I have been having issues with computer such as programs crashing occasional bsod, 3-4 months ago had problems with windows sayin it wasn't genuine(it is, I bought it with computer) now for a while it wont run windows update(I checked on microsoft website and tried a few thing, Nothing works. Also windows defender won't update.
So I backed up all my files to external hd, popped in win 7 cd tried to start fresh and it gives me bsod every time. Now I am wondering if its a hardware issue. I tried changing settings on bios to default and then back.
