safari not loading

Hi - all of a sudden my safari doesn't load at all. What might be the likely cause/s and what steps do I need to take to fix it? Help please ....

Could be a whole sort of issues related with this. If on wireless, you could have a bad signal. You could have a bad ISP connection. Try resetting your router/modem. Safari might just be having a mind of its own. Try quitting out of it and restarting. Try restarting the computer. Try turning off the Wifi on your computer, if it has wifi, and turn it back on. There could also be a cashe issue. Reset Safari and empty the cashe.

And, as a measure of last resort, throw the computer out the window and buy a new one, along with a whole new network setup. That should just about guarantee a fix

What model, what operating system and what version of Safari?

All pretty important information.
