Having issues with zoom levels on any browser, caused pc to become bricked

Hi,

I have had my PC for a good few years now. Ive had issues with it in the past, which took some figuring out to resolve, but this is one that has me stumped.

I recently moved house, and of course brought my PC with me. I had to get a new monitor, wireless mouse, and even a PCIe wifi card, but other than that its all the exact same as it was before. So I get it set up, the monitor has a couple teething problems which I resolve fairly quickly, but as soon as I get onto my default web browser, it happens - the thing begins zooming itself in and out. Infrequently, but often.

Naturally, I begin the process of troubleshooting, but all the things I try have no effect on this weird issue. Ive tried:

• disconnecting the keyboard
• disconnecting the mouse, both from its wireless adapter and by turning it off
• disconnecting the new monitor
• connecting the new monitor to a different system - it worked perfectly
• restarting my pc, multiple times
• changing pc settings, including the refresh rate, the resolution, the default scale, automatic scaling, etc
• changing browser, it does this on Firefox, Chrome and Edge
• changing browser settings related to scaling

I had come across another post from 2021 that seemed to have had a similar issue, after going through all of these things, and decided to give the solution a go. It said to go into msconfig and adjust the startup programs to remove anything that isnt necessary to the computer, that might be causing the issue. I followed the steps, including making sure all base Microsoft programs remained active, and now my problem has gone beyond a simple scaling issue. My pc is now stuck in a loop of trying to restart, and im scared it may be unfixable. Im only able to get to the BIOS screen and the Windows Recovery screen.

Can anyone help me with this?
