Issue: FPS drops are suddenly appearing after months of lag-free gaming. PC was built into a new case and first no real problems showed up. The next day massive FPS drops began that are 10 seconds long and occuring probably every 30 seconds. Electrical crackle is audible while the FPS drop is happening.

Hi guys,

my PC:
  • ■Mainboard: MSI 760GA-P43-FX
    ■CPU: AMD FX-8350
    ■GPU: MSI GTX 660Ti
    ■OS: Windows 8.1 64-bit
    ■PSU: Thermaltake Berlin
I've come to this site to find answers for a lot of questions about PC buildung etc.
Sadly I now have to write here since I think this is out of my range of problem solving ability. Plus I am just so frustrated about these sudden appearing FPS drops. There is also a weird audio crackling connected to the drops as I will try to explain in very bottom part.
I will refer to yesterday as the 31/12/2016 and today as the 01/01/2017.

Yesterday I played CSGO fluently. No stutter, no nothing. Today in the morning literally out of nowhere I experienced huge FPS drops. Like from 200-150 to 40-60. Frequently. Non-stop.

So the weird thing about this is that at one day everything is just was fine and the very next day I get these insane FPS drops that last exactly 10 seconds long like it's timed or sth. I don't know what the difference was to make these drops happen. I honestly have no idea. I sat here the whole day trying to figure it out and have been through so much frustration already that you are my last hope 😉 I try to explain the situation with some details.

Recently I brought a new case. The Fractal Design Define R5. So two days ago I took out all the parts out of the old case and put them into the new one and I added a 2TB HDD.

Yesterday I played with the PC in the new case and everything was fine. The next day I wanted to start using my new 2TB HDD. As I didn't appear under "Computer" I started to format it with the Windows partition control or whatever that is in english.
I unchecked the box at "fast formating". (I thought if I format this drive I might as well do it "slow/full" since it's the first use. Now I am thinking about my little peanut brain trying to slow format a 2TB HHD.) I soon realised that this was a big mistake since it took half an hour to reach 3%... So I canceled the format und created the partition with "fast formatting".
I can use the HHD and everything seems fine. But I think it was at this moment in the timeline that the FPS drops started. Later I deleted the partition again with difference to the FPS.[strike][/strike]

Another thing is that I installed the new NVIDIA driver. At the same day I got the massive drops. I tried to fix it with uninstalling the driver with DDU and install an old one from a month back. But there was no difference.

In the process of moving everthing into the new case...
I unmounted the CPU cooler and applied new thermal paste because why not. PC was running two years in that setup probably.
As I unplugged all the cables from the mainboard there was one SATA 6GB cable which didn't come off easy. So I really applied pressure and tried to get it off for some minutes until I decided to move on and not rip the whole socket off the mainboard. I think it was just the connector of the cable that wasn't working or sth. Anyway the cable works and I can use my SSD at that plug. And I don't think I could have damaged the board in any way since the cable/connector works but how do I know...

As I looked at my PSU I just saw sooo many dust that I to open it after all these years and indeed it was necessary. Got the fan out and cleaned everything. Put it back to together with the screws. That's it.

I actually forgot the CPU power cables from the PSU to the mainboard after 3.5 hours of mouting little screws in the sunshine. So I sat there and my booted the PC like 5 times before I realised they were missing. Didn't seem to hurt the mainboard/CPU since yesterday everything was fine.

There are four 140mm fans in the case atm. At first only two but later three of them connected to the regulation in the case itself which is powered via SATA. The other two later one are/is powered by the mainboard SYSFAN1. I tried to use SpeedFan to regulate the speed of the fans so that they would be quiet at low temperature. I experimented a lot. A LOT. Just changing back and forth.
At the end I can say that I'm not gonna use SpeedFan. The CPU fan is now auto regulated as it was before and the one on SYSFAN1 runs at 100% always. The case has a control switch for the other three fans. However the FPS drops didn't go away. (Which wasn't the goal here with the fans but I played way too much with it probably. Little overheating was the result I guess but never over 63°C.)

As I searched for FPS issues online I came came across AMD thermal throttling again. The FX-8350 should throttle at 61°C which is easily reachable if the CPU fan speed isn't adjusted. But FPS drops were still happening at ~50°C or lower. The CPU hit over 60°C multiple times during my fan experiments. That explains some of the drops due to throttle but not the insane FPS drops at low temperature.

I tried Windows restore points aswell with no success.

