Need help from the gurus

Ok, I just got some new parts today and threw them in and now having problems. Here's the story.

System was running perfectly find earlier today.

Stats:
Asus A7N8X
AMD 2.2 GHZ
512 RAM
Radeon 9800 Pro 256

Those are the vitals...

Today I moved everything into a new case and added another 1 GB of RAM, a new heatsync and installed a new 500 watt power supply.

Now I boot up the system, it stays on for about 5 seconds and instantly shuts down. Any ideas?

try reseating the heatsink, the vid card and use 1 stick of ram at a time.

oohhh, if ur unlucky, u may have fried ur core. reseat heatsink is number one. then exchange each part with a spare to find the culprit. start with stuff that u can easily change. did u knock any capicitors around during the change? finally and most easliy, reset the bios.
