Hey I downloaded a product from the internet I guess it had a virus in it. After fully downloading it. It gave me a blue screen and when I re booted my pc it came up with this msg "AMD Data change . . .Update new data to DMI!. I have looked around the net abit on my iPad but none of the advice has helped. I enabled acpi on bios but didnt do anything. My computer is a acerbic aspire X1300 it's just a year old. So can anyone help please??? And thanks
