2 or 3 days ago windows mail stopped downloading emails. Firefox, Mail, and various other problems sometimes work or come up with not respoding. If I close it after not responding it wont then open again untill rebooted. I have tried to do a virus check with BT net protect plus but it stops after 60 files. I have tried to download avast and avg antivirus but they wont download. I have tried using system restore for 30th September and 7th September but that does not fix the problem. I have tried to go into safe mode pressing F8 but instead of the usual list of options it just asks what I want to boot from DVD or Hard Drive. I press Hard Drive and PC starts as normal. I have put in the set up disk and it freezes ath the point where it asks to check for updates in the intial checks. I have used the scan now feature in command prompt and it found that there were no errors. I have checked internet connection and am connected and can browse if firefox starts up and still getting my normal speed. Any help would be great thanks
