PC Performance Issues?

[Cthanion]

Hey guys, so my PC has been acting really weird recently and I can't quite place what's wrong with it, it's been happening over the past 4/6 weeks I'd say? 

 

Sometimes when a programme doesn't respond it crashes the entire system, meaning I have to reboot or just stare eternally at a frozen screen, I've waited up to 30 mins after  one of these crashes to see if it'll continue but to no avail.

 

Also, during quite intense games (often Battlefield V for example) it will stutter quite heavily for like a 4 second period and then continue normally, I also had an issue in Fifa before where it just completely froze mid-game. 

I've had performance stutters before and not really thought much of them, but when a game of Hearts of Iron 4 is loading and just decides to freeze my entire system, it can get really frustrating.

I had suspected disk errors, or more I'm hoping disk errors, my current HDD is a 1TB drive that's around 5/6 years old but is showing no performance issues in any benchmarks or system tests, I'm running my windows off a relatively new 120gb SSD. I had thought maybe the HDD can't keep up with modern games, but it's just a guess and I'm likely wrong

My system specs are as follows: 

I5 6600k OC'd to 4.4 GHz (Perviously 4.7 but I turned it down to see if it would help stability)
MSI R9 370
16GB Corsair DDR4 @ 2666Mhz (I think it's rated at that speed, I'm not 100% sure)
Gigabyte GA-z170X-Gaming 3

120GB Samsung SSD

1TB HDD (Can't remember the make, think it's Toshiba)

 

Any idea's on what it could be? Just typing out this forum post now, my chrome crashed, went to a white window. I ended it in task manager before it caused a system freeze but after that Chrome was just completely unresponsive when I opened it, like couldn't type in the search bar or click any of my favourites.

check temperatures for thermal throttling, both/either CPU or GPU.

Try Running CCleaner and Malwarebytes:

First, Revert the ENTIRE OC - Remove it for Diagnosing ANYTHING, you don't want to waste hours, still not fixing it, and find it WAS the motherboard doing something weird with the OC,.. go back to defaults for Problem Testing.

Freezing in general,... I'd first re-seat the Memory and GPU, OUT and BACK INTO their Slots.
You would be surprised...

 

Doesn't sound like a driver or harddrive issue (even if it stutters),.. more a configuration issue somewhere in the bios, and how the motherboard is playing your OC vs your Memory and how it handles even mediocre tasks can ruin it..

Temperatures are fine across the board, never hit more than 50 on my CPU and never more than 70 on my GPU

 Going to give it a go, see if it'll improve anything

Never thought of actually doing this, seems alien to me to go back down to 3.5 Ghz lol, I'll give this a try now, as well as reslotting my hardware, thanks!

I've done everything so far, I've just tried it out again in Battlefield, when it got to a particuarly taxing and hectic moment the game (and subsequently the system) just entirely froze again, really unsure what it could be at this stage?

Have you overclocked your GPU? Also, what else does it freeze on? Everything? It could be that the things you are doing are quite demanding. I'm new to the community and I am still learning so if I am completely wrong, sorry!
