Windows 7 Random BSoD - IRQL_NOT_LESS_OR_EQUAL

[TheRealOne]

Hi all,

Long time reader, first time poster.

I've been recently having troubles with a new PC build of mine (constructed at Xmas '1Link RemovedLink Removed0), whereby I am getting completely random BSoDs. These happen at varying intervals, anywhere from immediately after startup to 5-6 days after the previous one.

As it's only very quick (memory dump), I've managed to catch that the main error seems to be IRQL_NOT_LESS_OR_EQUAL.

Having little knowledge on interpreting such messages, I've tried all the usual bluescreen repairs (memory tests, chkdsk, various hardware drivers), all to no avail.

I've attached the most recent two bluescreen minidumps, hopefully they can be of assistance in rectifying this problem.

Thanks in advance

UPDATE: Have suffered a new bluescreen error, this one displayed as BAD_POOL_HEADER.

Thanks again.

Minidump is the following:

BAD_POOL_HEADER (19)
The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.
The internal pool links must be walked to figure out a possible cause of
the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Arguments:
Arg1: 0000000000000003, the pool freelist is corrupt.
Arg2: fffffa80069dbb20, the pool entry being checked.
Arg3: fffffa80069dbb20, the read back flink freelist value (should be the same as 2).
Arg4: fffffa80069db320, the read back blink freelist value (should be the same as 2).

IRQL_NOT_LESS_OR_EQUAL (a)
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.
Arguments:
Arg1: 0000000100f660f0, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :
 bit 0 : value 0 = read operation, 1 = write operation
 bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002c7d3e3, address which referenced memory

Also have u tried memtest86 ? , this will check your ram if ther are any errors

 

[TheRealOne]

Cheers kaos, just ran memtest86 through my system, turns out it was an issue with my memory, some new RAM and a clean install of windows has fixed it right up

 

[kaos]

glad that helped
