Help please i cant open anything related to my settings

So i recently got more RAM for my computer and decided to put it in. Well i had an old Wi-Fi card i used to use, but didn't work so i thought to try it again since my computer case was open and it wouldn't hurt. After i put it in my computer it went blue screen and i took it out. After that i booted up my computer and i couldn't open my windows or the search bar next to it, my audio is gone and there are no options for it either. i cant open any apps related to windows or the window apps. I have tired a lot of things but nothing has worked. Please help me out i can call someone on discord on my phone and show you if need be. THANK YOU GUYS! i would link a video but i cant open the app lol
