    system_exception_thread_not_handled


    Hi all,
    I'm getting the above error and consequent BSOD but ONLY at initial start up if the pc has been powered down for some time i.e overnight.
    I don't get it at any other time, the pc restarts fine after the initial crash, and it never does it whilst using the pc.
    The only other error shown is ksthunk.sys which I believe is driver related?
    All drivers are up to date, no yellow triangles in device manager, I've unplugged all peripherals to no effect, and the BIOS is the latest version. Really driving me mad now, just wondered if anyone had a similar experience?
    PC specs as below:
    Windows 8.1 64 bit pro.
    Asus 990FX MB
    AMD 4150FX CPU
    Radeon HD7950 GPU
    16gb Samsung RAM
    850w PSU

    Many thanks for any help.

    Hi

    The issue you described is generally an indication of a failing RAM module. Yes, some modules works fine when they are warm but may fail when they are cold. Your first steps should be nothing but an isolation test of RAM modules.That is remove all but one module and check how the system works. Repeat this with all modules but make sure the test to be run only when the system is off for few hours and cold.

    Many thanks for your answer, I'll eliminate or prove RAM issues over the next few days. Would running Memtest or similar help?

    I have similar issue and I see same problem reported by quite some people. I don't think its RAM issue for its affecting so many people.
    I sometimes get system_exception_thread_not_handled and sometimes bad_pool_caller.
    I boot once with safe-boot and restart and boot normally it works.
    Desperately waiting for solution...

    Usually memtest won't catch this type of errors. Physically isolating modules is the best way to test.

    I don't think its RAM issue for its affecting so many people.
    Failing RAM is the most common reason for blue screens. Your issue may or may not be caused by that but unless you are going to test each module separately, you won't know it.

    You are correct on both counts - it was indeed a bad RAM module causing the problem. I removed a pair of RAM sticks and problem solved - not sure which of the 2 it is but I'm due to upgrade the RAM soon so can live without both for now, still have 8gb in there.
    Many thanks for your quick reply and correct diagnosis, saved me loads of time
    All the best

Hi all, Recently updated win 8 to 8.1 and a week later on, I'm getting BSOD on bootup. Initially I got system_exception_thread_not_handled and in automatic repair it rolled back few of the installed updates. But no use. Now, sometimes I get system_exception_thread_not_handled and...
