Random but frequent BSOD. 4e, 1a and 50.

Additional information is required - not just the .dmp files.

1. Download the DM Log Collector application to your desktop by clicking the link below

DM Log Collector.exe

Could not read faulting driver name
Probably caused by : memory_corruption ( nt!MiAgeWorkingSet+425 )

You need to rule out memory problems - run MemTest86+ (note the +) for a minimum of 8 consecutive passes:
RAM - Test with Memtest86+

Please do the following:

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
Driver Verifier - Enable and Disable

Driver Verifier will cause your computer to run very sluggishly - this is normal. What it is trying to do is force your system to BSOD and isolate the offending driver/s. When it does, reboot, disable driver verifier, reboot as normal and upload the new dmp file/s here.

I recommend creating a system restore point before turning on driver verifier:
System Restore Point - Create

If your system fails to boot to desktop once driver verifier is enabled, turn it off by booting into Safe Mode:
