Windows 10: Regular BSOD when using computer, MACHINE CHECK EXCEPTION 0x9c Solved

    Regular BSOD when using computer, MACHINE CHECK EXCEPTION 0x9c

    Since the 1st of this month, I've been getting Machine check exceptions randomly after booting from 3-4mins to up to 30-40mins after initial boot. This computer hasn't had any hardware changes for almost an entire year since I've built it nor has there been any BSOD until a few days ago.

    What I've tried:A motherboard BIOs update as well as a CMOS reset and default settings in the motherboard.Opening the case and using compressed air to clean the machine.Reseating the ram and the CPU stock cooler(I didn't take out the CPU)I went to my motherboard site and updated all the drivers on there.I've tried system restore but there is no improvement.I've tried Driver Verifier and I got a BSOD for "Driver_Verifier_iomanager_violation" using whocrashed says its the driver iomap64.sys.

    What I've haven't tried:mem86+ test.
    A full virus scan of my system(PC keeps BSODing before the scan can finish).

    Notes: Safemode with networking works fantastically with no errors.
    The only recent hardware change is between a Poker3 mech keyboard to an old dell kb212 keyboard and back.

    I'll appreciate it if someone can take a look at my drivers and dump logs.

    WHEA error for a MCE fault
    This could point to hardware problem with your CPU but more often also motherboard software and monitoring software can cause this kind of BSODs.
    In this case it's an internal unclassified error, which means it's not publicly documented (which is ironic given it's "unclassified"). However, yes, it's clear you're dealing with an internal CPU fault and not one that could be generated by bus issues or any other external factor other than heat and voltage. Though make dead sure motherboard software isn't interfering; sometimes mobo software will generate CPU faults of this sort because of bugs in their CPU drivers.
    Other than that, no, there's really nothing else you can retrieve from this.

    Update all your Asus utilities software (a.k.a. Asus Bloatware) to the last version or remove them.

    Imdisk has drivers from 2015, update it (or remove?)

    Also see if a newer driver is avaliable for netr28x Fri May 29 13:26:59 2015, probably your ASUS PCE-N53 300Mbps 11n dual band Wireless PCI-E card

    After a few days of tearing out my hair, I finally solved it. In short it was Intel's graphics hd driver.

    It was tricky because the bios disables the intel graphics card when a discrete graphics card is installed. Its usually unnecessary to uninstall that driver since the hardware is supposed to be deactivated. Intel's installer does not allow updating it either. In short, it was the only driver that i didn't update since i thought it was irrelevant. I used a program called "Display driver uninstaller" to completely remove the intel graphics and the computer stopped BSODing. I've been running an instance for a least 12 hours without a single BSOD.

    Tip: i only considered the intel graphics card when I ran a live boot of linux and found that to be crashing as well. I removed all my pcie devices(graphics card, network card) so i made a gamble on that.

    A few notes: When uninstalling the Asus utilities (AI Suite 3), the uninstall leaves a lot of things behind. You would want to do a clean install of all the bloatware and services. Check the asus folder in program files, C:\ProgramData, as well as the registry. Be extra careful when uninstalling USB 3.1 boost as it could disable all your usb I/Os.

    I'll update the thread in a few days after I confirmed it to be solved. Thanks lifetec for the suggestions!
