My Problem:
Constant freezing. No mouse, keyboard, or anything function. Requires hard re-boot.

Causes:
Unknown specifically, however I can force a freeze with WoW even on lowest settings and the Vista Rate your PC thing.

Side Notes:

I built this rig last september. It ran great for about 8-9 months. Thats when it started freezing more and more often. The last straw was recently when I could not even log into WoW (set on lowest settings) without rebooting.....meaning I got to the log in screen, punch in my password and bam....like a bad episode of Reno 911......"Everybody Freeze" 

Things I have done already:
Ensured all drivers are up to date.
Removed all but one stick of 2 gigs ram and rotated them all through with no difference in general perfomance.
Contacted Vista Tech Support....;( Not much help but hey, whatever.
Vista TS lead to CHECK DISK (forever) and new install of Vista.
Which lead to their conclusion that my GPU was going bad.
My Previous GPU was an EVGA 9600 GT, so I purchased the above MSI GPU as a fix to my problem that Vista TS evidently was wrong about. Installed and works like a champ only I still can not complete the Vista rate your pc thing without it freezing.
I have yet to re-install WoW to see if that still causes it also as I am at work till Monday.

Other thoughts:
I built my own PC so that might be my problem. Though I would considder myself somewhat tech savy I know i'm kidding myself when talking to the likes of you all
However, I have a friend at work that has built several PC's and helped me at every step of this build from research to super glue on my "finned" finger tips. (thanks Zalman) Only he is dealing with major chick drama and I need assistance before I see if a size 11 Danner fixes my PC.

Please Help if you can.....

Well the PSU can cause this however so can many other things like overheating, RAM or video card even the HDD going bad. But even though you ran a chkdsk /f does not mean that its not failing run SMART on the HDD and see what happens. Check all the temps GPU, CPU, ect...

Easiest way is borrow a 500W PSU to test your rig with.

Well, looking at your problems, I'd say it's quite likely that it's your power supply.  Plus, RaidMax power supplies are well known to be terrible.  They're in the worst tier on the Eggxpert Tiered Power Supply List.  Here's a nice video showing the "quality" of Raidmax power supplies.  And yes, all of those power supplies shown in that video are RaidMax units. 

As a rough estimate, I'd say that your computer probably draws around 400-500watts at max load, so, you could test it out on a good-quality 500watt PSU, as GMSCool recommended.  However, for long term usage, you'd probably be better off with a 600watt power supply. 

Right now newegg has the OCZ StealthXStream 700watt power supply on sale for $47.49(after $20 rebate).  That's a solid power supply with plenty of power for your computer.  Those OCZ units have been on sale cheaper before, I bought a 600watt StealthXStream unit almost a year ago from newegg for $20, and a 500watt unit for $15.  Unfortunately, those sales haven't really been common since then.
