I just replaced my GTX 960 with a GTX 980 Ti that I got from a friend. It does work but odd things are happening so I decided to poke around in the BIOS and I noticed that it is detecting as a X16 card but looks like it is running at X4 (See attached pic). In a couple of games I've noticed that if I run the graphics high that it will either reboot the computer or run extremely laggy. And many times it will not even boot unless I turn off the power switch on the power supply and turn it back on. Any ideas would be appreciated.
Sorry about that...wrote it in a hurry this morning. The motherboard is:

Your newegg link is not working. Here is the Intel link on your board:

There are likely compatibility problems with the GTX 980 Ti card. The boards supports PCIe x16 2.0, while the cards are PCIe x16 3.0. They may claim backward compatibility, but this compatibility is often hit or miss.
Are both cards from the same manufacturer?
While I do not believe this to be the case, have you updated the bios of the board?

I'll check the brands tonight...I don't think they are the same brand. One thing I read on-line was that it might be related to UEFI so I enabled that on my board this morning. When I did that the X4 changed to X1 so I'm thinking that isn't the speed it is running at but something else. Anyway after I made that change the system seems to shut down and boot more consistently but still a bit buggy. An improvement either way. I just did that quickly this morning before going to work so I haven't had time to test it yet. I'll do some gaming tonight and see if it is any better.
Well the computer is running much better after enabling the UEFI. It no longer reboots or lags badly when set on the highest game settings. The only issue now is I still have to flip the power supply off then on again to start the computer.
Hello Al Hill, thank you for your contribution.
To InspGadgt: good to know the system is running better.
