Windows 10 to 11 boot

Several days ago I downloaded the most recent updates for windows 10. At the same time I installed a new GPU (5070ti). The next day I noticed RGB flickering of colors on my display. I redownloaded the drivers for GPU. It seemed to have worked. The next day I turned on my display and it looked bad. So I shut off my PC went to turn it on, and it wouldn’t boot. I looked at my motherboard, and the DRAM light was on. I moved the DRAM to alternate slots. And it worked. But then in UEFI BIOS, all of my disk had disappeared, including my BOOT drive. So I took out the 5070ti, put back in my RX580 and my BOOT drive reappeared along with all the disk. At this point I attempted to boot, but it would make it to the windows password screen and then (bsod) blue screen of death on me. After several attempts I never made it back to the password screen. I attempted to repair and wipe, it said it could not. I attempted to run through the menu of 9 options open command prompt, none of them worked. 
So I decided to buy Windows 11 and start with a fresh boot drive to wipe everything, and start fresh. I chose my disk, and then about 30% in got an error code blue screen, I tried a different disk, made it to 70% error code blue screen again! Tried the repair feature, went into command prompt that way which did work, and ran disk scan and scan the whole pc which it said it did repair, and I turned off and rebooted to which it still didn’t work. Which is where I’m at now. I tried calling Microsoft support and they hung up on me twice. Any help would be appreciated. I also tried rolling back updates, it won’t let me do that either.

thank you for any help
