A month ago I downloaded Daemon Tools and it asked me to download an update, so I did. It wasn't from the official website though. I think it was from this: Disc-Tools.com it asked to me to restart my computer and now whenever I shut down my computer and try to turn it on, Windows can't start itself and I have to do start up repair a few times for it to load. I don't turn off my computer anymore because of it. Can I fix this or should I just get a new computer?
