sounds like your windows installation is messed up. back up your data and then restore the laptop to factory settings using the system restore partition. check your acer manual or their website on how to launch the system restore process at boot time.
Thanks for the quick reply. I cannot get the windows window up when i switch on. all I get when I switch on is the start up in safe mode, safe mode with networking or normal windows, when I try it starts then goes back to the same screen
