PC no longer works

[spyder]

Hello All,

 

Little background: 

 

I built my own gaming rig back in the summer of 2015.

 

Some specs:

i5-4690k 

hyper 212 evo

16gb hyperx ram

gtx 970 strix

gigabyte z97p-d3 mobo

evga 650 g1 psu

1tb hybrid drive.

 

Problem: 

Whilst my brother was playing games on the machine, it suddenly switched off completely. 

 

When I hit the power button, the cpu fan and gpu fan spin briefly for one second and then turn off. 

 

Solutions I have tried so far:

- Double checked all the power cables from the motherboard to psu, they are all seated correctly.

- removed ram and placed one stick in, tested different ram slots 

- removed gpu

- removed network card 

- tore out the entire PC from the case and rebuilt it, (minus re installing the cpu and cooler since the hyper 212 is a real bitch to mount) 

- tried powering machine using screwdriver 

- reseated the cmos battery. 

 

 

Does anyone know what might possibly be the cause?

Overheating?

[Fabian Lioner]

Were you overclocking?(I see a Z motherboard so technically a bad overclock could harm your system)

If you were overclocking:

Did you overclock the ram?

Did you change the CPU voltage?

 

Does it turn on without the 970?

 

Can you hear your hard-drive spin?(Or is your boot drive even working?)

No bios?(Post code?, any errors , maybe set your bios to default)

Sounds like your psu is triggering a fil save. Try a ather PSU and das it maby smell like its burning

No overclock was ever set. 

Cant boot at all therefore go into bios, no post codes 

hard drive doesn't spin either.

I was thinking along those lines too, possibly dead psu but don't have a spare on site, might have to order a new one or even rma it.

System has been running fine up until now. It has adequate cooling solution, everything was running at stock, no overclcok was ever applied. All parts look physically fine and no obvious signs of damage.

Definitely try to test a different PSU.

Would like to try but need to be 100 percent sure and I don't want to end up spending money on unnecessary parts in the event something else is causing the fault.

Do you know anyone else with a computer? Just ask to use theirs for diagnostic test quickly.

it could be the mobo

Unfortunately that's going to be a bit difficult.

I was thinking along those lines too, you see the graphics card has a little indicator light which turns on and stays on as soon as I switch the psu power on. That means power must be flowing in some way.
