it caused an expection / bluescreen on my HP ProBook 650b during startup , I deinstalled the sounddrivers, now the system crashed somewhere else ... I can not blame STacSV.exe for being the problem.

it's using all my cpu. im not a techy i just want to smash my laptop when this happens

Here the error message appears immediately after network login, so before loading the Windows icons and taskbar. EJ Smith, I don´t use Dell

If it's not a virus masquerading as the original, it can be the driver for several audio cards. If it is taking 50% of your CPU, AND you are not playing games or listening to music AND you have the DEFAULT driver for all the MS Window sounds, you probably have a virus. Before panicking, be sure you are not using your audio - just muting it is not the same as not using it.

when i get the "STacSV Module has stopped working" message, my speakers no longer mute when i plug in headphones. i get sound in my headphones and over the speakers

Yes it is for sound card. Update your drivers if it is giving you issues.

It is resource hungry, keeps processor hot so fan runs contantly on full power.

eehm,security task manager said this process is giving 99% CPU. now it's always 100 CPU.... what to do?
