    Computer is starting to switch itself off randomly, can run for a few hours and then just switch itself off or run for a few minutes and then switch itself off.

    Yesterday I pulled out my old IDE hard disc drive after it failed and plugged in a new SATA one, was in the middle of the Windows Install and it just turned itself off.

    System specs are:

    Asus P5N32-E SLI
    Intel CPU Core 2 Duo E8400 3.0GHz 1333FSB LGA775 6MB Cache
    Geil Black Dragon DDR2 4.0GB PC6400 Quad Channel Kit 800MHz (4-4-4-12)
    NVIDIA GeForce 8500 GT (512 MB)
    Sony DVD RW DRU-810A
    Sony CD-RW CRX230EE
    Hiper Type R 580W
    Thermaltake Damier V5000A Black Series
    Thermaltake TR2 M21 RX Heatsink Fan for Intel LGA775

    Checked the BIOS and the settings are:

    Voltage Monitor:
    Vcore voltage 1.13v
    Memory voltage 1.90v
    1.2V HT voltage 1.24
    NB voltage 1.24
    SB voltage 1.55
    CPU VTT voltage 1.16
    DDR2 Termination voltage 0.94
    3.3V voltage 3.29
    5V voltage 4.97
    12V voltage 11.77

    Temperature monitor:
    MB: 31C
    CPU: 101C
    CPU Fan: 2518 RPM

    Any ideas??

    101C for the CPU? Too hot.

    Elvandil is right...

    Your computer is automatically shutting down itself to protect cpu from damage...

    Your fan probably went bad....

    Most likely your CPU fan or heatsink.
    It should be your heatsink seeing as your CPU fan is spinning at a reasonable/high speed.
