Have a htpc with Hauppauge HVR-5500 TV card. 1 front case fan. Bluray drive and m.2 ssd and 4TB storage drive.  Asus H97i-plus motherboard and i5-4690 cpu. Silverstone 300 watt powersupply.  Tonight watching the Rock and computer suddenly shut down.  Unplugged power cord. Left for half hour turned on but wont start. The power light slow flashes like in standby and all fans are spinning. Just wont start.  Anyone seen this. Will look at it tomorrow but just wondering if anyone had a heads up. System 6 months old apart from cpu all parts new.  Have an old power supply I can try tomorrow but not suitable for case but should tell me if thats the problem.

Had something similar recently on a much older system. Wouldn't POST.
Turned out to be a corrupt bios.

I had it unplugged all night. Turned it on this morning and just sits there. Hear the case fan start and power light blinks. Nothing else. So cant try booting usb or cd as no post. Strange just watching a movie and it shut down to this. Just pulled case cover off and cpu fan starts then stops then starts and stops in endless loop. When feel better later will try other power supply

Okay, did try a known good power supply and no difference. Power light blinks. fan spins up, cpu fan starts and stops endless loop and motherboard light green. Will have to remove motherboard later

Disconnect everything except the bare essentials (video/RAM/power) - if it boots, start adding one part at a time until it stops again. Good chance, that last part is the issue.

 

Also, unplug any case fans etc (except the CPU one) - had something last month that refused to boot until I removed an extra FAN, then the system burst into life - fan was shorting out for some reason.

Maybe if we start telling people the brain is an app they will start using it.

removed everything. Then 1 ram stick only. Still the same. Reset the bios shorting the 2 pins out and still the same.

Remove the CMOS battery, Pretty sure shorting 2 pins wont reset the bios on these.. That will however start the PC if you short out the 2 power ones.

the motherboard manual says shorting those 2 pins clears the bios, thats why I tried it

Seen a few motherboards with similar BIOS faults. 
As Coil mentioned removing the CMOS battery might work. 
Depending on the motherboard it can take a while for any stored charge/power to dissipate.  On older circa 90's/2000's motherboards it sometimes took a couple of days.  Not sure what modern ones are like but try over night to start with.

Seeing you've already swapped out the PSU for a known good one, this is generally the point where I decide I've got a spontaneously failed motherboard.

 

It's happened to me a few times but never on a machine newer than 5 years old. If you built this from new parts six months ago, I'd be contacting the shop you bought the motherboard from to say you've got a suspected failure.

yeah the only used part was the cpu. But this is first time I have been watching a movie and computer shuts down and wont restart. Will remove motherboard this afternoon and might even try it with the G3258 cpu

That's worth doing if you're able to - I usually don't have any spare CPUs on hand of the appropriate socket type, especially since Intel started changing the socket with every generation of CPUs.

 

Spontaneous CPU failures are probably the rarest of all hardware failures in my experience, but if you can rule out the CPU then you've literally ruled out all other factors.

 

When you do your test with the G3258, use a different single stick of RAM than you did last time for good measure.
