It wont let me go on internet in safe mode.
You need Safe Mode with Networking. The picture is taken off the interwebs, and is perhaps misleading with "Safe Mode" being the option highlighted, so I should have made that bit bold in my original reply.
Also you may need to use a wired connection (Ethernet cable) to the router/modem to get on the internet.
The only reason to do this is to rule out an infection. As just copying the files to an external drive from safe mode has the risk of spreading any nasties to another machine.
