|What I meant was, if it was a driver issue you could probably boot to safe mode. Since you can't--because nothing shows on the screen--it's not drivers. Well, unless you have an old CRT monitor and it's booting so quick it's passing the posting screen before the monitor warms up. If that were the case you could still use F8 to bring up the boot menu and choose the safe mode option. By the time you did that the monitor should be able to display the page.|
Does the computer give any beeps when you start it up?
Sometimes you can try clearing the cmos. I don't know why but sometimes that does it. To do that you open the case and with the power cord removed, move the jumper to the 'clear' position for a few seconds and then back to the standby position. You may need to check its manual if you can't locate the jumpers on the motherboard.

There's some suggestions here too:
