Recently I upgraded my video card to the new EVGA Geforce GTX 960. After reading multiple threads and articles I saw PCI-E 3.0 is backwards compatible. I previously had an EVGA Geforce GTX 9800+ PCI-E 2.0. Once I installed the new card the system does receive video but when it gets to the point where it would boot into windows the machine just restarts. I put the old video card back in, the system boots fine. This is a computer I built back in 2009 and upgraded every so often through the years. The following is the specs for my machine:

EVGA E758-TR 3-Way SLI (x16/x16/x8) LGA 1366 Intel X58 ATX Intel Motherboard
9GB Corsair XMS DDR3 1600 (PC3 12800)
Intel I7-920 Bloomfield 2.66GHZ Quad-Core
Thermaltake Blackwidow TR2 RX 850 Watt Power Supply

I am currently running windows 7. I have considered flashing the BIOS but I would rather exhaust all other options before doing this.

Any suggestions would be greatly appreciated.

You need to uninstall the video drivers for your old card and install the video drivers for your new card. Boot with the old card, uninstall drivers, it will revert to Windows default VGA driver. Shut down the computer and put in the new card. Start computer, then install the drivers for your new card.

I removed the nvidia graphics from the control panel, but I will try from the device manager as well. Thanks for the advice, i'll let you know how it works. At work right now so I'll have to try in the morning.
