    Crash Dump Analysis

    Crash dump directory: C:\WINDOWS\Minidump

    Crash dumps are enabled on your computer.

    On Tue 7/11/2017 8:41:15 PM your computer crashed
    crash dump file: C:\WINDOWS\memory.dmp
    This was probably caused by the following module: Unknown (0xFFFFF803143E2348)
    Bugcheck code: 0x133 (0x0, 0x501, 0x500, 0xFFFFF803143E2348)
    Bug check description: The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL or above.
    This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This problem might also be caused because of overheating (thermal issue).
    A third party driver was identified as the probable root cause of this system error.


    One crash dump has been found and analyzed.
    Read the topic general suggestions for troubleshooting system crashes for more information.

    Note that it's not always possible to state with certainty whether a reported driver is responsible for crashing your system or that the root cause is in another module. Nonetheless it's suggested you look for updates for the products that these drivers belong to and regularly visit Windows update or enable automatic updates for Windows. In case a piece of malfunctioning hardware is causing trouble, a search with Google on the bug check errors together with the model name and brand of your computer may help you investigate this further.

    Also, I cannot afford to reinstall Windows as I need my laptop to be in a working condition for the next month or so, due to business reasons.

    On Thu 7/20/2017 2:32:51 PM your computer crashed
    crash dump file: C:\WINDOWS\memory.dmp
    This was probably caused by the following module: rspcrash64.sys (rspCrash64+0x108B)
    Bugcheck code: 0xDEADDEAD (0x0, 0x0, 0x19979B2D, 0x3C2A58ED)
    file path: C:\WINDOWS\system32\drivers\rspcrash64.sys
    product: WhoCrashed
    company: Resplendence Software Projects Sp.
    description: Resplendence WhoCrashed Crash Dump Test
    Bug check description: This indicates that the user deliberately initiated a crash dump from either the kernel debugger or the keyboard.
    This bug check belongs to the crash dump test that you have performed with WhoCrashed or other software. It means that a crash dump file was properly written out.

    Also, booting seems slower now. Taking above 30 secs to boot, which is confusing because I have an SSD installed.
    I believe that the various Antispyware, malware and antivirus programs that I have been running may have deleted some dll files. Now, for some reason, when I press the fn key some of the shortcuts do not work, for example fn + f3 would lower the backlit keyboard backlit brightness, but now it doesn't work. The f3 button performs its function fine alone tho. Is there any program which would allow me to restore my dll files to their previous state, and fix these issues?

    Post #12: One more scan not yet submitted (has the performance of this scan changed in clean boot?)
    ESET Online Scanner

    Please see questions beginning with 10 and provide as much information as possible for each.
    What is the history of malware on the computer etc.?
    What error messages or crashes or problems have you experienced related to 13 and 14?
    How many drives are there?
    Which drive was and was not checked using chkdsk?
    Is there an external drive?

    Was Windows fast startup turned off?
    Is the computer now in clean boot?
    Were you over clocking?
    Was the bios reset?

    Which driver update programs were / are being used?

    Please post a new zip file:
    For any new bsod please update or post a new zip file.

    The ESET online scanner keeps freezing, think ive mentioned this twice before :P
    I havent come into contact with Malware on the PC before.
    Only errors I have are the DPC Latency, where audio and mouse would lag at times, and get the BSOD related to it. IDK if this is related, but my FN + a few F keys dont trigger the shortcut stated, for example lowering keyboard brightness.

    I have a 256 GB SSD + 1TB HDD, and i believe that the SSD was checked. The SSD has all of my programs on it including Windows. The HDD just stores a bunch of database files for my chess programs, a few .exes and Word + Excel docs

    Fast boot off
    Yes in clean boot
    No overclocking, had only OC my GPU once before but didnt do anything afterwards
    No, BIOS was not reset but rather updated to a later version, which has stock settings presumably
    Driver Booster is the program which I use to update and install my drivers.

    Run the Windows defender advanced scan (offline). It will reboot, then load windows defender, then perform a quick scan.
    Run Windows defender in full scan and post an image into the thread.
    Run the Microsoft Malicious software removal tool: Download Malicious Software Removal Tool from Official Microsoft Download Center

    Post a new zip file: BSOD - Posting Instructions - Windows 10 Forums

    For drivers the only sources should be computer manufacturer approved drivers, sometimes part manufacturer, and Windows updated drivers.

    The software programs that install drivers can install anything.

    Attachment 144925

    Why are my FN + F key shortcuts not working anymore, except a few like vol up and down?
    Does it have anything to do with the fact that I disabled all the programs that start on boot?
    Also, pls advise on what I should do next :)

    EDIT: Here is the new zip file for the BSOD checker thing :) Attachment 144927

    Please post the information on the ESET 5 infected files.
    Between normal boot and clean boot is selective boot.
    One or more of the non-Microsoft services by viewing the latency software (before and after) has had an impact on some of the numbers.
    And one of the non-Microsoft services has impacted the keyboard short cuts.
    The automatic driver update software program can install problematic drivers.
    The malware found by ESET: were they trojans, pup's, rootkits? What was done with the files reported?
    The ideal situation to check the hardware is to install fresh software so all of the confounding problems are reduced or eliminated.
    If you cannot do a clean install at this time the next best thing is an in place upgrade repair using the windows 10 iso. This should replace any needed windows dll files.
    Using control panel uninstall Malwarebytes
    Use only Windows defender.
