It can really make a difference if you give us more information. Just saying that something isn’t working is not much we can do with. We are not mind readers nor can we look at your system 
You can’t format Windows. You can format a drive.
So what did you do exactly?
What OS?
What happens if you try another browser?
Anything in a log file?
Are ALL drivers installed (including mobo drivers)?
etc etc
edit: I think you should have posted this in the off-topic forum.
