BSOD and randomly crashing

G'day all.

First time poster and new member I joined because during my research into my problem I found some good advice here, so hopefully the trend will continue.

Well, I'm own a local computer repair company but am having trouble narrowing down a problem, ironically on my personal machine... how embarrassing is that?! LOL!

Symptoms:
-Occasionally I get random graphical anomalies such as colored boxes or a grouping of colored pixels out of place.
-If I do see these anomalies I know I don't have long until a full crash. However, sometimes if clears itself up, but inevitably does end up crashing sooner or later.
-Lately it has been simply freezing and I have to go poke the reset button.
-It happens most while playing WoW, but is NOT limited to playing games. I get the anomalies mostly while not playing. My guess is it's b/c I'm stressing the system.

Troubleshooting:
I've swapped the RAM in and out of different slots and run each stick individually in each slot. I've run Prime95 for ~8 hours, Memtest86+ also for ~8 hours, PCMark 06 a number of times. I've monitored temps - all within normal range. I would try different RAM, but I don't have any other DDR3 on hand. If I need to buy some I will (I want more anyway ). I also don't have another GPU. All my drivers are up to date and windows updates also up to date.

Here is a recent dump file: (I'm sorry for the terribly long post...)

KMODE_EXCEPTION_NOT_HANDLED (1e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Arguments:
Arg1: ffffffffc0000005, The exception code that was not handled
Arg2: fffff88000fec304, The address that the exception occurred at
Arg3: 0000000000000001, Parameter 0 of the exception
Arg4: 0000000000000000, Parameter 1 of the exception

Any help would be greatly appreciated. Thanks in advance!

Thanks for the reply.

In further diagnosing the problem I discovered that asio.sys was casing a conflict. asio.sys is related to the ASUS mobo utilites, so I've uninstalled them and removed the driver. So far things are looking good, but it's an intermittent problem.

I'll keep y'all posted
