Trouble with Windows 10 Installation and Blue Screens

Hey everyone! I recently built my first PC, and I've run into some issues while trying to install an operating system. After struggling for about a week with Windows 11 (couldn't get it installed at all), I decided to go with Windows 10, which surprisingly installed without any problems. I got my drivers set up, and everything seemed fine until I was downloading a DODI repack and chatting on Discord. Suddenly, I hit a blue screen error related to memory management. After it rebooted, Windows loaded but was incredibly slow. I couldn't open anything, and it felt really off. When I powered it down and turned it back on, it went straight into the BIOS, which didn't recognize a boot drive, although it did detect my SSD. It was like Windows disappeared! I'm suspecting it might be an issue with the RAM since I set it to 3200MHz in the BIOS, but it was initially at 2400MHz. I'm really interested to hear your thoughts on this. Please ask anything that might help!
