Replacing the GPU in the field...

So the video glitches which I mentioned in my last thread have one upped, and started throwing up an ATI Graphics Driver error message then black screening, which is making me think that there is a much deeper problem than outdated software (I am suspecting GPU, as evidenced in the title, although I am going to upgrade first just to make sure).

So my question is - I know there are a limited number of supported graphics chipsets for the axon - the ATI HD2900 etc... Should I be in the pickle that I think I am in (finding myself with a dead GPU in the near future, or at least finding myself with a GPU that is not stable enough to count on in a show), in the middle of the ocean and needing to pick up a new one up PDQ will any manufacturers board do provided it is of the correct chipset? Is there a specific brand of boards that HES use for the axons? I would like to stay as close to genuin as possible, but would also like to know that if I jumped off the ship and went to the local computer shop and bought a card with the correct chipset that it would work...

Anyway, any assistance would be appreciated

  • I used the recovery image, so it should be fine in that respect...

    As for the improperly encoded content... It would not surprise me at all if that were the case... I suppose I will have to dig out the old disk to 'downgrade' so I can access CMA and try again.

    Thanks

    Okay, I deleted all the custom content, got through the upgrade, now instead of just sitting there and doing nothing with the blue AXON screen, after about 2 minutes - the outputs of the graphics card just disappear, the monitors loose sync etc.

    Pulled it out of the rack as well, just to check everything was seated correctly - the GC has X1900 on the back near the serial number
