BSOD windows 8.1 constantly reading error 0x00002a

Hi,
System specs: Windows 8.1
Processor: AMD A6-5200 APU with Radeon(TM) HD Graphics 2.00 GHz
RAM: 8.00 GB
System type: 64-bit

Since the last windows 8.1 patch end of December 2015 i have been getting constant errors, to name a few:
error 0x00002a, thread-exception-died, IRQL not less or equal, system service exception, critical-progress-died, dpc-watchdog-dilation, ntfs-file-system
I have run tweaking.com windows repairs a couple of times and each time as it is cleaning windows errors, windows and pc reboots and I loose everything i'd been working towards cleaning.
It might crash 10 times in a row then work for a couple of hours then start crashing again.

There are many crashdumps related to memory corruption.
DifferentBSOD.
Out of … memory dumps there were …different BSOD error codes.
The differing errorcodes are usually symptomatic of a lower level problem within the system. Theyare usually caused by one of these things:
- faulting (broken) hardware (several different procedures used to isolate the problemdevice)
- BIOS issues (check for updates at the motherboard manufacturer's website)
- overclocking/overheating - You'll know if you're overclocking or not. Please stop at least during troubleshooting.
- compatibility issues (3rd party hardware/drivers)
- low-level driver/system problems within windows (SFC/DISM)
- or even malware

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 7Help Forums
Make sure you are using the latest version 5.01 - Memtest86+ - Advanced Memory DiagnosticTool
You can stop the test even if a single error is found during the test. Otherwise continue the test for7-10 passes and post a screenshot with next reply. 7 passes is the recommended bare minimum but more passes will give better result.

SFC
Use SFC to checkand repair windows systemfiles.

See this tutorial http://www.eightforums.com/tutorials/3047-sfc-scannow-command-run-windows-8-a.html

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

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