Random BSoD messages at startup and randomly

[lomlobon]

For the last few months I have been having strange stop errors. First they only appeared a few minutes after I started my computer for the first time that day, with many different error codes. After a couple of months of trying different solutions, testing my RAM, installing drivers, flashing BIOS etc. I figured it might be one of my hard drives acting up, and I removed my oldest couple. Since then my computer has been working fine, but today I had two BSODs in a row, with "The video memory manager has encountered a fatal error" and "fltmgr.sys".

Some other random error codes I've encountered:
Memory management
Page fault in non paged area
Bad pool caller
Driver irql not less than or equal

Also, most of the times my BSOD error dump stops at 95, and claims to be completed, but I don't receive a minidump file like when it reaches 100. Sometimes it keeps retrying, and stopping at 95.

I'm attaching my dump files from since a few months ago.

Looks like you still have a hard drive issue, but it is the boot drive

 

[lomlobon]

I'll run crystaldiskinfo and take a look

 

[lomlobon]

Both crystaldiskinfo and SSDlife claim that all my drives are 100% heallthy. Could it be my PSU? I forgot to mention, I have an XFX proseries core edition 550W. Maybe 1-2 added HDDs are too much?

 

[Tmagic650]

It may be worth while to up the power supply to 6 or 750 watts

So I disconnected my extra hard drives, and my computer run fine until today, where I got three BSoDs in a row. First one was a couple of minutes after startup, before I did anything, and the other two times the BSoDs happened while watching a stream and playing a game at the same time. This time I got dump files two times, but the third time the memory dump meter in the blue screen stopped at 95% and claimed to be complete. The given error was "Attempted to write read only memory", but with no responsible file. I run WhoCrashed and got this for the other two:

On Wed 2015-01-07 10:10:00 GMT your computer crashed

This was probably caused by the following module: ntkrnlmp.exe (nt!KeBugCheckEx+0x0)

This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

Could it be faulty RAM, bad drivers, or a hard drive error? I have updated windows and all my drivers, checked my hard drives with both crystaldiskinfo, SSDlife and chkdsk. I tested my RAM a couple of passes, but I might do it for longer. Malwarebytes, MSE, TDSSkiller finds no problems, and I have cleaned my registry with cCleaner.

Thank you in advance.

Go ahead and download Memtest86 version 5.01 if you haven't done so already:
http://www.memtest.org/
Use the pre-complied iso zip file and burn it to a CD or DVD.Start the computer with this disk and let Memtest86 run for at least 7 passes. Any errors mean trouble.The power supply is still suspect at this point

 

[lomlobon]

Memtest86 reported errors after I left it on overnight, so I removed the RAM from slot 3 and tried again, with no problems found with the other stick. My system seems stable so far running of a single 4GB stick of RAM, with no crashes at least so far, so I assume that stick or the slot must have gone bad. I'll just have to test slot 3 when I decide to buy new RAM.
Many thanks for your assistance!

 

[Tmagic650]

Good work! Do you have 4 memory slots total? If so, you might try filling all 4 slots when you have time

 

[lomlobon]

I do, would a 4x2GB setup be better than 2x4GB? Or do you think I should test all slots for faults?

 

[Tmagic650]

Normally you would either use 2 slots or 4... not 3. So either of your setups would be fine. I really don't think any of the slots are bad. The motherboard manual will show you the proper memory configurations

 

[lomlobon]

Oh yeah, with slot 3 I meant slot number 3, I use slot 1 and 3, because dual channel uses either slot 1 and 3 or 2 and 4 on my MOBO. I used only 2 slots of RAM.

 

[Tmagic650]

That's good, so you may have a bad memory stick. Bad memory is much more common than a bad memory slot
