No Boot and a FLashing Blank Screen

[Sjnovo923]

I have a computer that just won't boot. The Screen is telling me that there is no input signal and the hard drive does sound like it is spinning. All I get is a flashing screen saying no input. Man I hate that screen. So I swap the monitor with a few different ones. I also checked the CPU to make sure that it was installed correctly. I think that it might be a faulty M/B. What does it sound like to you? Any help or insight would be greatly appreciated.
Thanks

You didn't mention any error beeps from the speaker, so we'll assume there weren't any.

PSU is obviously running as you can hear the hard disk revolving. Are the l.e.d.s lit on the front of the case. If not, then it suggests either partially faulty PSU, CPU or mobo kaput.

You could try removing all "unnecessary" add-in cards, i.e. everything except the video card, and see if that helps. Also, remove the video card and firmly re-seat it.

Unlikely, but the CMOS could be corrupted. Remove the battery or move the CMOS jumper to clear - this will of course restore the BIOS to its default and lose all your CMOS settings.

Good luck!
