Disclaimer: Boring Troubleshooting Suggestion Video for newer Windows 8 machines
If you were running a windows 8 machine you bought from a manufacturer like Dell, Lenovo, HP, Acer, or Gateway and you decided to change the video card. When you booted your computer it may have a problem where the bios or boot screen is not showing on your monitor.
One of the most common problems is a bios setting that is preventing the video card from being recognized at startup.
Unfortunately, you’ll need to remove your video card, then boot up your computer into bios, and then possibly disable a few features.
In Lenovo desktops, near the screen where you need to save your bios settings, there is an option “OS Optimized Defaults”. If you disable this feature, you will then be able to see the bios screen when you boot up with the new video card.
If you’re experienced in installing video cards (sort of like me), you might have recently installed a video card into a recent pre-built system like a dell, lenovo, or HP (typically running windows 8). If for some strange reason it’s not working, then you can check the following BIOS options:
Please boot into bios (with graphics card removed) and check for the following:
UEFI or CSM or Secure Boot
Again, please remember to check the basics before you try this:
1) Check to see that BIOS is set to run from PCI express slot
2) Check that video card is properly seated onto motherboard
3) Check to see that power connectors are attached to video card if video card requires additional power
4) Update BIOS if possible
Sorry, I wish I could provide video of me changing this BIOS setting, but all of my computers are old and don’t have this option. Good Luck!
