First time poster here. I've got a user with repeated 0x50 bluescreens. We've ran through several extended diagnostics on L2 cache, on memory, etc..
We thought initially might be a driver issue with burning software, uninstalled the software and we still have same problems. Followed the instruction on the board from previous messages and made a logfile from the latest minidump. After posting the minidump in the appropriate category and tmcomm.sys was apparently identified as being related to the issue. User's hijack log was requested and asked to to be posted in the proper forum. Followed the instruction in the stickies. Attaching the minidump file here and pasting the Hijackthis log. Any help or suggestions would be greatly appreciated.

Logfile of HijackThis v1.99.1
