Venus 5 3D deck error

Hi,
I have been constantly getting the error shown:

3D error

I have reinstalled Direct X 9c and scheduled a nighty restart but I Still get this error all the time. Today it has happened at 10:30 and then again at 12:10.
Due to my permission level on the software, every time it happens I have to get someone else to switch the deck view back to 3D for me.

Does anybody know of a long term solution to this issue? or would a new PC/graphics card be the only long term solution? (The PCs currently being used were supplied by Hamilton)

Thanks,
Ewan
