[QUOTE="Alan_Reliant, post: 1744267, member: 387695"] I have fantastic news. The graphics card solved the issue. I should have known better. I think as a tech that sometimes we get too close to the issue and simply can't see the wood for the trees. In the end I took the Apple resident Nvidia home to install in my own machine. Windows 7 booted to the card; post had artefacts that I chalked up to loose cables or connectors. I arrived at a 800x600 desktop (no artefacts visible), Windows complained a little but installed the new driver and requested a reboot. On reboot the progress bar appeared, then disappeared and left me with a blank screen covered green and red flecks, it waited a minute or so before a hard reset, then the whole sequence repeated. I had to really dig around to find a compatible graphics card for the Mac Pro but my 5th attempt was the charm. I noted that the first of the cards I tried (very old and low spec) did not cause the boot loop but I had no display. The 5th card did the trick, a blank screen to start but after 2 couple of minutes, to my delight, up it came. I can't thank you guys enough for your help, I was at points during this trouble shoot ready to throw the **** thing out of the window, but hey, its solved. Thanks again Alan, a very satisfied and pleased tech. [/QUOTE]
