GeForce RTX 5070 Ti Black Screens

[Velvis]

A friend built/setup a brand new gaming computer. Said it worked fine for a day then He said a game (I think Battlefield 6) required secure boot to be shut off to work so he went into the BIOS and did so. Afterwards after a few minutes the computer would display a black screen just running Windows (but the computer seems to be still running).

I havent be able to get more than a minute or so before the screen goes black.
I also booted into BIOS and after about 30-60 seconds the screen goes black.

I removed the GeForce card and just plugged into the built in HDMI video and it has been running without issue.
I am not convinced the secure boot has anything to do with it.

What are the reasons a GeForce card would/could cause black screens just 30-60 seconds into Windows.

Gaming rigs aren't really in my wheelhouse but wanted to help a friend out if I can.

If it happens in BIOS too, I'd say it's most likely a defective video card. Try the card in a different computer and see if the problem follows it.

BF6 requires TPM/Secure Boot why did the user disable the feature for? Main issue of a fault would be drivers, have you done a removal of drivers with DDU, shut down method? As to what you are describing sounds like a commond TDR Error (Time Delay Response) of card & drivers within Windows.

My Checklist would be -

- Intitiate a CMOS reset on the board to set CMOS back to it's default state.
- Reseat GPU, RAM, and Flush PSU/Board Power
- Check CPU temp in BIOS for a min or two to check thermals out of windows
- DDU Current GFX Driver Set
- Reinstall GFX Drivers


AS @backwoodsman stated, try another card to see if there is an issue and check the Event Viewer and post any errors up here.
