It's actually f1 key for entering bios, sorry .
i recently installed a new motherboard in my computer, an Asus A8AE-LE, the computer is an old Compaq Presario. It booted up fine and everything seems to be working with two exceptions. The first is, I cant get into my bios settings using the f2 key like I'm supposed to, it just does nothing. The second is I'm getting an error on startup,"system fan has failed" even though the fan is working. Any suggestions ?
