PC Lag, broken RAM or CPU?

[ErvinBoyes]

My PC constantly lags. Games run at 60 fps but stutter, PUBG has lag spikes making it unplayable, Chrome crashes all the time, Adobe Premiere is unusable sometimes. My temps are fine, I think (max temp with cpu is 85 when i test it but thats just the spike at the start and thats core 0, it levels off to about 70/60 degrees, but its not overclocked and I have a Dark Rock Pro 3 BK019), I've ran memtest and checked each RAM stick and nothing was wrong (I got a BSOD "PAGE FAULT IN NONPAGED AREA", but that was only once), my drivers are up to date, I've defragged my hard drive and ran the check disk thing in cmd and there was nothing. Is there anything else I could do to try and find the problem? Thanks.

Windows 8.1 64 bit
i7 4790k @ 4ghz, Dark Rock Pro 3 BK019
MSI GTX 970 4gb VRAM
2TB WD BLUE HDD containing windows
120gb Kingston SSD

Hi Ervin,

1) Can you check and switch off XMP profiles in BIOS?
2) Also check your task manager if there is another task spiking when the slowdowns occur, I normally do this on a second monitor.
3) Run a full scan with a virus checker.
4) Check if you BIOS is running the SSD in IDE instead of AHCI.

hope this helps,
Gabor

Oh yeah, I forgot to say, the task manager doesn't seem to show any high usage, unless I'm on a game or Premiere, but its never 100% RAM or CPU usage. I've ran my virus checkers and it didn't detect anything. I'll try the other 2 things now, thank you

So the XMP Profile was disabled, but I have no idea how to check if my ssd is running in Ide or ahci. Surely this doesn't matter if its nor what I use to boot though right? If it still does, should I try and see what my PC is like without it? It only has games on it so I'm not sure if its worth it

MERGED QUESTION
Question from ErvinBoyes : "Constant Crashes and Lag"

Recently I've started to become concerned with constant lag spikes and crashes. I first noticed it when Player Unknown Battlegrounds just stopped working a couple months back: when I start a game, the furthest I can get is jumping out of the plane, and then it just crashes. I get slight stuttering in most games actually, such as small games like garry's mod as well as more demanding games. Even everyday software lags, Chrome being the worst. It just straight up crashes for like a minute when I switch tabs sometimes. I've even tried switching browsers which didn't work. Adobe Illustrator and Photoshop also occasionally act up too, and I don't do anything ridiculously demanding, especially for my computer. Adobe Premiere is the worst though, when I use the media browser it just crashes my whole PC, but when that happens its using most of my CPU, where as in the other instances that's not the case. However it lags when I'm editing 1080p video. Even if I'm at like 8% CPU and 40% RAM usage my PC still lags. I've ran malwarebytes and nothing was wrong. Spotify is also quite laggy but I've always had that even on my phone. I get like 40 degrees at idle with my GPU, my CPU gets 84 degrees max at 100% usage, but its not overclocked, and I have a Be Quiet BK019 Dark Rock Pro 3, so its a little concerning. I bought the cooler because of past cooling issues, and yes, I know, I need to overclock my CPU, but I want to fix my PC first. I've made sure twice that it was installed correctly. That being said it only spikes at 84 degrees at the start of the test, and thats only core 0, the rest are much lower. I did get a random BSOD a couple of weeks back: "PAGE_FAULT_IN_NONPAGED_AREA". That being said its only happened then and no other time. I did run a memtest after this happened and it seemed there were no errors, although I didn't run it for ages, only an hour or so. All my drivers are up to date. I should also point out that I have a 21:9 monitor which perhaps could cause problems in games, but even still it shouldn't cause problems in everyday software. Furthermore, apps that I pretty much always have on are Discord, Spotify and Steam. Any help is much appreciated. Thanks.
