Unknown Cause For Slow Performance

I bought this laptop (Aspire E 14 E5-473-31TG) last year, and this is the first time I see my laptop getting massive drop in performance. It started 2 weeks ago. I was doing 3D Modelling using Blender in the morning. I put it to sleep, and when I use it in the evening, the performance is low. I can still do modelling, but the process is taking a bit longer than expected. Not only that, but it affects all my games, the browser, and basically everything. Opening File takes more than 3 seconds, which is not normal because it usually takes less than 2 seconds to open. Watching YouTube videos is also not good. I get constant lag spikes in the videos. It takes a major effect on my games especially. From a stable FPS (maybe 30-40 FPS) to less than 15 FPS, with lag spikes.

So I decided to format my laptop. The performance went back to normal after formatting. I continue to use the laptop as usual, when this morning, the same thing happens again. Slow performance. Even as I'm typing this right now, I see that the words appear slower than expected. For example, each letter typed in takes about half a second to appear. So I format my laptop again, hoping I can find the cause of this. But after format, the performance is still slow. I decided to check the speed of the CPU. My laptop uses Intel Core i3 2.0GHz. When I check Performance in Task Manager, the speed is 0.5 GHz. I'm not sure if this is the default speed of the CPU. I have no idea what's causing this performance drop. I seriously need help, it drives me crazy.

Hi,
Could you please tell us the OS you are using, have you tried High Performance Power plan? Also use Malwarebytes free to scan for any virus infections.

I'm using Windows 10. Yes I tried High Performance Power Plan, still slow. And later I'll try to use Malware Bytes
