GPU-Z (both 0.6.5 & 0.6.2) does not show any values in any of the tabs on my WinXP 32 SP3 system with a GeForce GTX550Ti video card using the Nvidia 30142 driver. The Event system log shows that the GPU-Z service was successfully sent a start control. GPU-Z works as expected on my Win7 x64 system. Any ideas on what might be happening?
