Why when installed my old sound card. windows xp broke?
it sound like you sound card is the reason windows gave you the blue screen of death I suggest you replace it if it’s built into the mother board just fit a new PCI sound card but first disable the original sound card in the device manager then fit the new card and install the drivers for that then everything should be OK By the way you will still be able to get into windows if you start in safe mode then disable the original sound card while in safe mode via the device manager you should also uninstall the drivers as well
