The Nvidia card with the melted fan was original hardware that I replaced with the Best Buy Nvidia card. It doesn't support Vista but as you said, it's more dated than even its predecessor, XP. The MB surprisingly is made by AsusTek and branded as HP's Basswood3G. HP also dumped Vista and all of their driver downloads along with it. I mentioned earlier that the MB doesn't have onboard graphics and the generic VGA driver shows a Code 10 error in Device Manager saying it can't start. The video and graphics are spotty with wild artifacts but how's it able to generate any at all? Where is it coming from? The driver issue and spotty graphics showed up a couple of weeks ago and I'm guessing a Windows update changed something. How that may have come about is when I checked Windows Update logs to see why it wasn't finding any updates. The logs were showing "The system has been restored. Hence triggering AU detection through DetectNow API. Triggering AU detection through DetectNow API..." which seemed at odds with my "let me decide" settings given its next message line, "Can not perform non-interactive scan if AU is interactive-only." After that, it ran static reporting data, then ended with no updates. And that's when I changed the update settings to run fully auto and possibly, allowed a change that effected the graphics driver. But it started downloading updates and occasionally, successfully installs one or two but more often fails with "...Servicing failed to complete the process of setting [update package] into installed state" or "install requested state" or "into uninstall requested state" or "failed to complete process of changing update from [package] into staged state" or "into absent state". Windows Update sets a restore point and every few seconds after that, Trusted Installer sets another one up to a dozen times and will do this a couple of times a day. So my system is doing what seems graphically impossible and isn't doing what seems ordinary. On the other hand, Vista seems the most disfavored OS on the planet so what should I expect, right?
