I've had this build for about 4 years now and haven't had many problems. Everything was working fine last night (was gaming) and upon waking up and trying to boot up my computer the monitor wouldn't turn on. Everything is plugged in correctly as I haven't made any changes. The CPU fan, computer fan, DVD drive, and GPU fan all turn on and I see my LED lights turn on as well. The monitor says "no signal". I've read that removing the CMOS battery from the motherboard could help in all else fails. Any ideas?

I'd recommend changing the monitor cable to see if that helps. Most of the time that happens to me its usually just a bad one.

Try removing your graphic card and using the integrated graphics option if your motherboard supports it. Are you using HDMI/DVI/VGA/Digital?
Check to see if the monitor detects another machine as well.

I noticed that for the part that plugs into the computer for the monitor one of the pins is pushed in more than the others. Should I buy a new cable or just another HDMI part?

Cables are cheap as dirt. You can head over to Amazon or Newegg and purchase an HDMI cable and a DVI cable for just about tree fiddy ($3.50). If they don't work then it wasn't such a huge investment and you'd have extra cables for later use.

On another note, I'd try plugging in a differt TV or monitor into that same exact port on the GPU itself that the current non functional monitor is plugged into to see if it's operational.

Now try it with a different cable but on the same port to your TV or monitor. (This is starting to twist my tongue) If that doesn't work still then I'd try another port. If it still doesn't work, then I'd contact your GPU vendor (although your warranty may be up by now) and try to ask for a replacement. It's not unheard of for some ports to die on a GPU. After over a year of ownership my top DVI port failed on my card.

Here are two checklists on no video output. Have you tried reseating the RAM (remove each stick, clean the contacts, blow out the slot, and then reinstall)? You can also do the same with the graphics card.

Have you checked that the correct video input is selected within the monitor menus?
Have you tried resetting the monitor by unplugging the monitor for thirty seconds? Then reboot after you have plugged the monitor back in.

I'm gonna pick up a new VGA cable later today and try that before trying any of the other steps. I'll post in this thread to update whether the problem was resolved.
