At the end of my rope with this pc!

Thats the thing though with mine it just seems to be a cluster of random issues with no rhyme nor reason behind them every diagnostic I run seems seems to find nothing wrong.
 
I thought id chime in as you have had some similar problems to me but some other random stuff as well. I was having random lock ups a while ago, tore my hair out trying to figure it out(even buying a new PSU) Turned out my GPU was sagging too much, after re-seating it and propping it up ive not had any problems. It's probably not your problem but when you are at your wits end and dont know what to try next, its worth a try!
 
Just purchased the Seasonic Focus gold 850w.... might be slight overkill for my needs but gives me more expandability for the future. Here's hoping it solves my issues!

You deserve a break, hope it works out for you.

If it works at least the Super Flower is still under warranty?

Thanks Plec, I appreciate that.... yeah the Superflower still has 6 months left on it. I think as I've said before it either solves my problems and I RMA the old unit and get a spare back or it doesn't fix things and I've then still got a spare unit I can throw in a secondary PC. I am going to pick up a psu tester as well.
 
I had similar problems to yours with a pc build 3 or 4 builds ago. After a bit of googling someone mentioned an issue that they had with aida64, which I was using at the time. I see you're using aida64 too, I stopped using it and my problems disappeared. Doubt it's the reason, but as your struggling...

So a few months ago I pulled the trigger on some upgrades and the system has been running flawlessly until fairly recently.

I started getting stuttering in games, frame rate drops and on one occasion artefacts! I naturally assumed my GPU is on it's way out but am wanting to be certain before RMA'ing the card.

I've tested my GPU vigorously running Furmark for over 7hrs with a +500 memory clock without issue.

I've run Memtest86 overnight without issue.

My NVME, SSD & HDD are all okay.

I've updated BIOS and all drivers.

Used the below overclocking guide.

GPU temps have never been above 80c!

The PC was running fine, dialled back some game settings and saw a huge boost in frame rates, still some stuttering though on occasion.

Which brings me to today. While playing games I've noticed screen tearing, despite having gsync enabled.

More frustratingly, I've had 3 random restarts, 2 system hangs and failure to post that I needed to clear the cmos to get back and have reset the bios with optimized defaults.

I feel literally at the end of my rope now!

Any and all suggestions as to what else could be going on are welcome!

So trying to help a bit more given the frustration I know it can cause I have sympathies.

Here is what I believe can cause stuttering in games.

1 - I/O on storage media so e.g. ssd or hdd. This could happen if you run out of ram to an extreme enough level that the game itself starts been swapped to the pagefile instead of physical ram. The easiest way to rule this out is to play the game without a pagefile enabled on your system, if it stops, thats the cause. It can also happen without pagefile been the cause tho, so e.g. if its game that naturally has a lot of i/o such as division 2 and the storage media simply cannot keep up.
2 - Saturated CPU, in my experience if a cpu is maxed out you will get stutters. Unlike with a maxed out GPU which has a much more elegant drop in performance (providing no vsync).
3 - Saturated GPU with vsync enabled, if vsync is enabled and the GPU cannot maintain target FPS, it will feel stuttery as the game has to jump down to a another multiple of the monitor refresh rate so e.g. from 60 to 30fps.
4 - Unstable GPU, so if the vram is unstable it may yield stutters, as ECC is not a performance penalty free technology. I also think after some research a unstable GPU core clock can cause this also, if you think on a driver crash usually its proceeded by a big long stutter, sometimes you can get "near misses" where the GPU will just momentarily freeze then recover and this could be perceived as a stutter.
5 - Security software, things like ASLR add a performance hit (windows by default doesnt force it on tho, however 3rd party software might), however what is more likely is if you have an anti virus scanning files been read from the disk, and if you playing a high i/o game, that can lead to the a/v triggering the stutters.
6 - IRQ conflict, a easy way to see if you have IRQ sharing is ironically using the tool that toggles MSIX mode, so grab MSI_util_v2 from the internet, run it and check what IRQ your GPU is using and see if any other device has the same IRQ on your system. Now bear in mind IRQ sharing does happen routinely on many systems without visible issues, so a shared IRQ doesnt mean that is the cause of the problem, its just "possibly" the cause. If the IRQ is a negative number such as -13 it means MSIX is already enabled for that device, modern motherboards may already be using MSIX for some devices, mine e.g. by default activates it for the onboard nic's and USB ports. My GPU in legacy IRQ mode shares with my soundcard and my SATA controller. The latter wont be hardware fixable as its wired on the board, the former can be done by moving my soundcard to another slot. A software fix however is to activate MSIX on the GPU. Which is done by ticking the msi box next to the GPU in MSI_util_v2, hitting apply and then rebooting.
7 - Bad drivers, a bad driver could possibly cause stuttering, I dont think its common now days but its possible. It could be any driver even a non obvious one such as e.g. network card driver.

