Visual 'Lock Up'/Crash after few minuts

2.5.2.11 (current)/ 2.5.1 (previous)/ and the current devstest build as of just befor this post.

Attachments: Not that the information is there (all my tech support, ive never doven too deep into a dx diag file). 01 is just after closing the game, 02 is during a lock up.

Game locks up anywhere from a few seconds to several minuts in (even sitting in the menu). doesnt crash, but all rendering freezs on its current frame on both my monitors, after a few seconds every toher programe but FTD will resume. only experiencing this issue with FTD (dont even notice similar stuttering on anything else). all other programes will resume exept for FTD, i can hear agmeplay (placing blocks, ect) but it will be stuck on one frame.

ive treid rolling back a version, and forward to devtest. i thought ti was maybe an issue wiht youtube or other games. so far im at a loss to find out the source of this. whyll it only started after the last update rolling back didnt fix it. currently, i cannot play the game due to the rate at which it locks up.
