I am running out of ideas.

Looking back over what has been tried and the continuing random BSOD's I would think there is still a problem with the memory and I suspect that the fault probably lies within the motherboard. With such a major failure result on the high speed RAM slots when testing with Memtest proves that the motherboard does have a fault. That fault could be having an effect on the other slots.

The only other tests I would try is:
Running the hard drive diagnostics from Samsung.
Swapping the PSU with a known working PSU from another PC.
Running another PC with your memory sticks fitted in it.
Running your graphics card and wireless adapter in another PC (with correct drivers loaded)
Backing up all your data and doing a format and re-install of Windows.

Whatever is done it is not going to correct the faults detected on the high speed RAM slots so I would think your motherboard needs to be replaced.

From the list above my priority would be to prove the RAM sticks, graphics card and Wireless card perform without error on another PC and I would be using a voltmeter to check all the voltage rails on the PSU while under load. Swapping out the PSU with a known working PSU from another PC would be the easiest way to prove that the PSU is, or is not, adding to the problem. (The glitch you found on the PSU power switch, earlier, does raise suspicion as to the condition of the PSU).

All we know for sure, prior to running these other tests on your hardware, is that a fault does exist in the motherboard. Personally I would be looking for a replacement motherboard, but I would not want to say "go and buy a new one" without having proved all the other hardware is 100%.

I will begin doing these tests after the next BSOD, thanks for the help will keep you updating

Alright had 2 more BSODs today and a freeze. If you want I can upload the BSV/minidumps but I don't think it matters at this point. I am going to run the hard drive diagnostic and uninstall microsoft security essentials (an MSE error still shows up around the time of my BSODs :| )

Hard drive diagnostic came back clean, and I am now running Avira instead of MSE. Going to run this until another BSOD/freeze shows up, then its on to testing the hardware or RMA'ing the mobo

OK, I think changing the mobo is most probably going to be the solution, but lets see how it goes.

I'm also going to run a MemTest overnight (10 hours-ish) to 100% verify the RAM works. Only problem is that if I do get errors, I'm not sure how I will distinguish between RAM error or DIMM slot error

Testing your RAM by installing it in another PC would be far more conclusive.

The trouble with Memtest is that it does not run the RAM the same way that Windows does. It therefore is only likely to spot some defects while missing others. I have often seen it pass a RAM module with flying colours only to find the same module causing an error when in use by Windows. This is why I always recommend running the PC for a length of time on each individual RAM stick.

In your particular case the best test for your RAM is to run it in another PC so that the suspected motherboard fault cannot interfere with the test. If the other PC then starts to crash you will no for sure that you have a bad stick. The other method would be to borrow RAM from another computer (that is running fault free) and see how well it runs in yours as that will prove if it is your motherboard.

Unfortunately I do not have another PC that uses DDR3 RAM. However, I have another set of the same exact RAM that I am using now.I will put this in my system and wait for a BSOD (just had one this morning with MSE uninstalled, guess that didn't work). Only problem using this method is that if somehow both sets of the RAM are faulty, or there is a problem with the RAM model and the motherboard (even though it is on the mobo's QVL).

As the RAM is on the mobo's QVL it is extremely unlikely that the RAM has any compatability issues with the mobo. It would also think it unlikely that your other set of RAM is also going to have the same errors.

You could swap around the sticks and see if any of them show more faults than the others. Doing this with just one stick at a time would be easier to evaluate.

At the end of the day the bad result on the high speed RAM slots would be enough to convince me that the motherboard needs to be changed. But, the decision has to be yours.

Running with the different set of RAM installed until the next BSOD. If I get another one, I'm replacing the motherboard. Would you recommend RMA'ing it, or just buying a new one

If the board is still under any kind of warranty then getting a replacement would save some money. Motherboard faults are not common.

Reading this thread was like reliving the past few months. I've been having similar issues in February when I got the same motherboard that you have. The computer (all new parts) was fine for a month before I started having all sorts of bsod errors. I isolated the motherboard by doing testing with different components. Then I RMA'd the motherboard and got the same one back from ASUS not knowing if they did anything to it or not. All was well for a couple of months before the crashes began again. It seems they start at about once per week and become more frequent. I was doing a search when I found this thread and am about to RMA the motherboard again. Wish you luck!

BSOD brothers! If I summon the resolve I might just buy a new board. Not sure if I want to deal with this again :| Good luck to you too

@ Mooster: It almost sounds like Xbox 360 red rings. It works fine for a couple of months until some unknown part breaks when it gets stressed from heat for a long time. You send it in, get a replacement, and it works for a while until that part breaks again. Just my analyzation.

@ Mark56: Got a freeze a few minutes ago. I guess its time to start looking at motherboard options. If I were to buy a new one, any recommendations on AMD, AM3, DDR3, PCI x16 motherboards for under 130 bucks?

Steve S, if you want recommendations for new parts I would suggest starting a new thread in the "Processors & Motherboards" forum.

There are helpers here with good knowledge on new mobo's, CPU's, etc, I'm sorry to say I am not one of them.

I hope it all comes good for you.

I found a good motherboard on NewEgg this morning. Will be buying it tonight. Thanks for the help everyone

Your welcome.

Please do let us know if it cures the problem.

4 BSODS/Freezes tonight alone. UPS needs to hurry up
