✔ Best Answer
Did you have the same problem with the old PSU?
Disconnect all peripherals; HDD, SSD, USB devices etc.
Does it still shutdown on boot?
Is the CPU cooler firmly attached? Have you removed it for some reason?
If you can get to the BIOS, check temps and voltages.

Why did you replace the PSU? Did you get a decent name brand unit? It sounds like it's either inadequate, you forgot to connect something, or the CPU is overheating.

Yes I removed all parts off motherboard and heat sink. The pushpins on heat sink fan assembly 2 won't grab also did not reapply any thermal interface material so could be over heating? The Pentium 4 LGA 775 came with this fan purchased it like 12 years ago just trying to get something working for the grand kids

"could be over heating?"

Definitely, thermal protection circuitry is causing the shutdown. You'll need fresh thermal paste plus the heatsink must be firmly attached. Use the middle dot method: http://www.arcticsilver.com/pdf/app...
