Hi.

I recently have been having constant BSODs within the past month or so that at first seemed graphics related. I am not sure what the problem is but any assistance would be greatly appreciated.

Specs:
OS: Windows 7 Ultimate x64 SP1
MB: ASUS M4A79XTD EVO (AM3)
CPU: AMD Phenom II x4 965 Deneb @ 3.4 GHz
RAM: 8GB G.Skill Ripjaw Series DDR3 1600 (4x2GB) **Originally 4GB See Below
VID: Sapphire RADEON HD 6850 1GB
HDD: 300 GB Hitachi SATA (Primary) / 1.5 TB WD Sata (Secondary)
PSU: Thermaltake Toughpower 700W PSU

Originally I had thought this to be a graphics card issue because I had a prior GeForce GTX 280 die on me. It was replaced by a GeForce GTX 460 Superclocked and I was still experiencing BSODs.

After that I ran Memtest to test my ram and it came back with no errors. I only ran the test for a few hours so I am wondering if I did not test thoroughly. I ended up purchasing another 4GB and just replacing the original RAM. The machine still continued to blue screen so I figured it wasn't a memory problem and installed the original 4GB of RAM.

I am still continuing to receive 0x1A (Memory Management) and Bad Pool Header errors. Any help that I could get would be greatly appreciated.

Typical Memtest86+ runs should be done with at least 7 consecutive passes.

Nothing here is conclusive so far. I recommend you start Driver Verifier to see if it's driver related.

So far my biggest suspicion is hardware. One of the crashes mentioned code corruption where one solitary bit was lost. Often memory failure is not the cause of solitary bit problems, but they still have the potential to do so, in which case you'll want to run Memtest more. Usually, however, this is caused by either a failing Motherboard, CPU or PSU, or one of the components are overheating.

You can check with overheating using HWInfo with Sensors only enabled. Log two 30 minute sessions: one for idle, and one for high load (gaming, benchmarks, etc.). Send to use for viewing.

I ran Memtest for 20 passed tests last night and came back with 0 errors.

I ran Driver Verifier and restarted my computer. As soon as I hit the Enter key to log in, the machine locked up.

I then ran HWInfo under idle conditions and everything went fine. About a minute into the load test (using OCCT to test) it locked up again and the screen scrambled.

After all of these issues there were no dump files created. The machine just froze up and the screen distorted.

I just ran a stress test on the machine this morning using OCCT again and it ran perfectly well. I played a few games this morning maxing out the graphics and again it worked fine. I am not sure where to go from here.

Your 12V and 3.3V rails are reporting a consistent difference of well over 5% during the idle test. Obviously I cannot see much from the high load test but it did look like it was also fluctuating and increasing. Your temperatures are fine.

I do believe we're looking a pretty bad power supply here. While your brand is a recommended item from TSF, no brand is lacking in the occasional defect. You'll want to get a replacement for it if at all possible.

Alright well I will get a replacement ordered and see if that does the trick. Thanks for all your help.

I'm experiencing a very similar situation (BSOD with MEMORY_MANAGEMENT, BAD_POOL_HEADER, etc.) and I was wondering if you guys wanted the original topic replied to or simply add a new post? Sorry for the simple question and thanks, in advance, for any assistance you might be able to provide this annoying situation.
