Dump file: 090610-19578-01.dmp This was likely caused by the following module: ntkrnlpa.exe Bugcheck code: 0x50 (0xF3400107, 0x0, 0x82A72C51, 0x2) Error: PAGE_FAULT_IN_NONPAGED_AREA Bug check 0x50 usually occurs after the installation of faulty hardware or in the event of failure of installed hardware. Another common cause is the installation of a faulty system service. Antivirus software can also trigger this error, as can a corrupted NTFS volume. 1. Chkdsk /f /r 2. Disable the AV and see if this resolves the error 3. I still see: nvsmu.sys 29.06.2009 (NVIDIA nForce(TM) SMU Microcontroller Driver) nvhda32v.sys 27.06.2009 (NVIDIA HDMI Audio Driver) Did you follow TorrentG's recommendation to update them? After uninstalling the current NVIDIA driver set, did you apply the Driver Sweeper?
