Sounds like a hardware issue to me (or you have a bad copy of Win7, if you want PM me for a MSDN download link) :/
Mac Reviewed by Mac on . PC Seriously messed? So uhm. My pc is dead for a while now. I had vista before, formatted HDD, installed windows 7 64 bit. Now there's where the problems started. After installing I install my wlan adapter (using my CD), ofcourse open IE, and download firefox. Which doesn't work. Nothing I download works, or can install. I just open the .exe/MSI, press yes for the security crap, and after that it either says Firefox has stopped working (APPCRASH), or nothing happens at all. I've formatted over 4 times the past Rating: 5
