I recently had a PC built for me by a friend, about a week ago my computer kept crashing. I didn't know it at the time, but the reason was a fan fell out of place and the processor was over heating. Before I realized this, I kept trying to start the computer up and get it into safe mode, but of course it kept crashing. I ended up open up the case and putting the fan back in place and everything was fine again. Except I couldn't connect to the internet. My novice assumption is that I must have did something when I kept trying to restart the computer and find out why it was crashing. I did a system restore to a date a week earlier and I was able to go get back on the internet. My problem now is that my internet is noticeably slower than it was before all of this happened.
