Tried to turn my PC on tonight for it to just flash and then turn off with only motherboard lighting illuminated.

Swapped sticks of ram and checked case power buttons, all OK but same issue, wont boot.

Tried old PSU, system now boots but BIOS will not recognise any of my hard drives?

Is it possible for a bad motherboard to kill a PSU? We are talking Asus Crosshair VI Hero & and XFX 1250W Black edition running ryzen and a 1080ti

Any suggestions welcome and thanks to anyone who can help

Edit: It says All Eight sata ports are empty which is of course not true, I have 6 of them plugged into hard drives

it is possible for a power surge to kill several components. Having said that that calibre of PSU should really protect your system although its never guaranteed.

In cases like this you have to be methodical.

unplug everything from the motherboard, if you can test components in another system that makes life much easier.
I would try the HDDs in another system first to verify they aren't toast. do you have any spare drives you could use for testing ?
 
Could I be right in thinking the XFX could be preventing itself from booting the system up because it detects a problem with the motherboard, whereas the test PSU i am using doesnt have this feature, which allows the system to boot up?
 
I take it you tried resetting bios to default and unplug all but 1 of the drives. Also sometimes having USB devices plugged in when you boot can cause this problem.
 
So having tried to rectify this problem, I have since found that disconnection of all hard drives but one seems to cure the issue.

But if I reconnect them again afterward, it does start ok the next few times, then proceeds to fail.

I'm thinking myself this must be more related to unreliable power supply, but I still cant be sure that its not the motherboard. Any ways to test here more than what i've done?

Also putting the computer to 'sleep' rather than completely turning off seems to encourage the issue, so more than a little confused why a power supply might do that
 
sounds like a motherboard issue to me.
Pretty much impossible to tell without fully testing each component on another system.
Any friends that could help with that regard ?

Well soon, My sons system will be built but until then, not really.

Do you think ti could be the Sata controller?

What leads you to thinking it could be motherboard rather than PSU?

Silly question but is there BIOS setting that could be causing this Sleep state issue?
 
PSU could have cause the fault originally, but it sounds like it has fried something on your mobo.

I presume you are now running the rig with your backup PSU and its still happening ? based on that assumption I would say it was your mobo.
If that is not the case then you need to run on the old PSU to be sure.

does the mobo have onboard VGA ?
does it still do it when the gfx card is removed ?

TBH, with the hardware you have an me advising this over the internet, bear in mind whatever I say will be best guess.
Without methodically testing/replacing components there is no way you can be 100% sure what is wrong.
If we had this system in my shop we would be testing each component one by one in another system, and also testing known working components in your system. I have seen some weird issues in the past, where a gfx card will not work in a customer's pc but works just fine in ours, but an alternative gfx card works just fine in both.

Thanks for your insight, unfortunately no onboard graphics. Psu retailer has offered testing and RMA so may just have to suck it up an pay the penalty if its all ok, I don't have correct testing equipment to know for certain.

But surely if something was fried, it would be a permanent non changing issue?

Just edit to answer your other question I am still using original PSU and system is working ok at the moment.

no things don't necessarily get permanently fried. Which makes fault finding a royal PITA
