Need some advice.

So simplest way to describe my issue is that the computer restarts fine, but once i turn it off, it finds that it rather difficult to power the motherboard (thus everything).

Memory checks out OK, dunno about the CPU, started after a long play session of a rather intensive game, so maybe some GPU issue? (PSU is more than capable for what it has to power, though still)

I dunno, regardless, it requires me resetting the bios/some trickery with discharging the MOBO or perhaps just time?

I've reseated all the power cables, though maybe i should try that again? (proverbial pain it is not)

GPU - Evga 980
RAM - 2x Gskill 2400 C9 DDR3
PSU - SeasonicG 750w 80+G Modular

Storage Drive - WD Caviar Blue 1TB HDD
Nothing else of note.

Ok

Have you tried a BIOS update?

Also, try taking the power cable out from the motherboard header and shorting the two pins with a screwdriver

The 24 pin one or the CPU one? both? also which pins are these?

I see, unfortunately behind quite a lot of other stuff, it would mean removing the GPU and a radiator(at least)...though maybe on need to remove one.

What should i be seeing if i short it?

If that is the case, then there's already a button on the motherboard itself.

GPU out, tried all Memory configs with one stick, HDD and SSD both disconnected, nothing.

When it does load, it loads up until the backup bios is loaded and i assume the MB shorts somehow.

I waited 10 mins and its fine regardless.

I assume there's a charge problem here... So that kinda just leaves the PSU and MB being awkward, one of them isnt being nice.

Also note that my monitor acts like it has a signal without the power being there, not sure if this is normal for HDMI cables connecting via DVI...but i doubt it.

Sigh, nope BIOS update did nothing, still ~10 min wait to turn on :|

Edit: 8 min seems to work just aswell atleast...

Gonna go buy a multimeter when a store is open, does maplin stock good enough ones?

I would have thought any Maplin generic meter would do the job for testing rails on your PSU - enough for you to identify a problem if you had one.

Would i be looking for varying currents/voltages or failed rails?

Welp, BIOS values and Multimeter values are more or less the same and within tolerance...

Somehow i no longer "have" the issue, im sure it'll creep up again...i hate computers sometimes :mad:

Also, memory that is supposed to run at 1.65v (insert timings here) and 2400, gives me bit errors in the hammer test unless i use the default 1600 1.5v etc settings

That can be the case unfortunately, with high speed memory, as the motherboard doesn't officially support memory over 1600 MHz. Anything over is classed as an over clocked.

Have you tried running at 1600 with 1.55v or greater as the voltages may need to be raised even at 1600 MHz for stability?

Nah, its fine at 1.5v and 1600, honestly dont mind, stable memory is infinitely more useful than slightly faster memory that has no real gains for me.
