Windows 7 Media Center/ Media Player/ Winamp permanet blue screen

Hi,
using above mentioned tools playing music causes Windows 7 after 2-5 to crash with a blue screen (Memory_management).
This behaviour is reproducible and happens whatever palyer is running.
-I tried to run pc in clean boot environment the same is happening
- i tried sfc /Scannow utility (some errors found in language packages but I cant see any problems caused by this

Environment
Windows 7 6.1.7600 Build 7600 Home Premium 32 bit
Asus P5b-Vm no special soundcard installed
Nvidia drivers are on the last update level
Soundmax driver is on the last update level
Automatic update is on

This is a Pc with a dual boot enviroment. XP is running since years on another harddisc. Of course no problems using XP.
Means this problem is coming from and with Windows 7.

Any ideas, how is it possible to analyze dumps to find problem .
May I use a debugging tool and which one?
Thank you
Reiner
