Multiple BSOD's , multiple memtest86 errors, memory management BSODs

Today right after I installed a rather demanding flight simulator p3d and played it , I've had multiple BSOD's.
At first I uninstalled it and cleaned everything up , had no problems for a while , then I started getting blue screens in other games ( less demanding from steam) and so I ran a Malwarebytes scan which quarantined and deleted a generic.malware. ,
The problem still persisted so I installed CCleaner which cleaned my registry and apps , after that I opened Malwarebytes which was unresponsive , so I uninstalled it which led to another bsod . it also persisted while browsing , tabs would show me the folder with the face ( not the one with crosses for eyes) after Wich I would get blue screens .I ran the windows memory test and the memtest86 which both found problems ( ~4000 erros memtest86).


Not sure whether I should change my ram or it's a software issue.

P.S
If it's a software issue I have no problems losing data as all of it is on drive

Also, the graphics card is 1 month old and has driver updates which I haven't done

PC SPECS
I3-3240 3.4 ghz ( no overclock)
4 gb ram ddr3 1330Mhz (

Also it asks me to check disk C while booting + when trying to update the Nvidia drivers there was a Microsoft c+++ error
