Sudden low fps in all games since yesterday

[Azark]

Hello.

I came to a problem and I can't seem to know what the hell happened 🙁

I have a computer for quite some time now. Specs below.

GPU: GeForce GTX 960
CPU: Intel Core i5-2500k @3.30 ghz
PSU: Thermaltake TR2 RX 550w
Memory 8 GB Kingston
1920x1080 144 hz
Windows 10 Pro

Few months ago I upgrade GPU from HD 6850 to this GTX 960, everything was fine. Now after playing for almost 2 months, from yesterday I started experiencing sudden fps drops. All games, windows take much longer to load and fps is cut by half. For example in cs go i used to have 280fps, now 180 - 100. Even games like Postal 2 lag now, I don't understand what is going on. CPU and GPU temps are fine, did tests, tried downgrading gpu drivers, tried reinstalling windows but still same problem. No weird noises are coming out from pc either. Anyone is able to help?

This is indeed strange, have you checked temps of both CPU and GPU while playing games ? as this could be an overheating problem causing your computer to slow down.

 

[Azark]

Yup, here are the temps. First is idle on desktop, other is after 30 minutes of cs go.

have seen the same symptoms from those infected with bitcoin miners and other malwares.
keep a close check on system processes and make sure you recognize all the start-up processes. they are good at hiding these buggers in common program or Windows folders with common executable names.
try MalwareBytes.

also could be some bit of hardware going bad.

No way it's malware, I did a clean install of windows today nor download anything suspicious. All downloads on my pc are through steam.

If hardware is going bad, any suggestions what could it be?

if you've just totally reinstalled Windows, have all the updated drivers and BIOS, have not installed anything else, and you are still having these issues it is more than likely a hardware problem.
but, if your games are stored on a different hard disk than Windows any malware present will still be there even after reinstalling Windows.

very possibly a hard disk slowing down, memory having trouble, power supply not offering enough power.
run disk check for drive errors. run memtest for memory errors. try reseating components into their slots.
if these show no results; the only way to tell for sure is try replacing components and see which alleviates the problem.

im a bit worried as to why your CPU was running at 100% CS:GO isn't that much of a demanding game and shouldn't of been running all your cores at 100% this is a possible reason as to why you are experiencing frame rate drops if your cpu is at full load ur GPU will bottleneck which shouldn't happen on your setup, go download a program called Combofix from bleepingcomputer, install this onto a USB stick shut down your pc and then boot it in safe mode, run this program it will check for any bugs/conflictions on your computer and fix them, if it still doesn't work after that we need to look into other idea's

Combofix is only a malware/spyware detection & removal application. it has nothing to do with determining hardware conflicts or fixing Windows driver issues.
it is a less known and rather unreliable program compared to Malwarebytes Anti-Malware.

Jesus, stop with these malwares, I would understand if I would watch porn 24/7, download movies or programs to this pc, but it was always used only games through steam and facebook, etc. I am serving in army so not even using this computer super often. It's 4 cores, 1 core is at full load, isn't it normal?

It's 4 cores, 1 core is at full load, isn't it normal?

depends on what you were doing at that moment. if the system is idling, then no cores should be at 100%. if there's an application running that makes use of multiple cores than they should all be near the same %. if the application running is built for single core use then a single core % should spike.

something is most likely running in the background and making use of your system if your CPU and/or GPU is spiking to 100% while not in heavy use.

one thing you can try is setting the CPU speeds to a constant 4.4GHz, by turning off the power saving features.
also, clock your GPU to it's default speeds manually with something like MSI Afterburner.
this should keep either of them from dropping to lower speeds while gaming, if that is what was happening.

Weird, when i change power plan settings from balanced to high performance, click ok, open same window again and it's back to balanced with no changes made.. Any ideas why it auto resets to balanced?
