Before I start talking about my problem, I will list my PC specs and other stuff needed.
- OS: Microsoft Windows 8.1 Pro 64 bit
- CPU: Intel® Pentium® G620 2.60 GHz Dual-Core
- GPU: NVidia GeForce GT610 1024MB DDR3
- RAM: 4 GB of DDR3 RAM
- PSU: Free Silent 500W Power Supply
- Motherboard: ASRock H61M-DGS R2.0
(the FPS is NOT because of my specs, these worked fine a day ago, now it's all starting to lag.)
Here is the problem.
Two days ago, everything worked fine. I was able to get a stable 40-50 FPS when playing CS GO on Casual. Yesterday, I cleaned up my PC using CCleaner, installed latest GPU drivers and cleaned my PC of dust. When I booted the PC up again, games were seemingly slower, was able to play them with fine FPS for like 2 minutes and then they start progressively going down to 10-20 FPS.
(before you say the problem is because I may have damaged some chips while cleaning, the problem is not of that, I was very careful and double-checked for that, no problems).
What I tried:
- Cleaning up my PC with CCleaner.
- Installed latest drivers for Realtek LAN and Audio, and for my graphics card. And everything else using DriverBooster.
- Putting Power Saving mode on High Performance.
- Lowering the games's graphical settings.
- Checked my hardware for failures:
CPU (used Hot CPU tester Pro): Fine, no overheating.
HDD (used HDD health to monitor): Health: Excellent, temperature is good.
PSU: Checked to see if the fan is spinning, it is and it is running in good shape.
RAM (used Windows Memory Diagnostics): No errors.
GPU: Good temperature, fan is spinning, no problems here.
I don't know what else should I do. Don't say to buy a new PC because I don't have the money for that.
Any help would be appreciated, thanks.
