Windows 10: After awake my PC from sleep... Both Monitors show No Signal, but PC L

After awake my PC from sleep... Both Monitors show No Signal, but PC LEDs are ON, and PC is working, and also CDROM drive can ejected... I use hard shutdown [5-sec press ON button] and restarted OK... what the reason of this? the graphics card?

Monitor says no signal after game install

I have just installed Micro Machines V4. It installed fine and then asked for a restart. I did this and at power up, my PC turned on but there was 'no signal' to the monitor. After it searches for the signals in the monitor settings, the monitor goes to
sleep. I use both a Mac and PC on the same monitor with a Sherwood switch box using HDMI ins and outs. My Mac is powering up fine with the monitor. No issue there. Just not with the PC. I have tried PC to monitor directly using the motherboard HDMI ports.
Have tried VGA from PC to monitor. Same result. Have tried DVI from PC to monitor. Same result. No signals from any.

My setup is ASROCK Z77 Extreme 4

16 Gigs of Ram

Samsung Evo 500G SSD(Boot Drive)

Intel 160G SSD(I installed the game on this drive)

(2) EVGA GEFORCE GTX 660 with SLI Bridge

HP 2711x monitor

Any help would be greatly appreciated. Thank you.

 

PC wakes up without intervention when in sleep mode.

After my PC goes into sleep mode, it awakes without any command from me. Is there a fix for this?

 

Hi lse123

When did this start? Has Windows recently updated drivers?

If you disconnect both monitors and then plug one back in does the monitor wake up ?

Your spec says Win 8.1, are you on 10?

What are you connecting your monitors to, integrated display ports, expansion card? (Models)

Have you tried upgrading or rolling back display driver?
