I have a Emachine W4885, 2.8MHz, 512RAM. Anyways, I'm booting up my computer, the monitor acts like it's in stanby mode as it boots up and I see nothing, just a black screen. When the monitor fades on, I see the windows user login screen. How do I access my bios as my computer is starting up? I've tried the DEL key, it's used for Emachines. Could it be the monitor?