Now to the audio. My headset (HyperX Cloud2) is plugged the backside of the mainboard with the red and green 3.5mm connector. Yesterday I noticed that there was crackling when no sound was playing at all. It was not noticable while music was on or the game sound was on. When I scrolled in my browser it crackled every time I scrolled with my mousewheel.
Now I just realised that when I get normal FPS (like 200) there is a constant noise audible. It's quiet and reluctant. But while the ten seconds my FPS are dropping (to about 50) there is a way louder electrical noise. It's like brrrrrrrrr. I don't know man. It just changes as the FPS drop is happening and it is definitly connected!
I never had any crackling before in the old case. It started in the new one. (But it's still plugged directly into the mainboard.)

I can image that this is a hardware issue that's why this thread is in "motherboards". I have no clue what could have caused this random change. My first guess was that playing with all of the fans messed something up. That is still a good reason for me but after I uninstalled SpeedFan etc nothing changed. Still drops. I don't know what I changed that it lags like this.

Should I try to get my GPU out and in again? Maybe it's the canceled formatting. Maybe it's the new driver. Maybe something with board/CPU/GPU is wrong. Maybe it's just because the time went from year 2016 to 2017 and everything just shattered. Idk lol I'm pretty much done.
I could record a video of the FPS drops maybe later.

Sorry for some spelling mistakes or bad englando. It's 2 AM and I'm not a native speaker.
I would really appreciate any help you guys can give me to fix these FPS drops.

Greets,

EDIT: I totally forgot to ask:
Is it normal that in HWMonitor my FX-8350 says 4100MHz on all 8 cores when this CPU is 4GHz meaning 4000MHz without any changes in clocking. I didn't change anything regarding this in the BIOS. Must automatically set by then right?
 
UPDATE:

This seems to be thermal throttle issue over all. Just lowered the settings in the BIOS. In the H/W-Monitor tab:
"CPU Smart FAN Target" = 45°C (was 50°C before, obviously too high)
"CPU Min. FAN Speed" = 12,5% (as always)
After testing this ingame the maximum reached temp. was 58°C. No FPS drops occured. I hope this is fixed. (I changed one more setting. Read below.)

Two weeks ago I wanted to get my SSD to AHCI. So I did that in Windows and then turned all options I could in the BIOS to AHCI.
Under the Integrated Peripherals tab I set "Extra RAID/IDE Controller" to "AHCI".
Under the option "On-Chip ATA Devices" I set "RAID Mode" to "AHCI.
Today when I was changing the FAN target I reversed the "RAID mode" setting to "IDE".
No FPS drops as for now. Issue seems to be fixed. I hope this stays like this. Will update if anything changes.

Overally I am pretty dissappointed with Fractal R5. I brought this get more cooling and a more quiet PC. What I did get was 5 loud fans and a overheated CPU. The features and blabla are nice but how can there be no dust filter on top for 100 bucks? I'm gonna write a feedback on the shop I brought it. I almost destroyed my USB Flashdrive as I tried to get it out of the front panel. On of the top panel plastic nub already broke off after 1 day. Lmao. So many small shitty things about this case. It was brought over 11000 times from the online shop I got it. People actually liked it. That lead to my decision to buy the R5. The case is waaay too heavy. PC probably weighs about 20kg now. Not easily transportable to a LAN.
 
Idk if i'm going to be of much help but I've been suffering from frame drops too, I've only recently got into PC gaming but with a gtx 1060 graphics card and an i-5 6400 processor i shouldn't be lagging in games light overwatch, osu, and minecraft, usually a good game should have about 60-70 frames but whenever i play overwatch i always seem to get 20 and under which is a pain for us fps players, I've tried scanning my computer for viruses, says there are none, looked for something that i downloaded which could have been the cause of fps drops still nothing. I've only had this PC for a month only play on the weekends and i don't want to feel like i wasted 30 pounds of 800 dollars.

One thing i did try was making my games run as an administrator see if that could help.but sometimes my games run smooth and if not most of the time i get frames below 25

 
UPDATE REAL FIX

Disabling "AMD Cool n Quiet" in the BIOS seemed to help a lot with the drops. They were gone after that.
Disabling other "throttling" feature which are there to save power like C1E or C6 state might you aswell.
But as I remember they crashed my system so I had to take out the BIOS battery for a min.
The reason the FX-8350 runs at 4100 MHz is that it's automatically "overclocked" if system/temps allow it. A pretty neat feature.

However I switched the mainboard to the Gigabyte GA-970A-UD3P which was a very good decision. There was definitly something wrong with the over 2 years old MSI board. All FPS drops are gone completely. The board can finally use all of my SSD with 500mbs.
My BIOS settings:
Clock ratio - auto
core performance boost - auto
cpu unlock - disabled
cool & quiet - disabled
C1E support - disabled
SVM - enabled
cpu core controle - auto
core c6 state - disabled
HPC mode - enabled
APM - enabled

What is the meaning of "BIOS" ?
