i7 4790k, 8GB of RAM, and a Nvidia 970 GPU - yet my PC still feels slow and sluggish?

Within the last couple of months, I changed my computer's CPU from an AMD FX6300 to an Intel i7 4790k. I wanted my CPU to be parallel with my GPU, a GTX 970, so I could get the most out of games and applications with no bottlenecking.

During my time with my AMD processor, my PC had consistent and annoying issues. Whilst it played most high-end games perfectly on ultra/very high settings, basic stuff such as searching through my files, using applications such as After Effects, and even doing basic things such as using Chrome to browse the internet led to freezing, stuttering, and such applications shutting down after failing to respond. Even trying to look through my documents or videos would often cause file explorer to crash.

Initially I blamed my mid-range, aging AMD processor. I thought buying an i7 4790k (and accompanying motherboard) would give me the performance and stability I needed to use my setup as both an effective editing and gaming machine. Whilst many games do seem to run slightly better, the previously mentioned issues persisted. I was slightly annoyed that the expense I paid for the new CPU had not solved the problem, but it had highlighted the fact that the CPU was perhaps not to blame for the annoying and basic performance issues.

As a very amateur PC builder, I extend this dilemma to the resident experts of Tomshardware. Perhaps my odd issues are to do with my operating system? Maybe the speeds of my Hardrive? I would be very grateful if any kind and knowledgeable user would advise and help me on what may be causing the issues and how i may go about fixing it. Thank you for reading this, and a thank you in advance if you know how to help.

My full specs;
Operating system: Windows 10 Home (64 bit)
CPU: Intel Core i7 4790k
RAM: 8GB DDR3 (dual channel)
GPU: Nvidia GeForce GTX 970
HDD: 2TB Seagate Barracuda
PSU: 550W

It sometimes takes a while to startup, internet loading times are slow and not reflective of my internet speeds (avg. 5 - 6MB/s), the most basic of apps tend to freeze, become unresponsive for a short while, or even crash completely - this includes things like the file explorer, with it happening most often when i search for files. Less common than the crashes my computer will freeze entirely. Audio can be heard from things like videos that continue to play whilst this happens, but any open apps, games, even the toolbar, become completely unresponsive. This can last anywhere between 10 - 30 seconds, before the PC seems to catch up with itself and normality is resumed. Its just the seemingly very basic computing tasks that seem to somehow cause issues with my system. Despite my recent upgrade, things don't tend to feel any quicker - any idea what it could be?

You may be experiencing thermal throttling. Check your temps while using your programs. There's also a chance you may have messed something up while installing your new processor. Did you try to reinstall Windows? Reinstall all your drivers also.

16GB of RAM
An SSD 128-256GB
Which will give your 4790K some running room.
A real shutdown is unplug power and battery.
A reinstall of windows and the drivers for your 970 on a usb key.
If you have a number of helper apps install them one at a time.
Try one game at a time.
Look to the EUFI bios for XMP settings and set performance for games on.

When in low usage, ie when i'm not playing games or using other intensive apps, my temps rarely exceed 30ºC (86ºF). They do shoot up quite a bit when plying games however, with my CPU usually hitting around 40ºC (104ºF) and my GPU usually hitting anywhere between 50ºC to 60ºC (122ºF to 140ºF). I understand these are high temps, but it is only prevalent when playing games - which my PC does with no trouble. Regardless of the temperatures I am still met with the same previously mentioned issues.

As for windows, when I changed my motherboard over my copy of Windows 10 appeared as non-genuine. After I couldn't retrieve the correct product code for my OS using a program I'd installed, I contacted Microsoft who solved the issue for me. My Windows OS is genuine again. If I have done something to my OS when I installed my new hardware, surely the problems I'm dealing with would only appear now. The aforementioned issues were still there when I was using my original AMD processor and AM3+ motherboard.

How would I go about reinstalling my Windows 10 OS and the drivers for my 970 using a USB? Also, the SSD and the RAM sound like a good idea. I've been meaning to get an SSD and install my operating system on to it for some time now - do you think this would solve, or at least lessen, my issues?
