BSOD 0x00000050 atikmdag.sys

So I built a computer in February: i5 2500k, 8gb ddr3 ram, ati radeon hd 6870, 650w psu, 2tb seagate, etc...

Since then I have had constant problems with it blue sceening, I used to get 0x00000050 a lot. After testing my hard drive with about 4 different programs and them all failing I replaced my hard drive yesterday. Today I reinstalled windows from scratch, copied all my data to my new hard drive and I am still getting BSOD's(different ones)

I used to get memory management BSOD's with the faulty hard drive and I am now getting PAGE_FAULT_IN_NONPAGED_AREA on what I think is a graphics card driver...

Besides BSODing explorer.exe sometimes goes into crashing fits and occasionally windows aero will turn off.

I am very stuck on what the problem is and would appreciate some help. I have also uploaded two minidumps and also some info BlueScreenView spat out.

PS: And to make things even more enraging when it BSOD's it makes a loud humming sound through my headset.

We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

If you are overclocking STOP



You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.

To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

They were attatched as text files in my first post(i just renamed them) but here are the zipped up versions.

Unless you were running the game Battlefield 3, it appears you have malware running. The program BF3.EXE tried to write to an invalid memory location. BF3.EXE is a known trojan/worm that runs at startup. You haven't provided enough info to be certain. Follow the instructions at the top of the page please.

I am not sure what you based this on but it is a good idea of course. I will wait for its results before drawing a conclusion

Please download the free version of Malwarebytes.
Update it immediately.
Do a full system scan
Let us know the results at the end.

I think I was looking at the first dump of the last group. I could be wrong but the dx driver and BF3.EXE were clearly shown. I will certainly waive claim to being correct though. Just had a heck of a storm go through in two waves and I was in a hurry to get off the system earlier. It crashed any way even with a UPS. And, I think my satellite box is toast. Really strange incandescent light behavior too--like rapid pulsing.

I better go get my tinfoil hat.

Ok, now I'm getting them in safe mode. Ill post these while I check out that thread and do a virus scan. Also how are you reading the dump files?

PS: Thanks for your help so far, and yes i was playing Battlefield 3 when it crashed one time.

So I got a little mad and ripped out one stick of RAM, it bsoded on that, so I switched to the other and it seems to be running fine now.(5 minutes or so) I'm going to memtest both sticks and see how that goes. If the dumps could confirm that, I would be very happy.

The crashes point to memory problems and a possible corrupt installation of avast!
