[Unstable system]Need help finding the reason.

[Hakon]

The last few months I've been having issues every now and then where my system would appear to be unstable. It's kind of hard to describe exactly what "type" of unstability I'm experiencing but to give you some examples I will list the following.

 

- Windows gives me an error saying the memory is full, but when I open the resource monitor I'm at like 14% usage overall.

- Demanding games like Arma III will sometimes crash upon startup or a little into the game, again the error points to the memory.

- BSOD's every now and then, the latest error I got was: "System_Service_Exception win32kbase.sys"

- Low performance compared to the HW I'm using, close to the same performance regardless if I use the 980Ti or the 660Ti. 

- The system generally feels less responsive at times, easy tasks like opening the control panel can cause stutter and hiccups. 

 

I'm not able to pinpoint what triggered these problems to begin with. I've recently been doing some changes in both HW and Software. I upgraded both the PSU and GPU not to long ago, but although not as often I still had the occasional hiccup prior to this. I also changed my RAM sticks a little while ago, now this upgrade might match up more to when the problems started but I can't really be sure. I've also made the jump from Win7 to Win10, but the problems followed me across. 

 

Parts list is in the signature, everything running stock as I need to stabilize it first.

 

1. I wanna start my troubleshooting by looking for HW error as I'm pretty sure it's not Software based considering I'm currently running all stock with a fresh Windows install and all the newest drivers. What I need help with is to find out what software will help me stress the components enough to either uncover faults or rule them out as the culprit. Here is what I'm thinking;

 

Are these good for testing? (Any others I should run..?)

- Memory, Memtest86? Others?

- CPU,  Aida64 and / or Prime95? Others?

- GPU, Furmark? Others?

 

2. Any other reason than HW failure you guys can think of? I haven't dug to deep yet as I wanna start with stressing the HW and look for errors. As I said, I'm running a fresh install of Win10, all the latest drivers and all temperatures are normal.

 

Any input is very much appreciated. If anything comes of as unclear, feel free to ask.

Have you checked for viruses and root-kits? The memory thing could be because of a worm or something.  (boot sector)

Os reinstall, drivers,

You should just go through a very in depth checklist:

 

1. update drivers

2. Run memtest

3. Run dskchk

4. run a virus scan

5. update BIOS
