Here's the DxDiag. Machine name has been removed for privacy reasons. I hope that doesn't interfere.
TiWorker.exe is a system program. esent.dll usually associated with an exchange server but is found in many Windows versions. ntdll.dll points to a bad disc or some form of data corruption (memory module maybe).
The games HomeFront.exe, PlanetSide2x64.exe, and Gunpoint.exe are also generating a windows error report (wer). The wizard's first impulse without seeing the computer was memory module. Another thought - bumped something while poking around inside the computer. If that computer was on my work bench I would give the insides a real good visual inspection (no connectors loose, bulging capacitors, etc) followed by making sure everything was connected securely. Then I would pull the hard drive and gen up a clean windows install. If the computer is still running good I would install the game.
additional thoughts power supply just starting to fail - bulging filter capacitors, voltage regulators failing
motherboard again capacitors - bulging tops and no brown ooze
hard drive - excessive clicking means bad sectors
memory modules - if you switch them and get different problems you got a bad one
reset the bios and let the motherboard set default settings
