My self-build is "dead", help needed

    Hi good people. About 30 months ago, with the help of many people and threads on this site, I built a desktop PC that met my specifications. I had been using it regularly until this week, when it failed to turn on for the first time. Pushing the power button on the top of the case did not result in a blue light, as it usually would.

    PC Spec:
    • RAM - 16GB-Kit Corsair ValueSelect PC3-10667U
    • Motherboard - 16GB-Kit Corsair ValueSelect PC3-10667U
    • SSD - Crucial M4 128GB SSD 6,4cm (2,5")
    • Case - FRACTAL DESIGN Gehäuse DEFINE R3 Titanium Grey
    • Processor - Intel Core i5-3570K Box, LGA1155
    • Hard Drive - WD Caviar Green 2TB Sata 6Gb/s
    • PSU - Super-Flower Amazon 80Plus 450W

    The PSU did not seem to be engaged at all, however having tested the PSU separately (using the paper-clip method) it does seem to be working. At this point, I'm a bit stuck. Is this now a motherboard issue? Where should I check next? Is it still possible that the power supply is an issue?

    I don't have access to much other hardware, so am not able to test the various components. Also, I'm not overly versed in this kind of thing so would appreciate any assistance that can be offered.

    Thanks in advance,
    MJS

    Your specific motherboard comes with an embedded power switch and an LED status code indicator.

    Plug the power supply back in and (for jaysus sake ground yourself) try pressing this power switch instead of the one on the case. Does anything light up?

    It's possible it could just be that the button on your case is broken, the cables front the front panel are loose / faulty.

    If you dont have the embedded power switch try plugging the PSU back in to the motherboard, remove the front panel connector to the two I/O pins labelled 'pwr', and then for a brief second join those two pins with a paperclip or screwdriver. If the PC powers up it the front panel button or cable thats faulty.

    Hi both, thanks very much for your advice. I tried the embedded power switch and everything worked well, then once I had hooked everything back up the power button began to function as normal again. I gave it all a little clean out and got rid of any dust so hopefully that's the end of it.

    Lifesavers! Thanks!

    You would think these things would remain stable if you're not messing with the cables, but with fans and HDDs and DVDs spinning there are micro-vibrations throughout the whole chassis. Not to mention normal shaking - people walking by, using the desk it's on/beside, etc. Over thousands of hours of operation, this can shake things loose just enough to stop them from working even though it might seem like "nothing's changed".
