Monitor display suddenly turns off, can't get the display back

Tonight I was playing a good old game. I minimized to my desktop while the game was running and pulled open Windows calculator, did some calculator stuff, but then the computer goes into a blue error screen and then restarts. A few moments later, the display on my monitor suddenly turns off as if it were put to sleep. And even if I turn it off cold and restart the computer, nothing appears on the display at all, not even a BIOS logo screen. So weird.

System specs:
AMD E-350 Processor x2 (1.6Ghz)
4GB RAM (upgraded from OEM default 2GB)
500GB Hard Drive
GRAPHICS: AMD Radeon HD 6310
Acer (eMachines)-EL1360G UW12P
bundled with eMachines brand monitor/speakers

You can try:

- Remove the power cord of monitor and PC for a minute. Not just shut down.
- Clear CMOS if you don't mind reconfiguring the BIOS

Also, the computer doesn't make the startup 'beep' sound, it just turns on.

Alright but did you try what was suggested?

I will do that later.

Alright I tried the unplug and plug back in but it's still doing three strange thing.

I have no extra monitors. I'm afraid I'm going to need to spend money on a brand new one.

You can just pick the PC up and take to a friend/ neighbor or hook it up to your LCD TV! Before you pay for a monitor you are not even sure is the problem.
