Actually, you shouldn't blame the computer, if you can do anything on your computer offline fine, then its the connection you need to blame, maybe you have a downtime connecting to GMAIL. And making comments like that make me wanna just kill you, can't beleive how. Do you feel good after making that kind of comments, you feel more cool? just wanna know, you look like a perfect idiot to me.
same but sometimes isp can have connections on certain hosts, cant connect to it so just wait a while like 2-3 days it should be fixed, if not try contacting your isp and ask them what to do, try changing browser before doing that =)
