    Well, what are the parts of PC, especially that PSU?

    And does it need complete power cycling of PSU (disconnecting wall plug/using PSU's switch) to try booting again or does it try boot again by pressin power button of case?

    it can be instantly powered back on, its an xfx 750w something (XFX XTR Series 750W 80 Plus Gold Fully Modular Power Supply), ive already contacted ocuk and they seemed to think its the psu as there was some issue with psu's by xfx where that was happening so they instantly offered an RMA and to exchange it

    Update: new PSU came and its still doing it, swapped the gpu as i had another one and assuming there cant be anything else causing it its got to be the motherboard then right? its just it doesnt restart it just instant powers off without any warning and nothing physicaly loks wrong with it but im out of ideas otherwise

    How long after starting does it switch off?
    Might be the heatsink has come loose? or dried out tim?

    it stopped doing that and went back to running once its powered up but taking 20 or so presses to actually boot up. so far ive just let it run and not turn of for 4 days and its running fine. will need to RMA but cant face being without a real computer and going back to 15inh laptop
