Next time you have this problem don't unplug the power cable just wiggle it back and forth where it plugs in. This is to check if its a poor connection. and or cable.

Try plugging the monitor directly to a wall plug. If that works, move it to the same power strip as your puter. If that works, you may need to investigate a problem in your power supply.

This is probably the longest I've ever had a Windows machine run without having to restore it to scratch. I'm used to restoring to "factory" about every 2 yrs. I've run with Win7 since new in 2009 and only recently (Nov, '14) restored to clean up the machine from all my 'xperimenting. LOL!! I may never need another machine.

Upgraded to 10 when it was still free, then installed 2017 update.
Hi

Just checking but when you say removing the power cable, you are talking about the monitor power cable rather than the PC cable?

Do you have another display to test it on?
It does sound like capacitors are blown in the monitor.
At least that's the only thing I've seen before that caused that behavior where it wasn't the graphics directly.

Yep it sure sounds like a bad monitor plug or broken wire inside the power cable. Could be a bad receptacle too(Wall plug).

Hi

Again to make sure I understand the situation. If you remove the PC power cable and the PC reboots, then the monitor works okay? But if you 'restart' your PC the monitor is blank?

This is crazy, but I do have two question.
1. Is their anything showing up in Device Manger?
2. What happens if you go Start/Shut Down and do a new start. Don't unplug any thing.

1. Is their anything showing up in Device Manger?
2. What happens if you go Start/Shut Down and do a new start. Don't unplug any thing.
1- Device manager just shows yellow icon on high definition audio device because there is some problem with sound too.
2- I will check again what happens if I go to start/shutdown and do new start but as far as I remember monitor on/off blue light keeps on blinking instead of turing to stable blue in normal circumstance when I restart the computer.
The above mentioned problem only occured 2 times in last 2-3 weeks.
