Computer shows black screen with words on startup

[sanjae101]

my computer (windows vista) shows a black screen with words on start-up and at the bottom, it requires me to press F1 key to reboot, and F2 key to set up (i never know what to do when i press F2, i just press F1 to reboot. it also takes a long while to boot up.)

these messages are from the system bios before windows even begins to load. You should read what the text says. it may be that your cmos battery needs to be replaced.
