Problem with Sapphire 4870 1GB

Hey I just built my computer yesterday :D  ? I was hoping to play some of my older games at high settings and high fps. Well that just made me disappointed... When I start up to windows the whole screen goes all crazy. Each pixel is different colored. Lots of noise (Not the sound). It all stays like that until I launch the ATI Catalyst and it goes back to normal. Then when I play games, some of the objects flash and then the game crashes and then gives me a .NET 2.0 Framework Error. And it says Out of memory. I'm sure I have enough ram and the graphics card is 1GB. I'm sure its not underpowered since my psu is a Antec ea650. Any ideas what is happening to my dream build?

Have you tried removing the drivers and reinstalling?

Oh yea I forgot to mention that too. I've also uninstall and installed 2 times of the newest drivers from ati and sapphire. Just doesn't work...

Antec EA650 PSU
II X4 940 Clocked at 3.0 (I lowered the voltage to 1.15 because of high temps)
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Antec 300 (I leave it open because my air condition is nice and cold)

installing service pack 3 along with the the .net 2.0 update + enabling automatic updates should help your case.

Do you have any other video card to test in the system?

@ WierdMystery: First remove and replace every motherboard component, and pay close attention to every connector, gently cleaning it with pure alcohol and a coarse cloth (I use a piece of an old pair of jeans kept for this purpose). Do NOT use anything abrasive!
Remove and replace the CPU heatsink and thermal compound, making sure the CPU and heatsink are clean before assembly, it is possible a small piece of grit has got between them and is causing your temperature problems.
On booting, reset the BIOS to stock, changing BIOS settings before the system is up and stable is just asking for problems.
