    Custom build spits Machine_check_exceptions and Clock_watchdog_timeout


    Two weeks ago I build a pc and from the start I've been trying to diognose what's wrong with it. It crashes at seemingly random times while running nothing special at all (steam, chrome, spotify, bittorrent). Most of them are Machine_Check_Exceptions, but sometimes it's also Clock_watchdog_timeouts.
    At first I thought it was a driver problem. So, I used Driver Booster to download new drivers. That did not solve the problem and actually made the system very unstable. After that I did a format and just waited until windows started installing the drivers. This worked fine at first, but the same problems came back after a few days. I've updated the bios to the latest version and never done a OC on the machine. A few things that came to my attention while researching, but don't seem likely to be the problem are:

    • When putting the thing together I bend one of the USB3.0 port pins. I have bend the pin back and inserted the cable into the port. The ports in question work well and send over data at speeds I would expect.
    • The CPU cooler I've chosen is very heavy and could be installed improparely. This was one of the things I've found on wikipedia when researching this. However, the CPU runs idle around 35-40C ( 95-104F). I don't know what the temps are when the system crashes, though.
    • I have run memtest86+ for 9h and it gave 0 errors

    While writing this post (~30min), the system has had two Clock_watchdog_timeouts while being idle. Sometimes, the BDOS data collection gets stuck around the 60% mark.Attachment 61512

    Do you use the USB with the bent pins?

    The 0x9C is similar to 0x124 which is a hardware error.

    It is recommended to not use ports where the pins are bent/broken

    I unplugged the cable. After ten minutes I got a Clock_watchdog_timeout.

    I didn't say it was the cause, only that it is recommended to not use it as it may cause more instability.

    Are you running the tests suggested?

    Yes, I've ran memtest86+ before without error and I did chkdsk on my drives. Windows fixed an error on my mechanical drive. After that my mechanical drive started to make a strange noise. It had a rythm to it and it kept repeating that rythm. Just to be sure I turned of the pc.
    Still running the other test.

    I do remember something about Prime95 having a bug with skylake processors, so I don't know how useful it is to run this.

    Another question for MemTest86+, how many passes completed with Memtest86+?

    I remember that too, you can run the IntelBurnTest fortunately

    I think about 5 or 6 passes, but I'm not sure. I only know for sure it was about 9h.
    Thanks for the tip, I'll try intelburntest.

    You didn't read my suggestions?

    In my first post of this thread I am clearly suggesting a couple of tests to try including IntelBurnTest.
