That is not a software problem.
The headphones/external speakers jack socket has a switch to exclude from audio the internal speakers, when a jack plug is connected.
This is a very simple device and is not software controlled.
The fact that it has gone faulty at the same time you reinstalled the system is a coincidence.
If it does not mute when you insert headphones, all you can do is trying to play with the jack plug , inserting and pulling it out. If this does not unlock the switch, the alternative is having the jack socket replaced by a technician. This is generally an expensive repair, asthe socked is soldered on motherboard.
A cheap alternative to a proper repair is using an external USB to Audio Adapter and mute the internal audicard when using headphones.

Comapq Presario 770 Tu - Driver for WinXP -Audio & Wireless


Here's a link to Compaq's XP driver page for the 770tu. There's not much there. What you may have to do is find out the make and model of the sound card (wireless card for the other person with the wireless issue) and go to the manufacturer's site or driverguide.com search at driver guide by the scrd's make and model. You may be able to find some drivers at driver guide by the machine model as well. I've put XP in a couple of Toshibas that I had to open up to find the sound card type, you may also be able to find the type in the device manager or at Compaq's support site under the system configuration.
