My gaming rig lags every few seconds at the start of a game

[amunds]

First of all, I've read the other related posts, but none of them solves my problem.

I've built the computer myself, and with a few upgrades now and then. Been running smoothly since 2013 or something.

The other day, it suddenly started to lag for a few seconds in the start of a game.
Sometimes it stops, and it seems like the game is running fine, but other times it re-occurs while I'm playing. This goes for all games. I'm running Windows on a ssd, and BF4 on that disc as well. Running steamgames from an older hdd, but all games are acting the same.

This is what I've done:
1. Tried reinstalling most of the drivers (perhaps not every single of alle the MB controllers, old MB)
2. Tried 3 different Graphic cards, so pretty safe to say that isnt the problem. (Tried 970, 780 and 1070).
3. Tested all my Ram chips. Got 4 x 4 in the computer, and actually one of them was bad, so is just running 2 x 4 (8 gb) right now.
4. Re-installed (clean install) Windows 10 and installed all drivers from scratch.
5. Tried to watch both resource monitor and windows event log, but nothing I could identify as errors.

It actually disappeared when I changed from 970 to 780. But came back again before I switched to 1070.

QUESTION: Could this be a hard drive (OS on Samsung EVO) or PSU-related ? And how do I best check this ?

My specs:
ASUS P8P67 PRO (rev.3.1) with BIOS 3602
Corsair CX 750M PSU
Intel 2500K CPU
ASUS nROG Strix nVidia 1070 GPU
Corsair H80i Hydro series cooler
Corsair XMS3 DDR3 1600mhz Ram (2 x 4gb at the moment)
1 x Samsung 840 EVO SSD 240 gb (OS and BF4)
1 x 1TB disc from Seagate/WD or something.

I could add that I have tried to uninstall all nVidia drivers (Experience, 3D Vision, HD Audio) except the geforce and physx drivers.

install hw monitor check your temps, heat could be throttling the system...

I have monitored the temps.. Both CPU and GPU is no problem.. What is normal temperatur for "the rest" ?

The rest won't cause a problem, try your gpu in a different machine see if it works fine. Your going to have try and eliminate different things...

Like stated in the first post, I have tried 3 different graphic cards and there is no difference. So I guess it is not the GPU in itself. Also runned all my memory sticks, and that did not show anything.

So I wonder if perhaps my PSU or perhaps the hard drive ?

You said you didn't have the problem with the gtx 780 only newer cards could be a compatibility problem with newer architecture have you tried the motherboard website for compatibility.... it's a long shot but other than changing 1 piece of hardware at a time there's not much more you can do

Yes, it disappeared right away, but came back before I switched. I had a couple of days now as well where it hasn't occured.
These first days with 1070 it occured, but suddenly the last couple of days it hasn't occured.

Tried to analyze the changes I made between the day it occured and the day it stopped occuring, but don't think I made any changes to anything at that moment.

This kind of behaviour, isn't that typical something that is starting to "die" ?

And how do I un-solve this ? I missed a button, and pushed "Choose as best solution" or something...

Must be something your doing for it to be intermittent, are you running anything else in the back ground

Good question.. Will investigate this later.

But you don't think it can be psu or hdd related ? Something about to die or something...?
Experienced something like this with an old hard drive, but my current harddrive is SSD. But SSD either work or not ??

if you don't find anything and you have access to other parts try changing things 1 at a time. rams the easiest to swap out then maybe psu and hard drive

I had 4 RAM-chips.. Tested them 1 by 1, and are now running with only 2 of them. Didnt find anything in the memory tests, and the problem still occured however I matched 2 memory chips from the 4 I have.. But I think I can atleast test another PSU and possibly an hard drive as well (if there is any way to move the OS from one hdd to another..)

Do a fresh install and try it first, don't copy in case there's a corrupt file on hard drive

I've upgraded from Win8 (edu ed) to Win10, but I've lost (or not saved) my licence key.
Is it possible to do a fresh install without it ?
