Sorry for late reply! was on my lunch break. back to work! Now where were we?
Right, If a clean install is not an option, then maybe try some quick fixes. Have you got any antivirus/antimalware/antispyware software installed? Is windows defender on? Windows Firewall? Have you run a defrag or disk cleanup recently? Try uninstalling programs you dont want/use. download and run CCleaner, Malwarebytes and AVG free if you dont already have them. Uninstall old drivers and make sure you dont have any conflicting drivers. Try all this because sometomes there could just be one file, or one virus that F**ks everything up for you. lol
