Okay, first of all.. i didnt read all thats posted so im sorry if i say something that already been said.
Small checklist to keep;):
Full system restore
Full Virus and Spy/Adware scan
Registry Cleanup (contaminated registry can cause big problems)
Login with Administrator and delete and Recreate all user accounts (dont use account manager, better to use the "manage system" screen, add all users to the Administrators Group
Reinstall of Firewall software, make sure you delete all previous settings to be sure all ports are re-opened.
Thats about the most basic i can get... However my only advise would be: Do a fresh install, if you dont like to take the time for it, maybe its an option to install windows and all programs you often use. Then Create a Full System Ghost
