'm new to the whole dump thing and stuff. PLEASE HELP I LITERALLY SCREAM EVERY TIME THIS HAPPENS, IT'S DRIVING ME INSANE!
