Problems with Standby (S3)

Hello,
i just bought the card and i am using it in a HTPC. I use "Lights Out" to save Energy. The HTPC goes to standby after 5 Minutes. After the wakeup the card is missing. I have to shut down the PC. Normal reset does not fix it.
HTPC Specs:
http://www.shuttle.eu/_archive/old/en/w ... ex-19.html
CPU: AMD 64x2 3800+ EE
RAM: 2 Gbyte
Graphics: ATI 4350
If i cant get the card working with S3 i have to return it to the dealer...
Hope, you can help me.
Regards
Volker
