Hello All,


I have an issue that is driving me mad.


Recently my Windows 8.1 pc stopped showing video during POST (no signal to screen).

The signal is fine once the Win login screen loads.

As a result I am unable to see what I am doing in BIOS.


This has been happening for a few days now. I have updated to the latest driver (not sure if that could effect video during POST though), no change. Tried a different HDMI cord out of desperation.


The PC is:


Win 8.1 Pro 64

Core i7 4790


256GB SSD (OS etc)

2x2TB HD



Thanks in advance for any attention to this problem!

Have you tried dropping back to the default VGA mode for the video?

Hi Dick,


I have tried using the onboard HDMI port, instead of the graphics card's, but still no video signal in POST/BIOS.

Do you suggest lowering the resolution? My card is outputting at 1920x1080 which is the native resolution for my monitor.


Thanks for the help, any suggestions are welcome
