Windows 10: monitor failing to acivate

I’ve started encountering a problem with my desktop PC running windows 10.

I have 2 monitors fed by a GeForce GTX 670 on a Gigabyte GA-Z77X-D3H motherboard with an Intel I 7 3770K chip.

Recently the monitors have failed to display anything when the PC is switched on – not always – but frequently enough recently to raise the alarm that this is a problem.

The PC emits its usual beep but no start up screen or any other sign of boot up occurs with increasing frequency.

I’ve tried booting to ‘safe’ – no effect ; un/replugging the hdmi cables and swapping them over – no effect ; soft rebooting and completely disconnecting from the mains. A total switch off from the manins worked twice but now even that cannot guarantee a cure - the failure rate of booting to a visible desktop is getting greater.

This is a fairly venerable machine built 2012, but has performed as a steady workhorse for years, requiring only a thorough vacuuming some time ago to deal with filth build up on internal fans.

I might add that when as now both displays are on, everything is normal, no shudders, odd noises, nothing suspicious at all.

Before I dismantle things, has anyone a pointer as to the most likely cause of this gremlin?

BTW – 1 further point.

The button battery on the motherboard. If this is replaced and I suspect it’s on its last legs, does it mean that anything has to be reset? Over the years I’ve fitted 3 extra hard drives.

I hate going into BIOS, the Gigabyte GA-Z77X-D3H motherboard display is not a model of clarity and a lot has been lost in translation. If I can get away with not having to navigate the BIOS screen, either in its traditional or Gigabyte’s flaky schematic form, I’d add years to my life.

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Trouble with 2 monitors

Hi Tim,

Thank you for posting your query in Microsoft Community.

I suggest you to change the settings to Extended Monitor and check if it helps.

Please follow below steps:

• Right Click any ware of the Desktop, and launch Personalization.
• Go to dual monitor settings under personalization, and change it Extended Monitor.

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.
