Every time I switch my computer on boinc manager says error, it is not connecting to "localhost" nor is ithe manager showing localhost when select computer is selected in advanced view. Only way to resolve this is to reload BOINC to my HDD, very off putting! Any suggestions??

If you mean that you get the message "BOINC Manager cannot connect to a client", then first check if boinc.exe is actually running. Do so in Windows Task Manager. If you don't see it running under your own name, do "Show processes from all users" first.

When boinc.exe is running, it may just have its 'chat-channel' blocked by your firewall software. Since you complete newly installed BOINC, you may want to allow boinc.exe and boincmgr.exe through your firewall again. If it needs a port number, TCP 31416. Boinc.exe needs access to the internet on TCP ports 80 and 443.
