BSOD on PXIe-8840 running Windows 7 64

[FM82]

Good morning,

We had implemented an ATE, to run long time test, with the PXI in object. During the preliminary test we encountered problems due to the BSOD of W7 after some hours (within 12 and 36) of continuosly running.

I have check the memory dump of the errors, via WinDBG, and seems to me that problem is CPU related (maybe heat?) due to corruption of the cache memory. The application running on it was completely developed with Labview.

I attach the revelant result of the dump analisys:

BugCheck 124, {0, fffffa800530b028, be000000, 100110b}

*** ERROR: Module load completed but symbols could not be loaded for igdkmd64.sys
