Monitor about to die?

I'm not entirely certain what's wrong with my computer monitor, if anything at all. Allow me to explain:

Yesterday, I powered my computer up from sleep mode to find that the monitor was not on. I tried turning it on, but nothing. Not even an amber light signifying that it had power but no signal. Eventually after some fiddling I found that unplugging the power cord for 15+ seconds and then plugging it back in, the monitor once again powered on as the blue light came on. While this was happening, I was booting my computer up again. No further problems all day long.

Today, I come once again to fire up the computer from sleep mode, and the monitor was having the same problem. Only this time, no amount of resetting it by taking out the power chord would fix it. It will turn on, then immediately turn off and refuse to turn back on. Unless however, I am at the boot menu, in which case it has no problems. But trying to Start Windows Normally would cause the monitor to completely power off the second it reached the user login screen and revert to the same problem.

Eventually I got Startup Repair at the boot menu and the monitor held out for that. I've since used system restore, but I'm not certain what it might be. It could be that the monitor finally just decided to work again, like yesterday. OR it could be that system restoring fixed it, but I'm not so sure.

Anyone have any idea? It's not a signal issue, if it was I'd be getting the blue light turning amber. What's going on is the monitor is completely and utterly powering itself off and refusing to power up again barring the method with the power chord I described earlier.

Your monitor is probably dying but it could also be an issue with the graphics card or even the PSU. If you have acccess to another PC I would suggest swapping the monitors and seeing if this still happens.

Also, does this also happen when you shut down the computer from the Start Menu? Sometimes Windows doesn't send the correct "wake up" signal when resuming from sleep, or the monitor doesn't recognise it. If the monitor works in that circumstance, I would suggest turning off power saving (you will find the settings under Control Panel), at least until figure out if it's a problem with the monitor, or something else.
