1 BSOD minidump - blaming ntkrnlmp.exe (the NT Kernel) as a cause. This is unlikely to be the true cause.

Possible causes -

ASACPI.sys   Mon Mar 28 15:30:36 2005 (42476C4C)
SCDEmu.SYS   Fri Jun 13 09:38:37 2008 (4851975D)
ASACPI.sys - ASUS ACPI Driver; near guaranteed to cause BSODs on Windows 7 systems. Update link here, update instructions (slideshow) here (note that in the last step you select the ATK0110 driver in the list instead of the one mentioned)

SCDEmu.SYS - PowerISO driver. Uninstall PowerISO for now.

If problems continue after dealing with those 2 drivers, run Driver Verifier - Driver Verifier - Enable and Disable

Thank you for your input reventon. I have updated the ACPI driver and installed PowerISO but am still experiencing the BSOD. I am enabled driver verifier and rebooted.. I don't see if running anywhere.. I assume I will be notified if one of my drivers is determined to be unstable?

Should I be investigating the possibilities of bad memory, overheating, insufficient wattage from PSU, ect.... or is it pretty clear that this is a driver issue?

Thank you again for your assistance.

If Driver Verifier does not pick anything up - then it's a Hardware problem.

So, while I wouldn't go swapping parts out yet (at least until you see if DV causes any BSODs) you can run some hardware tests to try to find a hardware fault. (run the Blend test as well as the Small FFT test)

RAM - Test with Memtest86+

Video Card - Stress Test with Furmark
