black screen when booting

[Joseph777]

Hello,

This is my first post here. This computer of mine if you go into the bios has an option to turn up the proccessor speed and I did and now when I tried to restart the computer nothing happens. Just black screen. Any ideas would be greatly appreciated.

You should NOT play with things you don't understand. You will need to remove the CMOS battery on the motherboard (flat and about the size of a nickel) for 10 minutes or so and then replace it to reset the defaults. Be sure and unplug the computer first.
