Mobo issue?

I'm at a loss as to what else could possibly be causing this, but I've no experience of mobo issues so unsure whether it is actually the problem.

Board is a Gigabyte Z77-D3H, I used to power it up and down via sleep (W7 64bit) with no problems, then out of the blue it started to get random whether or not it would recover from sleep properly, it would either work faultlessly or I'd get the error beeps and it would restart before actually getting anywhere and give me the whole "Windows did not shut down correctly" spiel.

It then slowly progressed to where I am now where not only will it not restart from sleep but it won't restart from a total shut down either, the only way I can get it to boot is by turning off the PSU for about 10-15 seconds and then it boots as normal with no errors.

Once booted everything works 100% flawlessly.

Things I've tried- replaced the PSU, fresh install of windows, resetting CMOS, flashing BIOS, unplugging all USB devices and network cables. None of this has made any difference, so I'm left with thinking this is a motherboard issue, it can't be a BIOS setting I'm unaware of because I've flashed and reset it so many times now.

This is a pain in the neck now because normally the PC case is hidden out of the way, hence me using sleep a lot, at the minute I've got to have the case dragged out into the room so I can reset the PSU from the case switch before every boot.

Rest of spec, if it helps, is:

Be Quiet Pure Power 630W PSU
Gigabyte GA-Z77-D3H mobo
Core i3 2100
16GB Patriot Viper Xtreme DDR3 PC3-12800C8 1600MHz
64GB SSD for OS and games
2TB HDD for storage
GFX VTX3D 7870 Black
Dell 24" LED 1900x1200 connected via DVI
W7 64bit Home Premium

Any ideas?
 
are you using xmp for your memory? sleep/resume usually is memory or settings related as it saves and resumes the sleep state to and from the memory,still could be a bios bug too

try with 1.08v cpu/vtt see if that helps
 
Sorry, I'm a noobcake, I have no idea what any of that means.

Even though sleep is memory/settings related, would this cause the shut down/restart issues also? I'm less bothered about sleep issues now and more bothered about why it wont boot from shut down without a PSU reset.

look in the bios,press delete at splash screen,then in the bios look for and enable xmp for your memory

and look for cpu/vtt voltage and set to 1.08v from stock 1.05v

then see if its any better
 
Ok will do.

Just checked the mobo manual and I didn't notice this before, it says it only supports 1600mhz RAM on Ivy Bridge chips, could this be an issue? I would have thought if it was I would have had issues long before now.
 
are you overclocked or stock?

1600mhz is just the stock ram freq it will support much higher

maybe flash to latest bios,use a usb stick and qflash f8 in the bios

After some reading I've come to the conclusion this board is a bit crap. It's never been that good, but these past few weeks it's been a nightmare, I'm tempted just to bin it and go for something else.
 
Thanks for trying Wazza, but a bios update has changed nothing unfortunately.

It's possible it's some bios setting that I don't understand or don't realise effects shutdown/startup. Not sure why I'm not able to alter the RAM settings like you suggested either.
 
Yeah more noobishness on my part, I was expecting a drop down menu like all the other settings where it states 'auto'. Didn't realise you had to manually type in the voltage.

Still hasn't made any difference though.
 
Can you also try with pwm phase control set to extreme performamce and vcore voltage response set to fast

Still could be a BIOS bug that needs fixing,I remember going through similar with my x58 board
 
Tried those as suggested, still no luck.

Things got decidedly worse not long after I upgraded the gfx card, I may try swapping it out to the previous one just to rule it out.

I must admit, so far my experience of Gigabyte boards and AMD gfx cards has been atrocious. I've another build in the planning and I think I'll avoid both.
 
Probably doesn't interest anyone but this fault is cured for now. I'm not 100% sure what sorted it, but the last two bios settings I altered where the ones relating to on board graphics standby, both were set to disabled and I set them both to enabled.

It doesn't really explain why this problem started out as a random one and then developed into a permanent one, you'd think it was either working or not, but for now it's fixed at least.
