odd post/bios screen, plus no keyboard detected @ post

i had recently built a new computer. after installing windows 7 everything was fine, except for during start-up it'd say 'no keyboard deteced'. which it wasn't detecting it because i couldnt acess bios during this. once i came to the windows log in screen, it was then reading the keyboard.

a few days ago i had a power outage during a thunderstorm and now a screen appears when turning on my computer giving me 2 options somehwat like 'continue start up' and 'enter a set up'. these are extremely general ideas of what it says but its not the usual 'start windows normally' screen. i would look but i'm currently at work since i cannot access the internet at home due to these problems lol.

the problem with this screen appearing is that since it is not detecting my keyboard at post, i have no where else to go. i've tried every usb port, as well as a ps/2 keyboard.

i either a. need to figure out how to get past this screen or not have it appear at all or b. figure out how to get it to detect my keyboard.

if you have any suggestions or info i'd really appreciate the help.

thanks.

you could try removing the CMOS battery on the motherboard and using the jumper to reset the BIOS to factory defaults.

Always us a known good PS/2 keyboard. USB is OK after you have everything setup but unless you enable Legacy USB support in the BIOS the USB keyboard may not be seen by the BIOS (I've had this exact problem).

If the PS/2 keyboard is not seen when plugged into the keyboard PS/2 port move it to the PS/2 mouse port.

ok that sounds good. someone else recommended the cmos restart but i didn't know to remove the battery AND hit the jumper. do i hit the jumper before i remove the battery, after, or when i reinstall the battery?

Usually all you have to do is move the jumper to the CLEAR position. Removing the battery is just another way to reset it so doing both should put everything back to default.

Best to read the manual.
