My system was running fine yesterday but when trying to turn it on today it just seems to continually try to power on then turn off then try powering on again etc etc.

I've tried unplugging the PSU for a minute but that changed nothing. If I had to guess at a culprit it would the PSU since it has to be at least 10 years old now.

I'm not sure what else I can to troubleshoot this except buy a new PSU and hope that sorts it.

Below is a short video of what it's doing.

Turns out its not the PSU, I had an old CPU and motherboard knocking about and thats powered up fine using the same PSU. I had tried booting my main rig without the drives, GPU, RAM etc and the problem remained so I guess that narrows it down to either a faulty motherboard or CPU.

I’ll get hold of a new CMOS battery and see if that sorts it. The hardware is about 8 years old so I guess it could be a dead battery.
 
Replaced the CMOS battery and the PC powered normally successfully but only once, every subsequent attempt results in the same power on/off cycle as before :(
 
I dont suppose anyone knows of any forum members who might be willing to try and determine if its my CPU or motherboard that's died if I sent it to them?
