Windows vista x64 constantly crashes

I've installed windows vista ultimate x64 in a brand new Gateway GT4220m that originally came with Windos Vista Home Premium.

After the drama to find the required drivers for it, all seemed to work fine. All updates for the system and the drivers where downloaded.

Anyhow, suddenly the system started to show a warning telling that there was a problem with the STacSV.exe

Now it does not appear very often, but the system freezes and it is needed to reinitiate it turning off the machine.

I've noticed that it hapens when I use itunes, WM or play pictures in a presentation mode. If the machine goes to hibernation mode, it won´t wake up, so it is needed to turn it off again.

I am unable to use the windows media center as well.

Would it be OK to reinstall all the drivers? Do I have to run the Windows Vista installation in repair mode or reinstall it clean again ?

Well you could try to reinstall some of the drivers to see what happens, maybe it's something wrong with the video or sound driver if you say the machine is crashing when you use multimedia applications.

try this link and see it it helps.

List your system spec.
Download the latest codecs may help.

Try looking in your error logs by;

Left Click on Start Menu.
Right click on Computer and choose manage.
Click on the event viewer.
You now have loads of options to try and pin down what is happening.
Expand the error tab.
Look for things in the last 24 hours.

I would refrain from stacking the PC with Codec mega packs especially those dodgy free ones.

Ok... thanks to you all !

I've went to the stacv process information site, but the program does not run in x64 version

I've looked or the latest codecs and I already have those.

Then, I've went into the error tab and found the following error that are shows quite often:

Of course I have no clue about what those are related with .

Oh, I must say that I ran the Windows Media Center and it seems to work fine, but of course,the crash problem still occurs.

Thanks again!

Try looking at your services to see if any service that is required for sound has been stopped by;

Left Click on Start Menu.
Right click on Computer and choose manage.
Click on the Services and Applications Tab
Double click on services.


If a service has not started then you can start it by clicking on the Start tab at the top left. Alternatively you can double click on the service to make permanent changes.

Thanks,

I have checked the services and all seems to be working fine.The only one that is unhabilitated is Windows Media Center Extender Service.

After reinstalling all the drivers the STacSV.exe message appeared again

doing a search for your motherboard on google is telling me your computer is made by gateway and not dell. Have you got the exact model of your motherboard?

ups! Sorry, it was a super typo! Yes, my PC is a Gateway.

The motherboard is an Intel (R) G33 /G31 Chipset family
