can you see your windows event viewer and see what log save there ?
last crash (and all the previous). source: Application error, event code: 1000, category: (100), and full path to SRBMiner exe file. Nothing else near.
I'm catching error 1000 event via scheduler and run reboot.bat in case of it. Rig reboots and goes well for next 6 or more hours
If so, im probably not releasing some of the CL resources as i should..
