Hi, everyone! I have a problem with a Sony Vaio Laptop, it is incredibly slow, it takes about 10 minutes to just start up... and it even takes more to load the applications. I don't know what could be causing it. The only thing is that it has Norton Internet Protection antivirus, now, I know that this antivirus slows computers, but it doesn't slow them that much. So, what do you think this could be?
