ram psu and settings...?

[mattandbat]

Ok here is my problem... When I installed some ram I bought things seemed fine except for the processors until when I was doing an update on the windows experience index the computer just shut off. I restarted it and again and in an even shorter time it shut down again. I decided to take out the old ram thinking that maybe the power supply wasn't enough to power everything I have. Its a 450W power supply. It still turned off. Also during the time of the wacky turn offs the processors were just about constantly at 100 percent usage. Maybe that was because they didn't have enough power to over clock? but also earlier today I was checking a 3.2 GHz processor to see if it worked and It didn't. So I thought maybe I installed my newer processor in wrong but... When I put the old ram back in by itself everything was much more stable (as you can see because I was able to write this message). My old ram uses less power then the ram I bought so it still could be the power supply. What do you think. Also the processors seem to run a little high but i remembered that when i put my processor back it asked if i wanted to go to settings and i did so maybe that put all of the settings back to default whick i could have been overclocking them before? Sorry to bother you.

Thanks.
