external monitor goes black while gaming

[DE00]

Yes i have installed latest drivers for both the display and GPU... The issue I have is sometimes, while gaming and not always consistent. the external monitor I play on will go black, still hearing sound, then come back. It isn't just when the machine gets hot, it can happen anytime and only while using the GPU. I am afraid the gpu is going bad but perhapps I am missing somehting. Also I can't install the omen command center because the required bios update keeps failing to load the image. Any ideas on either of these ?s

Try performing a hard reset on the PC and check if it helps.

Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Remove the battery from the battery compartment.
With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.
Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
The computer starts normally or a startup menu opens.
If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.
