So my 2016 build PC has finally decided it didn't want to awaken when I set it to sleep yesterday. I am pretty sure the motherboard has given up to go to a better place. Sequence of actions was, sleep PC with only web browser open, PC didn't wake on mouse/keyboard input so tried power button - also no good - then hard powered off and back on. The other alternative is that my GPU has gone or probably knowing my luck both.

Spec:
Processor - i7-5820k
Mobo - Gigabyte X99-SLI
Graphics card - Radeon R9 390
RAM - 16GB Corsair
PSU - EVGA 650 GS

Symptoms:
On power button, case fans spin up but GPU fans do not. HDD appears to spin up. No beeps. Motherboard has an ambient LED strip that doesn't light up but I am unsure if this was disabled in BIOS as it doesn't match the cooler colour. Motherboard light near ports doesn't consistently come on then go off but if the power is fully discharged it comes on then 'pops' out within a second - I am not sure if this is normally constantly on. No LEDs on GPU or other cards that I am aware of. PC has been in surge protected extension and the protection LED is still lit, we did lose wardrobe lights yesterday too but I think this is a coincidence and my son probably pulled their lead out of the driver but haven't moved the unit to check :D

Troubleshooting already completed:
Removed RAM - no beeps etc, no post. Installed 1 stick of RAM only - no beeps, no post.
Removed GPU - no beeps, no LEDs, no audible or visible sign of post (but no display to view it on), no fans on card
Moved GPU to another PCI slot - nothing and no fans on card
Removed connector to case power on and bridged to power on in case connector was stuck - nothing.
Used alternative power port on PSU to attempt to power GPU - nothing.

Please can someone help me confirm the worst or provide alternative troubleshooting steps? I haven't got any spare equipment nor know anyone local who could try alternative graphics card in or anything? Let me know if you need any further info.
 
Without changing parts your just guessing.

Case fans spinning power there but fans on gpu don't run would indicate gpu , not diffinative as the psu mite not provide enough juice if faulty.

It's a difficult call.
 
I will test the PSU with a multimeter at some point in the next few days and see if I can rule that out. The bit that's concerning me about the board is the LED that occasionally comes on but not on every power on. I can't see any damage to the board visibly but I haven't removed it from the case either.
 
Tested the PSU and all voltages are fine. Supply to GPU is fine too so I'm happy it's not the PSU.

Annoyingly the motherboard has no power after the test and I checked I didn't bend the connector pins with my jumper (trusty paperclip) but I'll try a new cable later in case that was the case.

Starting to think this is a good excuse to persuade the wife a new £1500 computer is a good idea :cry:
