[SOLVED] I changed Bios settings Legacy to UEFI then my monitor stopped displaying

[Phyneom]

Hey! I have a Lenovo G510 i3 laptop. Because the screen is broken I use it with a monitor by connecting them with VGA. I was intented to play Fallout: New Vegas. When I looked at to GPU settings of the game I saw there is only one option to select and it is Intel HD Graphics. After that I thought that my actual GPU (AMD Radeon R5 M200) driver was not updated.

Then I wanted to delete my current driver with a some kind of application and download a new one. That app restarted my laptop at safe mode. After that my laptop stopped displaying to my monitor.

Then I somehow got the display back but I got this:

After that I started my laptop with bios to boot it and I think thats where I did the mistake.

I am not into this bios thing so I can not remember the settings completely. I remember that I changed Legacy settings to UEFI based on a friend. In addition there was a setting with a USB word in it. I changed it too because I tried without changing it and it didn’t work.

After all of these changes I got no display on my monitor. There is no image at bios or normal start. In short, I think I made horrible mistakes without any knowledge. Please help.

changing settings in the bios that you aren't sure of their purpose is not ideal if you want PC to work.

The UEFI/Legacy change would have stopped windows from booting as the bios is looking for a different set of instructions from the hdd. That shouldn't have stopped it showing BIOS.

did you try

Press small button next to power button when notebook is switched off and you'll see the menu where you can select BIOS.

need to reset bios to defaults, it might help although it might still not display on the monitor.

Open it up and unplug the CMOS battery. Pressing on the OneKey button to drain the charge and then even letting it sit for a few days.
