2 hours is not long enough to test with Memtest. Overnight at least.
That's not the problem though, I believe. It's a driver
, based on this:
"An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers
using improper addresses.
If a kernel debugger is available get the stack backtrace." Bug Check 0xA: IRQL_NOT_LESS_OR_EQUAL
If you post the actual compressed .dmp file, we could probably tell where to start looking. It is due to "memory corruption", so a long Memtest run is recommended too.
