The best way is get a new hard drive which is very cheap nowadays (160 GB is about 10 bucks), then follows these steps:
1. If you're having phpMyAdmin, use Export to backup your MySQL databases; if you don't have phpMyAdmin, use function MySQLdump w/ MySQL consol to backup db. Also, backup all web sites.
2. Save those backup files/sites in an external drive or usb stick
3. Swap out that current hard drive w/ the new one
4. On new hard drive, install only 3 things: windows, Antivirus+Firewall, and wamp
5. Restore db w/ Import from phpMyAdmin or MySQL consol and save backup websites in c:/wamp/www folder
6. If you store your_file.php in c:/wamp/www folder then access as follows:
[
localhost]
If you store your_file.php in c:/wamp/www/your_folder folder then access as follows:
[
localhost]
Your sites should work as expected; if not, you still have all your files in your old hard drive intact. After everything work as expected, install back all software 1 by 1, and make sure to check wamp after each installation to find out if conflict.
