Unplug everything from the tower. Including power cord.
Press the power button for 5 secs.
Proceed to connect, power line, mouse, keyboard and monitor
That should reset the power or hibernation mode that you might have issues.
If everything looks normal, proceed to connect your remaining devices.
You must be aware that having a BIOS settings to boot from USB, DVD or USB-FLOPPY might prevent to boot into windows.

make sure your monitor is screwd all the way to tower check to see if theres a brake in cord.

If your AOC Monitor's OSD lock
press and hold the Menubutton(for 10sec) while the monitor is off
then press power button to turn the monitor on.

please let me know if doesnt help.

I love this one. I've actually done this many times before and have been successful.

1. Turn the computer off and unplug the power cord from the back of the tower.

2. Press and hold the power button for about 3 seconds while the computer is unplugged (this drains the remaining power from the capacitors on the motherboard).

3. Plug the computer back in and turn it on.

If that does not work, follow steps 1 and 2 again, but this time:

3. Open the computer while it is unplugged and unplug the power supply from the motherboard then hold down the power button again for 3 seconds. (You may also want to take the RAM out and put in back in)

4. Plug everything back in and turn the computer on.

Disconnect all the devices from the computer(tower) including keyboard, mouse, monitor(everything)..even the power cable

Now keep on holding down the power button on the computer tower for 15-30 seconds..

Now release the power button, plug in the power cable, monitor, keyboard, mouse and turn on the computer...

If it works, great!!!

Otherwise, take it for repair..

Hook it up as u would hook up a regular monitor,Turn on the tv power.U the remote see a button said function press it selected PC in.Now u use as a computer monitor.

The interface between the monitor and the cable might need replacement. Please check it.

my moniter was automatic restarted, and osd lock not open,where is is osd open option?

oh no please stop,you do know that Fn-F1 puts the eeepc into sleep mode and Fn-F5 switches from internal to external monitor ,its very easy to hit these hotkeys accidently,im sorry i couldnt have told you this earlier

Your monitor has disco fever and will have to be shot in a midnight ritual in Palm Springs. Or, you will have to replace a diac circuit linking the display, power control, and power supply grounds (or possibly an overvolt protector of some sort in the power supply.) I don't know why for this kind of error the designer couldn't just put a message on the OSD in some random human language.
