So, I wanted to replace the thermal paste on my ancient pc. Everything went fine but when I turned the pc on, everything seemed fine and the windows logo came up but after that I my monitor said no signal and the screen was black. I can’t boot into safe mode because for some reason when I spam f8 and shift it just goes straight to the windows logo. And now I have no idea what to do. And also I may have accidentally dropped my screwdriver onto my motherboard.
