I had to uninstall firefox as it had changed to the ask.com search engine and was not working properyl for sum reason so when i uninstalled it i have not been able to connect to the internet since. Internet explorer is non responsive so i tried installing my internet provider disk which says im connected and loads up the icons but i when i click on them to connect still nothing happens. Also my sytem restore points do not work either but the laptop im suing connects no problem so must be something stupid on the pc that needs sorted out. Will it need formatted and a clean start again?
