Upgraded to Windows 10, all seemed well but couldn't cope with the issues with flash player so decided to roll back to Windows 7. Unfortunately now mouse and keyboard (both USB) are unresponsive when win 7 has loaded, obviously this means I can't do anything as I cant get past login screen. Tried using other USB ports, same problem, tried safe mode, same problem, they are showing up and working in BIOS but nothing else, I have tried system restore, not helped, I have the Windows 7 disc but nothing else. Last thing I want to do is reinstall Windows 7 from scratch as presumably this would cause data loss ?
Any help would be appreciated.
