Hello Colin

 

Welcome to FPCH

 

This sounds like the PSU is on it's way out, have you tried disconnecting the hdd and booting.

 

You will obviously receive a "Disk not found error" but if it stays on then it will be the hdd.

 

I'm more of a mind to suspect the psu though.

How old is the PC - may need a new CMOS battery, the battery could be sapped and not holding the BIOS setting resulting in a crash. And could explain the issue of random timings of crashes
