tell me if there is something i need to know like: what were the things that you've doing with your computer before the problem happened?? are there any recent hardware/software changes?? tell also your OS- is it XP or Vista...
first, let's try to check if the problem is with the monitor or not,okey? try unplugging the monitor blue connector at the back of the tower.and make sure that your monitor is turned-on.If you can see a colored bars displayed.you monitor is okey.if not, try a known good monitor...if it woks the problem is with the old monitor.(resolved)
2 (if not)
Now, complelely turn off your computer and try reseating all the cables, and your hardware components such as memory,video card,IDE cable and so on. but before doing so, unplug the power cable and then push the power button to drain the power.after reseating everything, plug back the power cable and turn on computer.try listening to the tower,tell me if you can hear some beeps also.
if no video issue is still there, try putting a known good video card if you have any.if a known good video card works then the problem is with the old one..
if the problem is still there after everything that you've done try calling the manufacturer. this is lead to a motherboard problem but try to call them first.

There are a couple things that you need to look at. The first is your power supply. I've had computers seeming to run fine with no video. Turned out to be bad power supplies.
Does your video card require a power connection? Many high-end video cards need an external power connection. If the card has a power connection, use it.
Have you gone in and checked the cmos settings? What does it say (if anything) for the default video?
Now remove all connections to drives (hard drive and CD and try for video. Try it.
Next, if possible, swap out memory.
After you've tried everything (including maybe burning incense), time to try a new motherboard.

sometimes pulling the power cord out of the pc and then replugging it will let it reboot. for some reason these machines die, and they will not reboot until you take all the power off the motherboard for about 10 seconds.
