Random but frequent BSOD. 4e, 1a and 50.

[Lukeqz]

Specs:

OS: Win 7 Home Premium

CPU: Intel Core i5-2500k 3.3GHz Quad Core

GPU: Radeon R9 290 4GB - This has been replaced since the problem started. Used to have a Nvidia GeForce 560ti 1GB

RAM: 8GB Corsair PC3-12800 1600MHz DDR3 Memory (2 x 4GB sticks)

Motherboard: Asus P8Z68-V LE Motherboard

PSU: Corsair Ultra Low Noise 600W PSU

For at least 6 months I've been getting BSODs frequently, 1 to 2 a day while I'm at my computer, and occasionally while I'm away from my computer.

It's mostly been 4e and 1a. I only saw the 50 today, and i'm sure I seen a couple of different ones over time that I can't remember.

I did a 12 or so pass memtest a few months ago, and I have checked all my drivers.

Additional information is required - not just the .dmp files.

1. Download the DM Log Collector application to your desktop by clicking the link below

DM Log Collector.exe

2. Run it by double-clicking the icon on your desktop, and follow the prompts.
3. Locate the .ZIP file that is created on your desktop, and upload it here in your next reply.

Is this what you're looking for?

Sorry, I let it run and that's what it gave me.

 

[Golden]

Run it again as Administrator, and wait for it to finish. Its currently incomplete.

3rd times the charm?

 

[Golden]

Thats better.

Could not read faulting driver name
Probably caused by : memory_corruption ( nt!MiAgeWorkingSet+425 )

You need to rule out memory problems - run MemTest86+ (note the +) for a minimum of 8 consecutive passes:

This was what I ran a few months ago, and that problem hasn't changed, I know I did around 12, way over 8.

Please do the following:

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Driver Verifier will cause your computer to run very sluggishly - this is normal. What it is trying to do is force your system to BSOD and isolate the offending driver/s. When it does, reboot, disable driver verifier, reboot as normal and upload the new dmp file/s here.

I recommend creating a system restore point before turning on driver verifier:

If your system fails to boot to desktop once driver verifier is enabled, turn it off by booting into Safe Mode:

So I just ran the driver verifier for about the last 36 hours. I had no crashes during that time, but when I disabled it and went to restart I got a C9 BSOD.

bump

There's no need to bump - you just need to be a bit patient.

Create a System Restore point, then uninstall ALL ASUS applications/programs (e.g. ASUS GPU Tweak etc. etc.) from your system. Reboot and monitor for further BSOD's.
