I hate computers!!!

Ok, somebody please help me! Last night my gmail went down. It was still down this morning. I knew it was just me, so I had a friend log into my account. She had no problem. I used hubby's laptop. Again there was no problem. I can't get into it from THIS computer. I NEED to get into the gmail from here since this is my main computer where I do all my work.... and gmail is my work account. So if I ha to send drawings and such, I'm outta luck. Is there a setting I somehow changed?

I deleted all cookies, I did a system restore, I don;t know what else to do!
