Try loading the website on your phone or on another computer. If the website loads on the other device, the problem lies with your computer. If the website doesn't load on another device, the problem is either with the network or the website itself.  If you can, try to load the website on another device connected to your network, and a device that's not connected to your network. The easiest way to do this is to load the website on your phone while connected to the same network as your computer, and then disconnect from the wireless network and load the page using your cellular data. This can help you determine if the problem is with your network or with the website. If the website won't load on any device regardless of what network it is connected to, the website itself is most likely down. You can double-check by looking up the site on a monitoring service like "Is It Down Right Now?" (iidrn.com). Oftentimes, a simple reboot will fix the problem you're having. Reboot your computer and test the website again. There may be some settings configured incorrectly on your browser. Try a different web browser to see if you can load the website. If you are using the default browser and don't have any others installed, you can quickly download and install another free browser like Firefox, Chrome, or Opera. Your antivirus software may be interfering with your ability to load certain websites. Try disabling the software and then loading the site again.  Right-click on the antivirus icon in your System Tray and select "Disable" or "Turn Off." You may be warned that this isn't safe. Make sure to re-enable the antivirus after you're done testing. Traffic to or from a certain website may be getting tripped up by your modem or router. Resetting these devices may allow you to access the website again.  Unplug the power cables for the modem and the router (if you have a separate one), and wait about a minute. Plug your modem back in and wait for it to completely light up. Plug your router back in and wait for it to completely light up. Try visiting the website again. If your date or time is set incorrectly, you may not be able to connect to secure (https://) websites. Check your computer or mobile device's clock to make sure that it is set to the correct time and date. If you have parental control software enabled, it may be blocking access to certain websites. If you have access to it, disable the parental control software and try accessing the website again. The process for this varies depending on the parental control program being used.
