Solved BSODs, Random times, random error messages.

[Heldelance]

Hi all, first off, thanks for reading this.

Basically, my current build is about 2-3 years old, the newest thing being my PSU (which I replaced after several issues with the GPU drivers constantly crashing, turns out it wasn't the power anyway...)

For the past few weeks, I've been having issues with it. At one point, the computer refused to start (it would power up but the k/b and mouse lights wouldn't turn on), I seem to have solved it by moving my RAM (slot 3 looks to be buggered).

I kept on getting BSODs, at random times and different messages. I could be playing, watching a movie, or even letting it sit idle, and it'd BSOD. Temps for both the CPU and GPU are fine, GPU hits about 70 and CPU tops off at roughly 40C (when stress testing).

I tried running Prime 95 + Furmark, no crash funnily enough. Done the RAM tests, 7 passes on both sticks, no issues.

The error messages I've gotten are, Bad_Pool_Header, Memory Management, System Service Exception. The most frequent one is the Memory Management one.

I'm at my wit's end here. I've updated my Mobo drivers, GPU, etc. I'm hoping that someone might be able to make heads or tails of the problem and give me an idea of what to do.

Forgot to attach the dumps. Here are the most recent dumps.

The one labeled "Dumps" are just the minidumps I pulled directly from the folder.

The second one is the log created by that DM Log Collector program.

Not sure if this has any bearing on what's happening, but it seems that the whole "startup" issues are back, not as often, but still there.

Sometimes it'll get stuck right on the BIOS screen (after checking all the HDDs). Other times, the power will go on but the lights for the peripherals won't go on (they usually do when it's normal).

Windows told me to do a Startup Repair just last night (it froze and restarted when the Windows Logo was doing its thing). Once the repair was done, I checked the Diagnosis and Repair details.

It said that the root cause was "Unknown Bugcheck: Bugcheck 19. Parameter = 0x3, 0xfffff880023e2e90, 0xfffff880023e2e90, 0xde684100de6841.

Any chance someone could help me out here?

I've wracked my mind for solutions but I'm still drawing blanks. I've pulled out and reseated everything (in case it's hardware though WhoCrashed says otherwise for all the BSODs), I've run Prime95 and Furmark at the same time (again) but it doesn't BSOD during that. Last night, I ran that memcheck thing (After the whole Startup Repair thing) and it did 7 passes with no errors.

If I can help it, I'd rather not rebuild this PC yet.

Follow these instructions on how to change to Kernel Memory Dumps.

Once changed wait for another BSOD, then upload the new dump file to a file sharing website like OneDrive.
The new dump file will be located in C:/Windows/memory.dmp.

Don't zip it up as it corrupts the dump file by compressing it.

You could try Memtest as there are some indications to bad RAM.

Memtest86 will test your RAM

   Information

Run Memtest86 for at least 8 passes so we get enough information to confirm that your RAM isn't failing

Thanks so much!

I'll get on that once I finish work. Should I run Driver Verifier as well? I've been told it causes BSODs to happen a little more frequently.

I'll re-run memtest overnight as well. A question about that though, when I read the logs from WhoCrashed, none of the error messages say it's hardware. They're all saying that it's probably the drivers.

I am planning to rebuild the entire PC eventually though, I'm just waiting on funds to replace most of the hardware (except for the HDDs, I'm going to test them to make sure they're all good).

 

[Thedoctor44]

Well Driver Verifier doesn't always help, I normally ask someone to turn it on when we know an unidentified driver is causing memory corruption.

WhoCrashed isn't very reliable so I don't go on that, don't forget that drivers communicate with hardware so if it's faulty RAM there isn't really a driver for it, depending on which addresses are faulty different outcomes are received.

 

[Heldelance]

I think that if you can answer this thing, then it definitely isn't a driver issue. I don't think it'd be an HDD issue as well. I'm actually thinking the Mobo's gone.

I just spent 15 minutes trying to turn the damned thing on. The tower's lights come on, fans spin (normal speed from the sound I hear). However, the keyboard and mouse lights which usually flash then stay on during boot, they don't even go on.

I had to keep powering up and down (it's not the PSU, I actually replaced it previously). I've tried the PSUs on another PC and they're fine. Does this mean that it's the Mobo that's gone? Or could this issue stem from one of the parts plugged into the mobo? I was under the impression that unless it's the mobo itself, the mouse and kb will still light up (even if the screens don't come on if it's the GPU).

Last night, I was actually able to use the computer without an issue, it seems that it has its good days and bad...

 

[Thedoctor44]

Right, did you test your RAM?
RAM could be the source of the issue and from the dump files it looks promising.

A faulty motherboard is always a possibility that unfortunately we can't test.

You might have to bite the bullet and start replacing as there is no way to test it.

 

[Heldelance]

Righto, so I tested the ram on 2 computers, there it passes perfectly.

Since I last wrote, I've only had one BSOD, a memory management one I think. The main problem at this point was that my computer would just freeze at times, it wouldn't boot (tower lights come on and everything spins up but screens and peripherals are still off). However, it has, for the most part, been running totally fine.

I'm guessing it's the Mobo, and as you said, there's no real way to test this. I'll just have to persevere until it finally kicks the bucket or I finally get the money to replace everything.

Thanks for the help though.

Upload the dump file(s) anyway, I'll have a look

 

[Heldelance]

I've got Google Drive on the PC already. I've copied the dump to the Drive folder but I can't make heads or tails of how to share it. The "Share" option is greyed out.

 

[Heldelance]

Ok, found how to do it. Please PM me an email address I can share it to, I don't know how to make it into a link...

edit: Nevermind, fiddled around and found it.

The dump file is completely corrupt.

You will have to wait until you can get another one then upload that.
