    Having some probs with booting my desktop pc up, it fires up but then powers down after 5-10 seconds then restarts. Any ideas?

    PSU is only a few months old and should be powerful enough to cope with what I have? I tried changing the CMOS battery a few weeks back which seemed to work but on trying again last night it was back to square one again.

    What PSU (wattage) is it? And is it powering down at certain times (e.g. during gaming)?

    It could be overheating if it keeps shutting itself down. If you built it yourself, did you use thermal paste? It's shutting down a bit quick for that though.

    You can get a PSU tester for pretty cheap if you think it might be that.

    Just googled it and few sites saying it could be the power supply ...

    Its a 650w Corsair and has never powered down after completing boots so doubtful it is overheating

    Yeah it has thermal paste on CPU etc but its immediately on switching on rather than midway through use.

    Memory can be a pain, if you've a couple of sticks in take one out at a time and test.

    I had a laptop in a few weeks ago doing exactly the same. After doing all the usual, taking parts out and testing it was just Windows 10, more than likely an update gone wrong. Try booting with Windows 10 on a memory stick to test to see if it stays on

    I'd pick yourself up a cheap tester, 650w should be more than fine unless you have some top end stuff.

    Other free tests: check none of your cables are loose, check there are no loose screws rattling around shorting it, try running it on bare bones (remove graphics card if you have onboard, remove memory down to one) so that it needs limited amounts of power and see if you still have the same problem.

    Should be alright. If it's a self build, is it anything rudimentary like a missing power connector? Does your motherboard or graphics card require an additional power via a 6-pin connector (I often forget to plug these in)?

    What post beeps are you hearing

    Test." It is a diagnostic program built into the computer's hardware that tests different hardware components before the computer boots up. The POST process is run on both Windows and Macintosh computers.

    Sounds like it may not be completing POST (as above) disconnect everything one at a time (including keyboard)

    my favourite all time computer error message comes during POST.

    Faulty keyboard or keyboard not present. Press F10 to continue.

    They should - but not everyone plugs in the speaker for it - check motherboard manual for details.

    Is there a little screen on the motherboard? Some have that and it will display an error code.

    It does sound like a potential thermal issue. What CPU is it and what cooler?

    And the fan is spinning properly and everything?

    Although that should have enough surface area for more than 10 seconds even without a fan.

    I’d peel everything back, take all the components off (drives, RAM, GPU), reseat the CPU, use new thermal paste (clean the old off with some kitchen roll) and put a single stick of RAM in the furthest away slot from the CPU.
