Even if you computer is "outdated", it should still be able to access the internet. If you are getting this error, it likely means one of the following:
 * 1) Some important setting on your computer has changed
 * 2) Your computer has been hacked/got a virus or some other malware
 * 3) There is an issue with the equipment that connects your computer to your internet service provider's (ISP's) infrastructure
 * 4) There is an issue with your ISP's infrastructure

The latter two require you to contact your "provider". - Edit:

Possibility #5 is that some entity (likely some government) is trying to prevent you from accessing certain sites. Depending on where you are and where you are from, this may or may not be likely.
