Odd FPS drop in game

[Morept4u]

Hey guys.

I have a:
i5-4690k
16Gb Ram
GTX970 video card

When I play GTA5 my FPS drops down to 10-15 fps. I then exit the game and update the driver using Gforce experience. After the update my FPS in game jumps up to 60 FPS. I then turn off the game and the computer. I boot up the next day and in game my FPS is back down to 10 - 15 FPS. I have changed no settings. I open up Gforce experience and there was another driver update. I update and my FPS jumps back up to 60 FPS. I repeat the same thing the following day but my fps is back down to 10- 15. I look for yet another driver update but Gforce experience says my drivers are up to date.

I tried exiting all other background programs to no effect.
I ran Gforce experience again to look for another driver update. It says I'm up to date.
I opened up device manager and looked at the video card for conflicts. No conflicts.
I'm at a loss here.

Does it happen to other games too?

Possibility 1: Overheating. Do you have MSI Burner, or similar software that controls your GPU fan speed?
Possibility 2: Issues GTX 970's VRAM. The first 3.5GB is fast, while the remaining 0.5GB is slow.
Possibility 3: Try uninstalling your graphics drivers, then reboot, then download and install newest graphics drivers. Try using a tool called "DDU" to uninstall your graphics drivers.
