I recently installed an asus wifi card and started up the computer just fine. The wifi speed was great and I was able to load up some games with my friends. In the middle of the game the computer freezes entirely with no response at all to anything. I waited about 10 minutes and eventually hit the power button. It loads up disk repair twice and now it just tells me to select a boot device or insert boot media. None of the selections work and the bios isnt really helpful.
