I have a problem where my PC goes to the desktop for a few minutes and then it restarts. I can give the product family. It's Lenovo, c40-05 and I've tried SFC /scannow, so yeah. It goes to a black screen, then lenovo logo, please wait, then windows login. I posted this in the discord, just need as much help as I can get. I forgot to mention, a .dll file (non windows) had a virus called tiggre!rfn, and I just had a power outage.
