Tech Help computer keeps crashing

[Jr32]

So I just bought an m.2 1tb SSD and I've been told I could boot windows faster and everything else if I put windows on an M.2 I watched videos on how to do that, then reinstalled windows onto the m.2, before I did any of that my pc was running fine just very laggy and slow so I just decided while I'm reinstalling windows why not just full restart the computer again to make it faster again and download what I really used, So I did all of that, and then for some reason it wasn't working letting me put windows on the m.2 it didn't even let me open the removable drive with windows in it. It kept crashing and then so I just decided to fully restart it and after fully restarting it, It let me reinstall windows I did that, then problems started happening I downloaded most of my stuff back and just played some games and I had a removable hard drive that I put my old downloads and stuff that I wanted to keep I plugged it back in and grabbed whatever was in the drive and dragged it into the downloads folder. Then for some reason my windows kept crashing and saying something happened and then the pc would restart and whenever it restarts the fan go at high speeds and it just stayed at that nothing popping up on the screen, so then I noticed whenever the pc turned on there would be an orange dram light that would pop up then after a red cpu light then green for boot, Now every time it crashes I have to fully restart my computer can't play games or do school work cause it keeps saying there's a problem, so I have to fully restart and reinstall windows every time I've been searching up the stop codes that pop up but its a new thing every time and nothing is working I don't know what else to do so I'm posting this to see if anyone has to same problems or knows how to help me I just want to be able to use my computer again everything is basically new and all the things I searched up are saying that I need a new motherboard or new psu but all the money went into the pc so I'm hoping there's nothing wrong with anything and that there's a way to fix it by just playing with some files or commands. Please someone help me.

If anybody that can help needs more information I'll try my best to explain everything that's going on with the pc I can explain to the best of my ability, I just want my computer fixed after spending so much money on it and don't wanna pay someone else hundreds of dollars to look at it and not know anything, Its been stressful without a computer especially during online class, so any help will be nice.