Personally I would not expect bad system ram to cause stuttering, usually bad ram is just system instability so an OS or application crash.

Graphical defects in 3d applications aka games, the only thing I have seen cause that is bad vram, whether its faulty or clocked too high (usually the latter). Decrease the clock on your video card memory (even if its already at stock) to see if this may be the issue.

I was starting to have stutters in division 2, I did all of the following at once which has solved it, but dont know which yet was the magic bullet.

1 - I disabled my pagefile (I want this to be temporary even with 32 gig of ram), as loading the game causes the page file to start been utilised, I have enough ram tho that it shouldnt have been swapping out any in game assets, but to be sure I disabled the pagefile. I am uneasy about this tho as my virtual memory load is hitting circa 80% now with no pagefile.
2 - I disabled process hooking in HMPA on the game, I excluded all game files in nod32 for the game, and also forced disabled windows ASLR on the game process.
3 - I increased the voltage on my GPU one notch from 1.03v to 1.043v. Since some of the stutters were in excess of a second and I observed they were happening even at idle i/o and low cpu I actually think this is the most likely magic bullet.

Sometimes in game settings can also help so e.g. if you have i/o causing it then reducing options in game that in turn reduce i/o can fix it such as "streaming distance".

had similar problems it was a faulty sata cable
pc never faulty when testing only showed up in games
and not all the time went days without a problem then stuttering and tearing then crash
might not help just my two pennies worth
 
So the new PSU is installed, which almost ended in disaster as my little one knocked into me and I dropped my 360mm Rad on to my 1080ti! Luckily I had a bunch of cables in the way which took the brunt and all seems to be working as it should with no visible damage to the card or anywhere else for that matter.

Apart from that installation was mostly easy, though the 2 8pin cpu cables are stiff as hell and a pain to manoeuvre with the connectors being split into two. There was swearing from me with that due to my sausage fingers...

I'm going to run aida64 overnight and see how things go but initially I'm not noticing any problems. For one I'm not getting any strange noises from my PC now, no random drill like noises or anything else... It's quiet as anything.

Quite surprised by how much smaller the Seasonic unit is to the Superflower though.

Good glad man.

But my new PSU is actually a source of noise :(

Antec HCG (apparently rebadged seasonic focus plus).

I noticed in division 2 noises kept coming on and off I could even hear with headphones on, , I put ear to PC was unclear the source, I then toggled the PSU dynamic fan mode and the noise stopped. The dynamic fan mode makes the noise when PSU is under load. Its quieter with fan always on.

It also creates electrical interference to my sound.

But like your observation on size the PSU is smaller than my older lower capacity PSU.
 
So far so good! I had to cut my Aida64 run last night as we went onto emergency credit on the electric meter but after 2hrs all was looking good, despite temps being higher than I'd like hitting a max of 87c

@orbitalwalsh @Plec Do you think with my temps getting that high I'll be able to try overclocking again?
 
Just out of curiosity, what are your idle temps?

The 9900K as you know has a thermonuclear core - and if you're happy with restricting yourself to a lowly TJ max of 115 degrees :D - then you have plenty of headroom.

How did you apply your clock before? Were you batting for 5GHz or a happy medium of lower voltages and respectable clock?

Also, what does your vCore read when running aida at stock?

EDIT: That said, i would obviously get some general browsing/gaming under your belt first and validate stability and lack of stuttering. I've had systems stress tested for 24 hrs straight and then proceed to BSOD while I'm catching up on F1 news :/

*i don't stress test like that anymore - purely because of the latter and the fact that systems are way more resilient and easier to clock. I only do a few runs of differing tests now - for immediate signs of weakness and thermal issues - I then test via general day-to-day usage.
