Right. Finally got some things sorted. My graphics card is causing system crashes, and is getting sent back on Friday or Monday. Cruising the internet, countless other people have had the same problems I have had with the nVidia 5-series graphics cards, across multiple platforms, which means it isn't a simple compatibility issue.
Unfortunately, I'm getting another GTX560 in return - assuming they agree that my existing card is faulty - after which point, it'll either work, or I'm going to pick up an ATI Radeon 6850.
The one thing that is bothering me is this:
Speaking to a few folk, there isn't any conceivable way my computer could actually run with such a low 12V rail voltage, but...what do you think?
This was one of the graphics drivers issues, which many people seem to suffer. i've tried three different iterations of drivers (Beta drivers, these drivers, and the version before)
and this was one report from my endless succession of BSOD showing nVidia drivers were still causing crashes. I've had other sorts of crashes besides BSOD's, though.
Any suggestions about the 12V issue, and does anyone agree that sending the card back is a reasonable course of action?
It's worth adding that the BIOS says that 12V rail is at 11.538V. I'm inclined to trust the BIOS over the CPU monitor program...
