Comp freezes after 3 mins playing

[Pizzaiolo]

Here is the deal:

-After the games load i have bout 2~3 mins till games and everything freezes.
-Sometimes i get a pre-freeze, stops for bout 10 seconds then i got the real freeze, at this moment i alt+f4.
-Funny fact: if music is playing, the music keeps playing but the mouse, keyboard and everything besides music, freezes.


This thing only happens with DDO. Sadly

dxdiag:

You should attach the entire DXdiag in a code block.

I would make the page file min and max sizes the same; I would choose 3072 MB--double that if you edit large images. (unlikely related to your issue)

What other 3D games do you run?

Are all vents, heat-sinks, fans clean?

What make/model power supply do you have?

Assuming you followed Turbine's troubleshooting steps, I would try, in order:

If you are overclocked, run at stock speeds for a while. (Note: if properly overclocked, its almost never an issue but if you're running near threshold and on aging components...)
Close all unnecessary processes, bloatware; use MSCONFIG to temporarily disable extraneous startup processes; reboot. Excessive Anti-Spyware programs fall under this category. (meaning, choose ONE reliable HIDS program to run real-time; I like Comodo, AVG, or Avast!)
Run memtest86+ for at least one full pass (unlikely the issue but to be sure...)
Run chkdsk /f for each drive.
Run a CPU stability test for 5+ mins, see if it passes.
Run a GPU test as well.
Uninstall DDO; restart PC; clean temp dirs; re-download/re-install DDO. (I like the program, Advanced Uninstaller Free)
If still no luck, underclock; your CPU or GPU may be aged. (rare, but it happens; unlikely if they passed long stability tests)
Find a shaman to remove the bad juju OR do a backup of anything you don't want to lose, re-format/re-install Windows, everything else.
