PANIC

What the hell is this la. I just bought a com on friday Practically installed nothing but itunes and transfered one or two games over to the com. The com had a screwed problem la. "ERROR" THE Blue screen. WTF? the games did not cause ny problems on my laptop whichever. Furthermore, i used MCFEE to check for viruses. Clearly, there were none. Which computer causes problems 2 days after purchase? thoughts are running through my head now. Could the virus have missed out on the possibility that the games i transfered contained viruses? Could the games EVEN have VIRUSES? Damn. I feel like a dick. I'm panicking. The com cant function properly now. I cant even start windows up. I need help.
