This sounds like a video card driver issue or the card it self. Make sure all cables are plugged in snug. Once done try to boot in to safe mode by restarting the computer and while it is starting keep on tapping key F8 and choose safe mode. If this works it is driver issue. If nothing happens it is the card it self. Might have to take it to a authorized repair shop. Hope this helps.

SOURCE: I turn my computer on
May be in "RAM". Did you tried by removing the RAM. If not try this remove the RAM and wipe up the dust and fit it again.
And If you do not get the single initial beep, that means the motherboard is not working and that's why you don't get a display. No initial (POST) beep indicates a hardware problem, usually (but not always) with the power supply or motherboard.
All the Best!

Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

There is no signal coming from your PC.
excuse some of the solutions as sounding dumb, but we have to explore all possibilities.
Check the power cable going into the computer
Check the power input disconnect switch on the back of the power supply and make sure it is on
If the pc is plugged into a power bar, make sure it is turned on and the breaker isn't tripped
press power on the PC and make sure the lights are coming on.
now for the solutions that may actually help.
disconnect the power from the PC
if the video is on a card, remove and re-seat the video card
hook the power back up, connect the monitor and try again.
the CMOS on the computer may need to be reset.
I hate totally clearing the CMOS, so what I usually do is remove 1 stick of ram and power up. If the system is alive again, power down, put the RAM back in and power back up.
If that doesn't work, turn the system off, put the CMOS jumper to the CLEAR position for 15 seconds, put it back to the Normal position and then power back up.
Basically, if the monitor works on your friends system but not on yours, the the problem is your system, not the monitor (assuming it isn't working fine til it gets into windows...if that's the problem, you have a driver or configuration problem)
