I installed Windows 10 wanting to test out the new system, but after a driver compatibility issue which I grew tired of trying to understand and resolve, I opted to revert to my original Windows 7 Pro OS. Unfortunately when I tried to open webpages after the rollback, neither Firefox nor IE would work, even though LAN and wifi are working fine. I've tried all sorts of options to get it working but it seems this may be yet another issue of driver or software compatibility. Another problem I have is that I don't seem to have been provided with a recovery disc in order to refresh the Windows 7 OS. Ideally I'm hoping someone may be able to suggest something to help, because nothing has worked so far and the forums I've tried online aren't especially helpful. It's a 64 bit system, and it's an Acer Travelmate P643-V, if that helps at all. I tried installing Chrome and even wanted to reinstall Windows 10 but without working internet I don't know how or whether that's possible. Any further info required just let me know and I'll do my best to cooperate.
