Windows 10: Disabled graphics card - PC will not boot - or if it does, I cannot see it

Windows 11 Professional, Brand new Thinkstation P360 Ultra with i9 12900 and Intel 770 UHD and Nvidia T400 4gb GPU.While trying to channel video graphics to my Nvidia T400 4GB processor instead of the default Intel GPU, I disabled the Intel 770. Immediately, the screen went black. Now I've spent the last few hours trying to re-boot in safe mode blue screen so I can see the monitor. Monitors show no graphics whatsoever. Nothing seems to be working. Screenshot is just black.

graphics card problems

Hi,

Your computer makes a noise or beeps from your internal speaker because it failed to detect the graphics card. What we can suggest is for you to try cleaning your graphics card with a pencil eraser. Here are the steps below:

• Turn your computer off.
• Pull out your video/graphics card.
• Rubbed the cold contacts with soft pencil eraser.
• Connect your video/graphics card back to the computer.

Kindly note that this is just a temporary fix. If the case still continues, I suggest that you contact your graphics card's manufacturer.

Let us know how it goes.

 

PC slow with new graphics card

In an attempt to upgrade my old PC, I replaced my Geforce 9800 GT graphics card with a new Radeon RX580 graphics card. Unfortunately, with the new graphics card installed and my old graphics card removed, my PC takes 10 minutes to boot. Task manager shows
a high percentage of system interrupts after I login and my PC is too slow to use.

Interestingly, if my old and new graphics cards are installed, my problem completely goes away. I could just leave both graphics cards installed and disable my old card, but I'd really like to remove my old card to give my new card more
breathing space inside my case.

How do I make my PC responsive with my old graphics card removed and my new graphics card installed?

I've tried the following:

1. Used Display Driver Uninstaller to remove my old display drivers.
2. Physically disconnected all non-essential devices.
3. Used device manager to disable all non-essential devices.
4. Updated all drivers.
5. Used dsim and sfc /scannow to repair corrupt files (no corruptions found).
6. Used Microsoft Windows Performance Analyser to create an ETL file.

PC specs:

• Gigabyte ga-ud5-ex58 motherboard with F13 BIOS (latest version).
• Intel i7 920 CPU.
• 32GB RAM.
• Samsung SSD.
• Geforce 9800 GT graphics card.
• Windows 10.
