About the 9T of drive space, I have a 1T C: drive and four 2T additional drives. I make my backups to some 2T drives that I can hot-swap through a SATA dock on the top of my case, a Thermaltake Chaser MK-I tower. I used to back up to DVDs, but found that no matter what the brand of media or brand of burner, discs written at 8X or faster were unreadable with time, and writing at 4X just took way too long. I used to backup to Blu-ray, but as hard drives came down in price, backing up to disc became the more reliable, faster, and cheaper process, and no more being linked to the computer to swap media for hours.
Thanks for the link to the latest XML 4.0 download. I'm going to install it tonight (more on that later).
I tried playing with the monitors - swapped them around, swapped in another monitor, enabled the on MB video and connected up a 32" TV to it, but no improvement.
However, I now have it working!
As I'm always frustrated by posts where there are no details on what the person did to fix the problem, I'm going to describe what I did.
Powering down and wiggling cables and wiggling the video card accomplished nothing.
I replaced the "C:" drive with a clone I had made back in May (I routinely "clone" the "C:" drive in case it fails or becomes corrupt - something I learned while working at AOL a decade ago). Unfortunately, the problem presisted with the clone, so I put the original "C:" drive back in.
I borrowed a diagnostic disc from a friend and ran it. The disc is a proprietary disc his company created and runs several utilities under control of a script. I had to enable the onboard video and connect a monitor to it as it by default didn't output to the video card. The diagnostics take about 90 minutes to run, but I didn't know that, so I spent a lot of time waiting for them to finish.
The diagnostics were showing a video problem with a screen full of "FAILED!" messages. Driver problems, Direct-X problems, a real mess.
I completely uninstalled the drivers and Catalyst software for the 3rd time. I rebooted twice, just to make sure there was a clean boot. Still no luck. Ran the diagnostic disc again. Same problems.
I powered down the system and physically removed the video card from the MB, then re-inserted it, reconnected the power, etc.
I ran the diagnostic disc again (waited another 90 minutes while it ran). Many fewer problems!
I completely uninstalled the video driver and Catalyst software for the 4th time.
This time an odd thing happened. Windows 7 Ultimate decided that it wasn't happy with there being no driver for the HD6870, so it installed a very, very, very old version of the driver. It did not install the Catalyst software, so while a very old driver was installed, there were no utilities and the old driver decided to "scale" the monitor output so that there was about a half inch black margin around the content.
I installed the latest drivers and Catalyst again, disabled the scaling (so that the video output would fill the monitor). All appeared well.
Rebooted twice. Looks good!
I ran the diagnostic disc, and it came up clean! Everything passed!
I crossed my fingers and ran Roxio. Success! The menu utility was running properly!
I ran all sorts of software - video editing, photo editing, video capture, Blu-ray player, DishAnywhere, etc., and everything ran correctly!
So, I'm chalking this up to a bad connection between the video card and the MB, which shouldn't happen with gold contacts, but apparently did. And dust isn't a factor as the inside of the case (a Thermaltake Chaser MK-I with lots of filters, the cleanest case I've ever had).
I'm now heading off to the local computer store to buy another drive. I'm going to clone the "C:" drive again and start rotating through two clones instead of having just the one clone. BTW, I use Acronis to perform the cloning operation. I've used various versions for years, and have been very happy with it. I used to use software that came with a new drive to make clones, but at work they used Acronis, so I switched to it for home use.
After I've made the clone I'm going to download and install the XML 4.0 and install it. I'll run it a few days, and probably make a new clone next weekend - one which includes the XML update.
Thanks for all the responses! I appreciate the help!
