So this afternoon I was on internet and suddenly the screen went black and the computer started back on it's own. I opened Firefox again but it said Firefox doesn't respond. I threw Firefox away and went to look for Firefox again on IE and downloaded it again to see if that would solve the problem, but it doesn't. Then I tried to restore the system back to yesterday, but still Firefox doesn't work. I'm on IE right now and I really hate it lol. So could anyone help me please?
