...the display goes haywire and is irrecoverable.
Greetings,
I watched your video. Instead of beating your head against the wall... please start using System Restore and/or Windows back up, Macrium Reflect, etc... in order to keep from having to reinstall your OS from scratch during troubleshooting.
System Restore will have you back in business in 2 minutes. Any of the Back Up software with in 8 min.
A few questions and a few suggestions:
What type of display are you using?
How is it being connected?
Are you using any adapters?
Is the RAM on the QVL from your board?
Are you over clocking memory and CPU?
Do you have another display to test with?
If you load set up defaults (in BIOS) current system state, does the behavior continue? (Quadro removed)
Is there anything else installed or connected to the board that is not listed in your specs?
What BIOS rev are you using?
My initial though was driver incompatibility, but believe it or not, memory can also cause this type of behavior. However, since it works up until the point you change the driver, problems with memory is unlikely.
Confirm you have the latest Chipset .inf drivers installed before testing different graphics drivers. The one here will be fine:
