I have new computer, I had on in two systems, Windows 10 and Ubuntu. Last time I downloaded some elements to SQL management studio from untrusted side and my computer becomes so much slower, and I must wait for system option about 5-10 minutes. I haven't seen anything in task manager. So, I prepared my computer for new installation both systems, I deleted all partitions, created new and install Windows again, everything went good but my computer is still slow. When I want to install Ubuntu I have many lines of this :
blk_update_request: I/O error, dev sr1, sector 262136
My question is, what should I do ? I have no idea.
