My MSI 6800 GT don't pass dxdiag tests

Hello all,

Installing properly my new MSI 6800 GT artifacts appears on the desktop containing green(mostly)& red points disappearing when raising Color Quality to 32 Bits. Directx cube freezes in DirectDraw & Direct3d tests. All programs runs fine except 3d games. A clean install of OS and/or MSI & NVIDIA whql drivers don't fix the issue. I reserve an exclusive 12V line(@36A)for VC power connector, proving all of 4 molex. I put my MSI 6800 GT $ PSU on my old P3-800 256MB Rambus and Directx tests pass. I put my old Creative TNT2 32MB on my new PC's AGP slot, passing all tests. My new system(see signature) pass memtest86, SuperPi & prime95. Not overclocking either CPU or GPU and all Temps and Voltages are normal except a very little high 12.58-12.70V in +12V rail. Official MSI VC BIOS.

When I got this VC it worked fine. Then I auto-overclocked to 410/1110MHz. At some time (I didn't know when) my VC failed.

Thank you so much for your help and attention.
