BSOD after run time

It seems like a bad slot, here's a quick test for you to try, place one RAM stick in the slot which seems to be bad, and then try and boot the computer.

Memtest86+ has no memory limitations at all.

Okay, so it's not booting in Slot 1, and it fairly clear you don't have bad RAM sticks but most likely a bad DIMM slot.

hummmmm i have a other problem when i active sli the driver crash i think (driver crash/bssod) no ?

Do you get any problems with SLI disabled?

Okay, we're back with the nVidia graphics card driver, which leading me to three possibilities: graphics card driver, graphics card or a faulty PCI/PCIe slot on the motherboard.

Firstly, remove the driver completely from your system, and allow the generic Windows VGA driver to install itself, by following these instructions. Stay with the VGA driver for a few days, and report any crashes.

1. Start Type: Device Manager
2. Expand Display Adapters
3. Right-Click Driver Name, Uninstall
4. Reboot
5. Run Driver Sweeper
6. Reboot

Driver Sweeper will scan for any left over files from the old driver, old driver files can cause conflicts with new driver installations. Create a System Restore point beforehand, in case any problems or issues arise.

Driver Sweeper:

• Drivers - Clean Left over Files after Uninstalling

The exception which has happened in the kernel, is a Double Fault, the processor was handling a exception caused the the nVidia graphics card driver, but during the processing, a another exception has occurred.

If it doesn't crash within a few days with the VGA driver, then you may install the nVidia graphics card driver. Otherwise, if it does crash, then you have one of the other two possibilities.
