My computer can't start normally?

I was showering and then when I came to my computer, it showed that I had a msg from my friend saying “hey is this a pic of you?”
and then there was a link. I copied it and tried to open the link but it didn’t work. Then suddenly my computer shut down and now I can’t start it. I now know it was a virus. I need my computer to communicate to the girls cause we are going to a party tonight and I don’t know where it is. WHAT CAN I DO?

ALSO I NEED MY COMPUTER FOR SCHOOL.
