Random Lag spikes, Blue Screen after installing EVGA GTX 970

Hi all,

Yesterday I installed an EVGA GTX 970 (the 2974) in my system. I uninstalled the old drivers, updated the firmware for the ACX 2.0, and then installed the new NVIDIA drivers. After installing the new GPU, though, I noticed that my computer now has random massive spikes of input lag where the keyboard won't type characters and then spits out a dozen or so and the mouse jumps across the screen. It happens both when I'm just surfing the web (as I'm typing this, my mouse is acting very jumpy) and sometimes when I am in game. The only thing I changed in my computer was the GPU; could it be a bad card? I also notice coil whine like many others have with the 970s; is that an issue?

What do you guys think would be causing this?

my specs:
Mainboard : ASUSTeK COMPUTER INC. P8Z77-V LK
Processor : Intel Core i5 2500K @ 3300MHz
RAM : 16384 MB DDR3-SDRAM
Video Card : NVIDIA GeForce GTX 970
Hard Disk : KINGSTON SNV425S2128GB (128GB)
Hard Disk : Samsung SSD 840 PRO Seri (128GB)
Hard Disk : Seagate ST1000DM003-9YN162 (1000GB)
Network Card : Realtek Semiconductor RTL8168/8111 PCIe Gigabit Ethernet Adapter
Operating System : Windows 7 Home Premium (64-bit)
DirectX : Version 11.00

EDIT: I just reran the Windows Experience Index tool, since my score was out of date and my graphics score dropped from a 7.8 with a GTX 560 Ti to a 6.0 with my new GTX 970!

EDIT 2: Just got a blue screen, stop code 124. The crash dump is below:
