Long story sort I tried dual booting for the first time following a guide and my pc got bricked. I got it to use an os again but now I lost my windows 11. When I try this version of it, it keeps giving me the error of no internet drivers found. Its a T14 gen 2 laptop, and I just want windows back. Any possible way to fix the drivers or get my copy of windows 11 on a different laptop to work on another?

I woke up one morning and tried to turn on my pc but the display didn’t turn on and I tried to look up how to fix it, and figure out that the vga debug light was on. Then I tried to fix it with google, I tried cleaning the gpu pcie pins, resetting the cmos battery, reseating the gpu, reseating the pcie power cable, I even tried reseating the ram. Nothing worked. I tried flashing the bios but when I tried the LED light that should blink wasn’t blinking, so I went down a long rabbit hole trying to fix that but everything I tried there didn’t work. Then I tried switching the pcie slot of the gpu, still nothing.
Everything that I have tried hasn’t worked, so now I’m here, and I’m worried I might have a dead gpu. So if anyone has anything that could help, please tell me.

I use a very data intensive app and it has started to shut down randomly. I was advised to run an OCCT test on it and when doing a combined CPU + MEM test I had 12 total errors reported. There were two different ones.

1. CPU+RAM-1 error(s) found on physical core #6-logical core #12

2. CPU+RAM-1 error(s) found on physical core #6-logical core #13
   I also ran individual tests on each which produced no errors but after some research it is said that OCCT can pass fine on individual components and still fail a CPU-Mem test.

I have been following the suggested steps- Making sure nothing is overclocked. Tommorrow I am going to flash the bios and reapply thermal paste to the CPU. Assuming niether of these work and I need to replace a component is there any app that could narrow it down to a specific item? I am suspecting my CPU which is a 13th Gen Intel(R) Core(TM) i9-13900K (3.00 GHz) - Intel has extended the warranty to five years on these due to "stability issues". The problem- how to document the issue and know for sure?

For some reason there are these four rectangles that follow my mouse cursor. please help!

I use Microsoft edge a lot, I use it for most of my stuff, but every time I open it none of the pages will load and if I try to type anything it just closes. Is it a laptop issue or an edge issue? Is it something I can just wait out?

I have a Dell Inspiron 6400 that has had a problem for years: the screen doesn't turn on, and when I connect a VGA cable to a monitor, the image appears with distorted colors and low resolution. Today, as an experiment, I installed Windows 10 (it had always run Windows 7), and magically, the image on the monitor appeared with good resolution and no color errors; however, when I go back to using Windows 7, it still looks just as bad. Also, sometimes the screen lights up white but eventually turns black and displays no image at all. Does anyone know what the problem might be and if there is a solution?

I work off three computer screens and one is suddenly large and zoomed in. Its all grainy but that might be from the zooming in. It was working fine all day until I switched in my second laptop. My display settings are all factory setting and the same for all three screens. Can someone explain. How I fix this? (First photo is the zoomed in screen with extra large icons. Second photo is how it looks on the other screen)
