Question Did hard reset fry my asus board

[rostopchin]

I just upgraded from an Asus p8p67 / 2600k to a ryzen system, but had to rma my new motherboard and cpu due to incorrect memory being fitted (couldn't swap it myself as it was a hardware bundle with warranty so needed retesting with new ram). After sending the new mb back I put the old Asus back in my case to use temporarily, and hooked up an ssd with the old Windows partition on it, but it wouldnt boot into windows.

I couldn't get it into safe mode to see what was wrong, as I'd never set up f8 boot options, but then I read that if you do a hard reset several times straight after powering up the system, windows would go into diagnostic mode.

So I did this, but then found the system wouldn't post at all. The dram light flashes briefly but then goes off, the green standby led is on solidly, the fans spin and the USB peripherals power up, but nothing comes up on the screen. I've reset cmos several times, swapped gpu slot, tried a new gpu, removed and replaced ram sticks. I don't know how switching on and off could kill the system? The only thing I don't have is a case speaker so I don't know if I'm getting a beep code. Any suggestions? I'd like to get it working as I planned to sell it once my new system is returned...

Update your post to include the full (old ASUS system ) hardware specs.

Especially PSU: make, model, wattage, age, condition?

Could be a PSU failure.

Yeah I think the reason Windows wouldn't get beyond the loading screen was due to the ssds being plugged into different ports (couldn't remember how I'd had them set up). But would that stop it posting? after all it had been starting up OK before the hard resets? The PSU is a superflower golden fanless, it's expensive and supposedly very good quality so I hope it's not that...
