    Could it be overheating? Have you checked the fan and processor for dust build up?

    PSU 750 watts
    Case Basic
    Cooling None
    A computer that shuts down is overheating or is a failing PSU.
    Boot into Setup (Bios) go to PC Health and check the Temperatures and the Voltages. Report here.
    Start the computer with the cover off and make sure all fans are spinning and not blocked by any wires.
    Take a look at the 750W PSU label and report the Make and Model#

    I will look at power supply and report here. I have ordered thermal compound as I cleaned old one from cpu and heatsink. Yes it is basic case but I have 2 x 120 fans on top, one at front and one rear with no OC so I guess they should be enough to reduce heat inside.

    Looks nice and clean. Re-Apply Thermal Paste. Then check Temperatures in Bios.

    I have noticed the CPU temperature shoot from 61 to 78 in idle state. Still in bios screen, could it be that cpu heat sink needs changing?

    Alright, by looking at cpu Temps at idle in bios I decided to go with liquid cooling system and as it was my first attempt ever with liquid cooling I decided to go with this..



    It was pretty easy to install as instruction manual comes with it. After installation and test run I noticed cpu temp sits at steady 25 at idle state.

    Here are few pics of fitting





    I decided to keep fan as intake and fitted tank on top of it. I hope this will resolve any issues with my computer shutting down randomly.
