Hey everyone, I'm new to this fourms. Long time reader first time poster. I bought a new computer, a sony VGC Rb30. It has one gig of ram, 200 gig hard drive, 3 ghz w/ Hyper Threading. For some reason I have had a problem with it since day one, I've formatted it 5 or 6 times because it always encounters a problem after a couple weeks. Now I am just sick of it, it's extremly slow and it's very irritatting. I cant go on msn while downloading something. I cant run any anti virus scan because my computer will restart if I do, same with anti spyware scan. I am in desprate need for help. I have this decent PC going to waste, I cant run many any applications at all... I cant burn a dvd... I cant do anything

....PLEASE HELP!!
