  1. Hi there, my online friend's PC has been randomly crashing during use. I'm trying to help him out, but I can't find out through these minidumps what exactly is causing the problem. Here are 5 of his most recent dumps, any info appreciated thank you.

    Does your friend have any overclocked hardware, particularly his cpu?

    Nope it's all stock clocked hardware.

    The reason I asked is because of the error codes.

    Three are 0x101: CLOCK_WATCHDOG_TIMEOUT
    This indicates that an expected clock interrupt on a secondary processor, in a multi-processor system, was not received within the allocated interval.

    The other one of importance is 0x9C: MACHINE_CHECK_EXCEPTION
    This is a hardware issue: an unrecoverable hardware error has occurred. The parameters have different meanings depending on what type of CPU you have but, while diagnostic, rarely lead to a clear solution. Most commonly it results from overheating, from failed hardware (RAM, CPU, hardware bus, power supply, etc.), or from pushing hardware beyond its capabilities (e.g., overclocking a CPU).

    Honestly, this is a very difficult error to work with because as it says a clear diagnosis rarely comes forth and I have never seen a minidump with this error code that gave a definitive answer. I know IT techs that don't like working with it. What makes it so difficult is that it can be any hardware in your system -- and I mean any. Your dump simply cited hardware as the issue and nothing more definitive.

    Here are some of the causes that were determined to be the source of 0x9C errors from posters here and abroad: NIC, DVD/CD drives, dust build up around the CPU that caused overheating of said CPU, bulging capacitors hidden by heatsink, video card, psu, motherboard, and external harddrive connected by USB.

    In regards to the 0x101 error please see the following link and I recommend you follow the diagnostic advice:

    Thanks a lot for the response. I'm going to have him run prime95 and check his core temps 1st, then work through stress testing all his other components until I get a crash, or memory errors. I'll keep you posted if I get an answer.
