Lag / Stutter and general slowness when playing games but fine when not

Hello,

The background
I've been playing mainly WoW and Overwatch with all settings set to maximum for a good moment with no performance issue at all. Two weeks ago, my power supply died, which I replaced. Unfortunately, when I restarted my computer I had an error message preventing me to start Windows causing me to format my main drive (SSD) (actually I also formatted my secondary drive (HDD)) and install a fresh copy of Windows 7. I installed the most up to date drivers for all devices and everything works fine... except when playing games.

The problem
Overwatch is installed on my SSD. I notice a significant amount of stutter in the game, to the point where I had to stop playing because it was not enjoyable / almost unplayable. The game lists an FPS ranging from 45 to 60 with all settings at maximum and a ping of 45-55ms, which I hear is not exceptional but should not cause major concern.

World of Warcraft is installed on my HDD. This game plays smoothly, however from time to time the game lags for a good 2-4 seconds, which is demonstrated by actions not causing a reaction but the game still otherwise looking like it's working.

The analysis
I've been looking everywhere to find where I was wrong. I double-checked every logical driver (network adapter, GPU, CPU, mobo). I downloaded Real Temp GT 3.70 only to discover that my CPU temp was at a whopping 90-98C. I fixed this by installing a CoolerMaster 212 Evo and applying Arctic Silver thermal paste. This resulted in a drop to 38-45C (light browsing, some applications open but no intense processing). GPU is sitting at 40-44C.

As you'll see from my build, I have plenty of RAM (although I did have to take a 1x4Gb RAM out to correctly install the heatsink and fan of the 212 Evo cooling system). I have tried switching to another router, using a cabled connection to the router, etc. No change at all. It's also worth noting that I nobody else in the family has complained of similar issues and we are two gamers (other gamer playing FF XIV).

Finally, I listed the different installation (SSD vs HDD) of WoW and Overwatch as this would almost rule out the possibility of a faulty drive (unless they are both ruined due to the previous faulty PSU or due to me being careless and destroying them unknowingly).

The build

Gigabyte Z68A-D3H-B3 Intel Z68 LGA1155 MB
Intel Core i5-2500K 3.3Ghz Unlocked LGA1155 CPU
Cooler Master Hyper 212 EVO - CPU Cooler with 120 mm PWM Fan
Running on Windows 7 Ultimate with all updates done.
No overclocking of any sort was ever done on this computer.
All parts (except for PSU and wifi receiver) were purchased in early 2012, the wifi receiver was purchased in 2015 and the PSU obviously was purchased two weeks ago.

The question
What would be the following course of action to identify the issue that I have here ?

Please do not hesitate if I have not provided enough information to correct me. I will edit this post.

Best,

That groove on the Evo allows the fan to slide up. Trying to attach a 90mm fan wouldn't work out to well. Inginuity can work wonders though. A couple things. I'm curious what the memory test would...


The biggest change I can see is that you are using 3 RAM modules when you should be using four, which you were before and everything was fine. You now have 1 module without a mate. Dual channel? 2 modules work in tandem. Now it's not working right. The RAM modules aren't configured right and you have problems. That's to be expected imo. TOuch something metal prior to touching that lose, or any other, RAM module. Unplug your computer and hold the power button for a few seconds. Put that RAM module back in and clip the fan to the Evo above the heatsink fins on the RAM module of course. Be careful. No breaking the CPU or cracking the motherboard. Very good idea to add an additional "pull" fan(High static) because the airflow will be a little less. Compensate. I'd also reset your CMOS after you replace the RAM module. Put all your BIOS settings back where they should be. The Evo does come with two extra clips for an extra fan. I'd also run a memtest when you get back into Windows. Make sure there wasn't a static discharge or any other mishap. Press and hold the WIndows icon button on your keyboard. Tap the R button. Type "mdsched.exe"(no quotes" into the search/run box. It will ask for permission to restart. Give it time. Do NOT interrupt that process.

I'm very sorry this wasn't clear in my original message but I actually had the occasion of testing the new power supply with the stock heat sink and PSU fan (i.e. before removing 1x4Gb RAM) and the problem was already notable. This is what got me looking at CPU temperature in the first place.

What one friend suggested is to try and find a smaller fan that I could attach to the 212 and put back the additional RAM module. I am open to this idea but I am not confident this would solve the problem existed before removing the RAM module.

I'm curious what the memory test would say. How are your temperatures and loads in your games. I am wondering if thermal throttling is involved.

I have MSI Afterburner's monitoring program running with The GPU termperature, load, core clock and memory clock as well as the amount of VRAM that is being used. All these choices and more are available in your settings. I also have the FPS, CPU temp. and load and the amount of system RAM in use showing in the OSD. This way I can see at a glance how my system is "feeling"
