As a conclusion:

I upgraded Realtek driver for onboard audio from Gigabyte support page (http://www.gigabyte.com.tw/Support/Motherboard/Driver_Model.aspx?ProductID=3005&ost=xp#anchor_os) and then re-enabled onboard audio.

The PC runs OK and sound is OK too.

So, for GA-MA790FXT UD5P owners encountering BSOD at login (XP SP3), I recommend the upgrade of Realtek driver, in the case onboard sound is enabled.

Thanks for the valuable information I found here.

Thanks for this guide.

I encountered a BSOD issue on a AMD/Gigabyte newly assembled PC running XP SP3.

Not every time, but often, BSOD occurred when attempting logging in when asked to. After a RAM verification by MemTest86, and a cleaning with HighjackThis and SmitfraudFix, issue appeared fixed but some days later, BSOD was there again.

As a file was often indicated (portcls.sys), I disabled onboard sound and now, the issue seems to be fixed.

Nevertheless, I'll try to upgrade mobo sound drivers and try then to enable onboard sound again, knowing that there is a backup solution.

Mobo: GA-MA790FXT-UD5P

Proc.: Phenom II 955 x4, no oc
