Just to check, did you reinstall your wireless card drivers?

Start> Control Panel> Administrative Tools> Computer Management> Device Manager

or

Start> Control Panel> Performance & Maintenance> Administrative Tools > Computer Management> Device Manager

See if there are any yellow exclamation marks. If there are, it means those devices are having problems. Your wireless card should be under Network Adapters and see if it has an exclamation mark.
