    Hi,

    Hope you can help.

    I have recently built myself a PC (Windows 7, i5) and it's running fine except for one problem. Every now and again, when I've been away from it, I find that it's reset itself. I don't think it's overheating as the machine has two extra case fans and the temps seem fine.

    How should I go about starting to investigate this as it has never reset itself while I've been there.

    Regards,

    C h r e d g e.

    First thing to do is check the event logs. That would give you an idea of what could be causing the rebooting.

    turn off the auto reboot
    control panel /system/advanced/startup and recovery settings
    then untick the auto reboot box
    post any bsod error messages the computer freezes on in full

    what are you running
    video card brand and model
    cpu
    m/board
    ram
    power supply
    brand
    model
    wattage

    check the listings in the bios for 12v line voltages and temperatures and post them

    Hi,

    Thanks for your help guys.

    Some info for you.

    GPU - Radeon 7870
    CPU - Intel i5 3470
    MOBO - MSI Z77A-G41 Intel Z77 Socket 1155 DDR3
    RAM - 2x8GB Mushkin Enhanced BlackLine Frostbyte
    PSU - 500W Corsair Builder Series 500CX 80PLUS Bronze Power Supply

    *In the event logs, what is it that I'm looking for? This is ticked in the advanced settings so I imagine there would be something there?

    Thanks again,

    C h r e d g e.

    As for event log, check for items with a red X, with an "Info" entry near it stating that the last event log entry was stopped unexpectedly (or something similar to that).

    Hi,

    Thanks again for your continued help.

    Having found/checked the event logger I have discovered a number of 'warnings', 'errors' and 'criticals'

    Warnings are (mostly) - DNS Client Events
    Errors come in various 'flavours' - Service Control Manager/BugCheck/Schannel/
    Critical was all - Kernel-Power

    Each of these types comes with a short description of what the problem was, how do I actually resolve all these?

    Thanks again,

    C h r e d g e.

    Check the "Kernel Power" entries, and there should be an Event ID, and a Source. Post that information here, or a screenshot, and this should help out.

    Hi,
    Thanks for your help, here is some info for you;
    This problem has been discovered while initially investigating why my PC was occasionally shutting down on its own. The PC would be left for some time and when I’d come back the PC was off. This is a new PC which I put together myself, there didn’t seem a specific time when this ‘shutting down’ problem began. After asking on other forums some people speculated that the problem may be connected with the PC going to sleep (I was having another issue whereby the PC would go to sleep by I was never able to ‘wake’ it).

    Windows 7 – service pack 1
    GPU - Radeon 7870
    Processor - Intel i5 3470
    CPU – 3.20GHz
    MOBO - MSI Z77A-G41 Intel Z77 Socket 1155 DDR3
    RAM - 2x8GB Mushkin Enhanced BlackLine Frostbyte
    PSU - 500W Corsair Builder Series 500CX 80PLUS Bronze Power Supply
    500GB HDD

    Some event log info from the latest kernel power entry:

    Product
    Windows Operating System

    Microsoft-Windows-Kernel-Power

    The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

    Is the system creating any dump file? C:\Windows\minidump If so, please copy minidump to the desktop, compress it and upload it here.
