Laptop cannot boot or install windows I have used this device for 8yrs

I got it to work, and your answer didn’t help at all. The computer ignores every disc I try to use and bios has a password set that I didn’t change and will not boot into anything. As soon as the windows logo appears on the screen, the computer goes into a black screen. There is no way to change anything from what you said. I had to modify the motherboard to even get a blue screen instead of black. System repair does not work, and instantly responds when I do a scan by telling me that it can’t fix my PC. This happened after It crashed several times without BSOD. It will not give me the menu, but it will show the bios menu. I had to change the settings about how it reads data to get it to read a USB. I used windows to install USB and now it works! It’s for sale/trade on the Facebook marketplace. I am not a complete computer expert lol so I made the mistake of formatting EVERY drive like 10 times

After getting it set up though, it performs normally except for odd CPU spikes. Goes from 1-7% CPU usage to 100% thank you for trying to help though! The computer was opened but there was no apparent damage to anything. Still thanks for trying to help me. The case is solved and if anyone has this issue I will attempt to help you!
