[Harvygr8]

Hello, when I boot up windows it shows desktop for 5 seconds and suddenly shows a pink solid background like my desktop wallpaper and stays there I can’t do anything , tried resetting windows and replugging gpu cables , any solution?
Is this a gpu issue ??? Because it was working fine before

at the login screen, click on the power button in bottom right of screen
while holding shift, click restart
that loads windows into a blue menu at startup

lets see what safe mode looks like
choose troubleshoot
choose advanced
choose start up options
click the restart button
choose a safe mode (it doesn't matter which) by using number associated with it.
Pc will restart and load safe mode

if its a driver or program causing it, screen should be normal here.. is it?

Curious what it is like in a clean boot - you can do this from within safe mode
make sure to read instructions and make sure NOT to disable any microsoft services or windows won't load right - https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows

if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.

a reset should have fixed it if it was a driver... also if it was a startup program.
