Continous Bluescree with Win7 SP1

Hello,
my old system worked for many month now without any problems.
Q-BOX S2 Windows 7 Ultimate 64Bit
On my new system, I have tried the latest drivers and at end installed the same old driver I have on my old system, I get continous Bluescreen at the time the Q-Box is activated.
Plug-in USB or starting the TV-Program.
Not always, but very often.
On my new system I have installed Windows 7 Ultimate 64bit SP1.
Does Q-Box S2 have problems with SP1 of Windows 7 ? It is the only thing that is different to my old system.
best regards
Andreas
