SOURCE: Monitor malfunction, says VGA Input: No Signal and goes to sleep
If it was your video card, you would have no picture at all. Try to boot in safe mode and do into your options and make sure your hibernation is not on. Only other thing I can think of, it could be *********** board.
SOURCE: cpu says no input vga signal, then goes to sleep
The no input VGA signal just means that the monitor is not receiving anything from the graphic card on the tower. Is the card a digital (DVI) output card? You'll know by the connector, it's white and slightly wider than a standard VGA connector. If so, perhaps the monitor is set to the wrong input?
If that isn't the case, and the computer is using an on-board or built-in graphics controller, you could try resetting the system's CMOS settings by setting the clear-settings jumper on the system board, or simply remove the plug and CMOS battery for a few minutes. Check the computer's documentation on the exact steps to do this.
Hope this helps!

Sounds like the motherboard might be bad but go thru these steps.
Unseat and reseat the memory one stick at a time in each slot one at at time and turn on the computer after each stick reinsertion.
If that doesn't get the video to come back up then go ahead and unseat and reseat the CPU. Then try turning on the computer.
If that doesn't do it, make sure there is no power going to the hard drive or the dvd drive. Then try turning on the computer.
If you do all of these steps and you still have no video, then the motherboard is bad and would need to be replaced.

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)
