My computer sometimes totally crashes. Not even a blue screen, I get a no screen: the screen is black, the power is off. The last 3 times this happened were on 2021-03-20, 2021-07-02, and 2021-07-03. I have configured my computer to try to generate a memory dump (C:\Windows\MEMORY.DMP) file so that maybe the problem can be traced down. Unfortunately, that memory dump file is not always created, nor do I really know how to do Windows debugging. So, I am posting this thread seeking insight from anyone who is a Windows expert. Below are highlights from using windbg to analyse the MEMORY.DMP file from the last (2021-07-03) crash: KERNEL_SECURITY_CHECK_FAILURE (139) A kernel component has corrupted a critical data structure. The corruption could potentially allow a malicious user to gain control of this machine. ... BUGCHECK_CODE: 139 ... BLACKBOXWINLOGON: 1 PROCESS_NAME: System ERROR_CODE: (NTSTATUS) 0xc0000409 - The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application. EXCEPTION_CODE_STR: c0000409 EXCEPTION_PARAMETER1: 000000000000001d EXCEPTION_STR: 0xc0000409 ... SYMBOL_NAME: nt!KiFastFailDispatch+d0 MODULE_NAME: nt IMAGE_NAME: ntkrnlmp.exe STACK_COMMAND: .thread ; .cxr ; kb BUCKET_ID_FUNC_OFFSET: d0 FAILURE_BUCKET_ID: 0x139_1d_INVALID_BALANCED_TREE_nt!KiFastFailDispatch Attached as a text file is the full windbg result of analysing that MEMORY.DMP file. The results above are exactly what I also saw on 2021-03-20, while the 2021-07-02 crash failed to produce a MEMORY.DMP file. Does anyone have an insight into what is going on here? I note this previous post which reported a KERNEL_SECURITY_CHECK_FAILURE, however, its details seem to be different than mine. That previous did have an intriguing reply by Porthos who suggested that other security software can interfere with MBAM. He gave a link which specifically mentions several VPNs. I use Torguard VPN's Windows client, which is not mentioned. So, does anyone see any indication in the windbg result that MBAM and Torguard may be conflicting? I will not hesitate to turn off MBAM's Web Protection if if is problematic. I have had a couple of other strange MBAM issues recently (link1, link2), and in the second one Porthos and I had some discussion about MBAM, Torguard, OpenVPN, and Wireguard. 2021-07-03_windbg_analysis.txt
Please help!In this way, I have to uninstall Malwarebytes. I want you to see the picture.It is this state from today. Is it common?Memory usage rate increases steadily. At the end of the phrase, my pc is frozen by memory shortage. Even if Chrome is not open, it happens. --My pc spec-- OS:Windows7 64bit DSP MB:ASROCK Z87 exteme4 CPU:Core i7 4770 Memory:16GB VRAM:GeforceGTX1070
