So I've had my PC for about two and a half years, and I came back from this month long trip to find that my comp turned on, but my monitor wouldn't respond. When I press the power button on the Acer monitor, it turns on, displays a "No Signal" message, and then turns off. I swapped out the graphics card, the monitor, and the cable, but nothing changed. I took the RAM out and put it back in, still nothing. I tried the method of unplugging the comp and holding down on the power button, no dice. Any ideas?
take the RAM back out and try to boot. Does the PC beep, or give any errors, or does it just sit there? If it just sits there, then the Motherboard is fried!
