System specs first:

6500k i5 3.5GHz
MSI 980ti 6G Gaming
MSI M5 mobo
GSkill Ripjaws V series 8GBx2 DDR4-2400
Samsung Evo 850 500GB SSD (primary)
EVGA 850 80+ Gold psu
Fractal define R5 case
Win 10
One 1080p 144Hz monitor

Issue I'm having is that games that used to run at 144fps seem to be struggling to hit 40fps now. I've deleted the old nvidia drivers, and installed the latest, thinking it was a driver issue. I've pulled off v-synch from the nvidia control panel, and I've changed settings in-game to see if that'd help. First noticed it after installing Doom, now load times are increased, and capped at maybe 54FPS. KSP started having loading issues where it'd get to "loading asset bundle definitions" and hang up. Finally load a game, and met with massive FPS drops. I play minecraft for my kid (not quite old enough to do it himself), and that went from 144 cap consistent, to flatline ~38 FPS. Short of uninstalling games and trying fresh loads, I'm not sure of what to do.

Ran 3DMark Time Spy benchmark, and ranked below an i5-4580 with a GTX970.
Also ran malware and virus check, just in case, and both came back clear. Rebooted PC, and noticed longer load time on OS and any game I try and open.

Any suggestions are greatly appreciated.
 
Solution
Check your CPU and GPU temperatures while gaming. Also try uninstalling Geforce Experience. Anything unusual showing under the performance tab in task manager?

Already uninstalled GFE. Temps are good on both 42C on CPU, 50C on GPU under load. Nothing unusual showing in task manager. One thing I did notice; everything is taking much longer than usual to load. I've got most of my games on the SSD, as well as my OS. OS loading a good 10 seconds slower, and games are 30 seconds (or more) longer to load. I'm wondering if it's not an issue on the SSD. Possibly wipe it and start again. Thoughts?

**UPDATE** Looks like something's going on with either the mobo or the CPU. BIOS screen is showing CPU is running at 0.80GHz....

I'll try the benchmarks and see if there's something there. Haven't updated the mobo in a while, so I'll try that as well. I'll post later once I've had a chance to try that. Thanks for the help!

It kind of happened all at once. I'd normally agree that disc space is the main issue (I'm almost at capacity, with 40GB remaining), but I noticed it maybe a week or two AFTER I had installed/been playing Doom. I was getting 144FPS on that, and then overnight I started getting slow loads and capped at ~50FPS.

Turns out the CPU was running at 0.80GHz. It was a setting that had somehow been enabled in BIOS. (seems like a somewhat common MSI mobo issue. If you happen to have a Z170A board, it's BIOS>Overclocking>CPU Features>Intel Adaptive Thermal Monitor>Disable)
