All, I am looking for some help solving a problem with PinballX locking up in my cabinet. I have 16 tables loaded all are Visual Pinball. All others are set to Enabled=NO. I can load any game and play it with no problems from the editor directly. I can even let the system sit in a game for an hour with no problems. This is a new build, I have not seen the PC show any issues except in PinballX. I have tried turning off attract mode, (it is on now) as this is where I first noticed the issue, ( it would lock up cycling between games) but even with it off if I leave the system sitting on a selection (any selection) it will lock up solid after a few minutes requiring a hard boot. I am starting the application as administrator and have tested in compatibility XP Service Pack 3, and NT 4.0 Service Pack 5, I even tried Windows 7,but no change in the problem. A 1920X1080 Monitor is connected by HDMI to the HD Graphcs 4600, and a 3840X2160 42" 4K HDTV is connected to the GTX 760 via HDMI. As a note the operating system sees the GTX 760 as Monitor 2, and the HD Graphics as Monitor 1. My log file is below: I have made all the Windows updates, and Nvidia driver updates to the system. I have printed and read PinballX_S2F_Documentation rev 1.3, and have spent hours scanning and reading the forums, but so far I am finding nothing that will help solve this. I did install Shark Codecs as recommended hoping it would help, but system still locks up every time after 5 or 10 minutes. I have even been in a game playing and on exit found Pinball X unresponsive. Any help would be appreciated. My ini file:
