Hello. 3 weeks ago, I built my first gaming PC. I downloaded 3 games.
Minecraft
TABS
Gone Home
They were running flawlessly. But, about a week ago, I started to get lag in them. I usually get 500 fps in Minecraft, now I only have 4-30 fps. TABS and Gone Home are also running slowly to the point it's unplayable. It's getting really annoying.

Specs:

CPU: Intel Core i5-6600K 3.5GHz Quad-Core Processor
CPU Cooler: Corsair H100i GTX 70.7 CFM Liquid CPU Cooler
Motherboard: MSI Z170A GAMING M5 ATX LGA1151 Motherboard
Memory: G.Skill TridentZ Series 16GB (2 x 8GB) DDR4-3200 Memory
Storage: Samsung 850 EVO-Series 250GB 2.5" Solid State Drive
Storage: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: MSI GeForce GTX 1060 6GB 6GB GAMING X Video Card
Case: NZXT S340 (Black/Red) ATX Mid Tower Case
Power Supply: EVGA 600B 600W 80+ Bronze Certified ATX Power Supply

Something is causing you issues. It could be a number of things:

First, did you install anything (driver/software/hardware) around the time the issue started to happen?

Otherwise....
* Overheating - system (CPU and/or GPU) is running too hot and throttling
* Virus/maleware - something may be tying up system resources (CPU and/or RAM)
* Faulty RAM - usually faulty RAM is meet with BSOD, failure to boot, but I have see a couple of instances where a stick of RAM was bad, but the system still would boot, but it ran like crap - everything was slow.
* I've seen Windows 10 updates cause issues before. You could try uninstalling the GPU driver (use DDU) and then re-install it. See if that fixes anything.

I noticed weird problems when I overclocked my 6700k. Even though stress tests and various benchmarks indicated the CPU was stable, games acted strangely. Like mouse movement freezing the game until the mouse stopped. If you overclocked your 6600k disable that and see if the problem goes away.

I would check all the numbers and make sure windows is registering properly, CPU model ghz., ram speed and amount, harddrive has available space.

After that I would check all the hardware plugs, power, sata plugs, swap ram slots, perhaps even try running on one (sometimes you cant).

Last resort I would reseat the cpu, and last last resort I would reinstall the OS. Good luck

I downloaded HWMonitor, and I can see the CPU overheating. Then, I saw my 2nd CPU fan not turning and i left it like that because the pin is too far away from the fan.
