Application ErrorFollow

Any tech-types folks out there that can help me with this error code I keep getting. When I fire up FFXI and run around unpopulated areas I'm fine. However when I go do campaign or go to the AH after about 1-2 minutes my screen freezes, the music plays the same 3 second clip over and over and I have to hit CTRL/ALT/DEL to kill full screen mode. When the game closes windows works fine. Here is the error message I get from the error logs:

Application Error

Faulting application pol.exe, version 1.18.7.0, faulting module
ffximain.dll, version 3.0.0.0, fault address 0x0005564b

I've run chkdsk, defragged, tried new driver for my video card, new Direct X drivers and no joy. =(

I've run out of ideas.

- Did a POL check and nothing...
- Reinstalled FFXI and same issue
- dropped mem timings from 1T to 2T
- tried lower resolutions of the game
- took PC apart and cleaned everything possible and checked all connections

The screen didn't freeze up almost immediately as before. I could actually check the AH in Whitegate. But when I went to campaign to check out if I could battle it took about 5 minutes before the screen froze and the music was skipping in the back ground.

sadly you could be right about the mobo. I pulled the video card and ran the game on the on board graphics and the same issue occured. I am thinking the CPU might be heat damaged as the game only freezes when under heavy CPU load. Weird as its gone from a rare problem to weekely to daily to by the minute oevr the last few months. =(

Thanks to all for the various suggestions
