BSOD and crashes. Errors 0x1000007E, 0x7E, 0x12B, 0x3B.

Hey all,

I built this computer about 2 years ago, it had a problem a year ago where the motherboard failed on me so I replaced it. Now I think I have another hardware problem. I've reinstalled Windows 3 times now this past month, still constantly getting blue screens/restarts/screen freezes on me. I've ran the Windows Memory Diagnostic tool, which told me hardware problems were detected. This leads me to believe it is the RAM. I've tested both sticks by taking one out and letting the other run, didn't notice anything out of the ordinary.

Not sure what to do from here, I have a general understanding of putting computers together but I've never been able to single out hardware problems. If anyone has any spare time to take a look at this for me, thanks!

two dumpfiles point to memory problems

FAULTY_HARDWARE_CORRUPTED_PAGE (12b)
This bugcheck indicates that a single bit error was found in this page.  This is a hardware memory error.
Arguments:
Arg1: ffffffffc00002c4, virtual address mapping the corrupted page
Arg2: 0000000000000b4a, physical page number
Arg3: 000000000bf14980, zero
Arg4: ffffb08092a6b000, zero

Memory Test.
Please start with diagnosing the system RAM first. You can use the free tool "Memtest86+" to stress test the RAM.

How to run "Memtest" - RAM - Test with Memtest86+ - Windows 7 Help Forums
MemTest86+ - Test RAM - Windows 10 Forums
Make sure you are using the latest version 5.01 - Memtest86+ - Advanced Memory Diagnostic Tool

You can stop the test even if a single error is found during the test. Otherwise continue the test for 8-10 passes and post a screenshot with next reply. 8 passes is the recommended bare minimum but more passes will give better result.

The last dumpfiles of 5 december is:

Code:

 BugCheck 1000007E, {ffffffffc0000005, fffff80f05e2adda, ffffbc017531d7a8, ffffbc017531cfd0}

Probably caused by : dxgmms2.sys ( dxgmms2!VidSchiSwitchContextWithCheck+26a )

Usual causes:* Insufficient disk space, Device driver, Video card, BIOS, Breakpoint with no debugger attached, Hardware incompatibility, Faulty system service, Memory, 3rd party remote control,

Your AMD gpu drivers are from september update to latest version.
Your Realtek audiodrivers are from 2015, see for a newer version

Your Bios version is 0601 from 2014, the latest version is 1503 from 2016/04/08 with improve system stabilty.

The last dumpfile is another one as the one that pointed to dxgmmm2.sys
So i would wait with onboard graphic.

First update this driver rt640x64 Tue May 05 18:21:03 2015 Realtek lan driver from your supportpage.
iI this not stop the bsod.

Then
SFC
Use SFC to check and repair windows systemfiles.

See this tutorial SFC /SCANNOW Command - Run in Windows 8
SFC Command - Run in Windows 10 - Windows 10 Tutorials

Note
If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 times restarting the PC after each time to completely fix everything that it's able to.

If not, then run the Dism /Online /Cleanup-Image /RestoreHealth command to repair any component store corruption, restart the PC afterwards, and try the sfc /scannow command again.
