Hi,

I have no idea if I should post this in network connect section or this section. Sorry if I posted in the wrong section.

I got a blue screen error while trying to connect to WiFi, but now the system asks me for my username and password. But i don't have any and I don't know what users name and password, the WiFi user name or password? or the windows account and password?

Can anyone help me?

Your system seems corrupted. You might be looking at a complete reinstallation. If you do this , I would start with a new download of the ISO file from a known good site. Burn the ISO file to DVD using a slow burn, then start over.
