Sound Card Drivers

My bro has this compaq and he installed a new soundcard in it because his onboard didnt work straight...so he uninstalled the drivers of the onboard and installed the soundcard...now he gets a blue screen....now it just randomly restarts....so i told him to disable the new soundcard and its been working fine...does this mean his power supply isnt powerful enough....but the requirements of the soundcard is fine...so would i have to get new psu for him also he wants to know how to install his old soundcard...pretty sure it was realtek audio 97 drivers but like i dont know what to tell him...

Did you disable the onboard sound before installing the new soundcard?

yeah, im pretty sure...if i didnt then it would still be in device manager wouldnt it?...how do i undisable the old one? because it doesnt show up in the list

Tried disabling in the Bios ? Hit del ? on start up and look for it there .
