Hi i got to report a bug which caused a extrem crash for me. I watched a Video on Youtube, and started GPU-Z. When GPU-Z was loading it seemed like it locked up. So i tried ctrl+alt+del but nothing happend. Music kept playing. Then my screen became black, music stopped and the GPU fan ran at 100%, then my screen went into idle mode and didn't wake up anymore. I had to push the reset button. Uefi reported that it tried to reboot multiple times which kinda scared me because i never had such a message from UEFI before. I never had such an issue before. Now when i start GPU-Z it seems to work, but while loading it seems to slow down the system for example music will be "slow" for the moment when GPU-Z loads although i have a good system. When i started GPU-Z for the first time after this crash it told me that the crash happend when loading Open CL. Here are my specs: Asrock z68 Pro3 Core i5 2500k Sapphire AMD 7850 2GB 4GB DDR3 Win 7 x64 Also: GPUZ seem to have a bug when reading my clockrates(happens with any driver). The clockrates it reads are incorrect. It reads the clockrates of the OC version of my card although my card isn't a OC Version and runs at stock settings.
