The problem:

Hi! This is a new PC I just built. Everything has gone well except some
minor issues that may be major. The PC keeps turning off without warning
when I view video files, installing games/software from CD/DVD, and whenever
I scan the registry for cleanup. But the PC can run for hours without
problems if surfing the web, writing word documents, or keeping the PC idle.
Can anyone tell me what the problem is? Thanks!

Go to this website.. enter your system hardware configuration as required..
compare the result with the power supply fitted.. you may also have a heat
problem, and may well have to employ water cooling in your system case..

According to the site you gave me, I need about 235 watts of power. My power
supply is a 430W and is made to be compatible with the LGA 775 processor. I
have never heard of water cooling in a system case. Thanks for the
suggestion. I could use more suggestions and opinions. Anyone else have any
suggestions?

Mine requires more than yours and is less well specified in part.. you might
want to look at the heat issue then..
