BSOD While Gaming 0xA0000001 Atikmdag.sys

Here are a few more resources, bit the Max load on the +12V is 600W, which should be plenty,

Hum you mentioned you ran a memory test a while back and I am just wondering if this might e an idea to run

MEMTEST

https://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html thisone you will need to make a bootable disk set the BIOS to optical (or USB ifpreferred) boot the machine and let it run for at LEAST 8 passesunless the errors come up straight away. Takes fair time to complete andsome leave it running overnight.

Ifyou do get errors then you will need to redo the memtest with eachseparate stick to find the culprit. Having said the it could be a slot problem

Chives, if you would please go to C:/Windows/Minidump and send us the last bsod dumps wou have had since posting the first one. If you look at the numbers, they are the dates and time of the BSOD. You will have to give admin permissions. Copy them to your desktop, zip them up and upload the Zip file with your next post, or whenever you get home. Also, I would like you to do something else that could cause the problem or rule out a component.

Next I would like you to run memtest86+. It is quite a long test as it needs to be run for 8 complete passes all at the same time. Please download the test from Memtest86+ - Advanced Memory Diagnostic Tool. Although the names are similar, this test is much better than memtest86. It needs to be run for 8 complete passes or until you get an error. If you get an error, stop the test. In the link above if you will go down to the middle of the page you can download either the ISO file which needs to be burned to a CD by Windows image burner or any disk image burner you choose. Or you can download the auto installer for USB Flash drives to run it from a flash drive. Whichever you choose, be sure to download the zip file and extract it. Each Pass consists of 10 tests, each pass checks a different thing and each test checks different things. It takes a minimum of 8 passes to completely check the ram, more passes are better. It will take quite a number of hours to do the test, so it is usually better run over night. To run the test, boot from the media you chose and don't press any keys, the test will run automatically and will continue running until you tell it to stop. It will tell you how many passes it has run and how many errors are found. If it finds errors they will show up as red lines at the bottom of the page and you can stop the test at that point. There is no point in running the test after an error. Any error is a fail. It will take somewhere around 9-10 hours to check my computer with 8 GB of ram. If you have more it will take much longer.

Thanks essenbe for the heads up I was referring to the old one I shall change my ditty to suit:)

Chives worth remembering too that RAM failures can also be due to faulty slots too - so if you have four sticks for example if you do get errors and then test each stick separately say in slot one and no errors come up then it may mean that slot 2 or 3 or 4 may be faulty and that requires a lot more testing

PS Meant to add that this could just mean that the offending slot just needs cleaning and I have a little method I use to do juts that hopefully the sticks will be the problem and not the slots:)

Currently I have 2 4GB sticks, so if it is a slot issue, there are 2 other slots... Though my 212 EVO might be blocking some slots, I don't remember.

So I guess to recap. I need to mess around with a few driver versions and see if that resolves anything. Then I need to run memtest tonight, and if that comes up error free then I can try another PSU. And if the problem persist I can either buy a 760, or send in my card. But at this point who knows, it could be something else entirely.

Chives, I have found in this type error it is not a 'one size fits all' error. They can be caused by many many things. So, there is not 1 solution to the problem. We have a progression we go through to do our best to test everything we can in an effort to single out the troubled part or driver. Even software can cause this problem, so it is difficult to figure out. We will stick with you until we find the problem or throw up our hands. So, don't be concerned about that. We only ask that you stick with us and follow the progression we ask and don't try things on your own, without discussing it with us first. The only real reason for that is we can't be of much assistance unless we know exactly what it going on. We aslo cannot see and hear what is happening with your computer. Therefore, we have to depend on you to be out eyes and ears and let us know everything you can about what is happening. I hope this makes sense to you. If not, never hesitate to ask questions. I never mind anyone asking why are we doing this or your explanations are not clear. Any question you have, please ask.

I would suggest you run the ram test in the slots you are using. If they fail there, it will shed much light on what caused your BSODs, and at that time we will deal with the other 2 slots. As of right now, the other 2 slots are not in the equation as they are not being used, so cannot be a part of the problem. I would also suggest that you monitor your CPU and GPU temps constantly and let us know how they are as you use the computer.

And if you are overclocking anything, please set everything back to default values, at least until we can get you stable.
