GPU Graphics Card Problem: Memory at 0 MHz

Solved
frenesystyk -  
Hello,
I'm reaching out to you in despair; great forum, but I couldn't find a solution...

I have a problem with my 8800 GTS 640 MB Twintek graphics card. I overclocked it and played for a year and a half without any issues (Crysis, Stalker, Far Cry 2...)
For the past few months, I've been experiencing the following problem:
When I launch GPU-Z, on the frequency line it shows GPU Clock => 0 MHz, Memory => 0 MHz, and the Shader box is empty and grayed out... but the graphics card still works albeit with reduced performance...
I've tried other versions of GPU-Z, and it's the same, as well as the graphics drivers.

So, if someone can help me?
Configuration: Asus P5k Deluxe Q6600 @ 2.7 GHz 4 GB RAM Geforce 8800 GTS 640 MB Windows Vista Firefox 3.0.5

    Thanks, but with PC Wizard I can see that I don't have the right frequencies....
    I'm going to order a GPU
    Thanks, see you later

      otherwise you can download Everest 5.0 for more info on the GPU, check in monitor and then GPU

      otherwise I think that if all the drivers are properly installed you should have multiple temps for the GPU, CPU, RAM, PCB, VDDC, etc.

        Did you install the various components of the motherboard?

        Otherwise, it is possible that the PCI-E port is not recognized, then it does not recognize the graphics card.

          So I don't know if the 8800GTX is like my GTX260 or the big GTX ones, but it runs at several speeds. My GTX260's speeds are:

          300MHz 100RAM 600Shader at rest
          400MHz 300RAM 800Shader under 2D load
          640MHz 1150RAM 1450Shader under 3D load

          720MHz 1250RAM 1500Shader overclocked

          Have you tried GPU-0.3.3?

          You need to uninstall all the various NVIDIA display drivers and reinstall them.

            Thank you, but as I said, the graphics driver is installed and it's still at zero; normally the default frequency is 513 MHz
            I just saw that with the PC Wizard software it shows me a frequency of 198 MHz for the GPU......
            ???
            Is this a hardware problem?

              If it were at 0 MHz, there would be no display,

              it is at 0 MHz according to GPU-Z because it is not recognized by the software, no graphic drivers
              install the drivers and it will be recognized; for the moment, it runs at its default speed of around 300 or 400 MHz
