if you bought all that hardware new trying to fix a old P4 ,you should have jsut bought a new computer ,would have been money better spent .
my opinion is the motherboard has died ,but that just anopinion from a distance ,hard to tell with out actually looking at it in person

if you have swapped out most of the peripherals, the last two components are likely to the be the power supply or motherboard.

I wasnt clear from your description whether you checked the power supply? If you have a power meter, you can check the power connections coming out from the power supply to make sure that your motherboard and componets are getting the power they need.

Aside from the power supply, if you had access to another motherboard, I would swap that out as well to see if you do have a motherboard issue.

Unfortunately, these types of issues may sometimes be more difficult to troubleshoot and you just have to check all of the parts until you find the culprit.
