Another potential is the CPU.  Assuming all the hardware you changed is 'known good' items.

I had to 'shotgun' troubleshoot a problem on one of my desktops, too.  None of the available diagnostics detected any problems but it kept randomly crashing with blue screen.   As I do PC repair I had spare parts.  Started swapping, one at a time until I found the problem device (CPU).

I had a similar situation, but I ran into an undocumented cause of an amber blink. RAM.

In my case, if I had mismatched pairs of RAM modules (one pair dual ranked and the other pair single ranked - which according to Dell is okay), I would get a blinking amber LED.

You didn't mention replacing the ram.
