I recently had some malware issues and (long story short) have decided to re-install my operating system (win7 64-bit). However, when I try to boot from the installation disc, I run into an issue. I get to the "press any key to boot from disc" option, but even after I press a key nothing happens. I know the keyboard is on because it is lit up. I checked the USB configuration in the BIOS and all the options are enabled. I'm stumped. Any ideas?
