My dual boot linux-windows got slow on both operating systems. The GUI components render slow and sluggish.
I've tried everything I know but haven't been able to pinpoint the issue.
- Malware: I ran kaspersky rescue disk, ClamAV in Linux, rootkit scanner, Malwarebytes in Windows, they all find nothing.
- Disk: I checked OS SSD performance with crystaldiskinfo/mark, all good
- GPU: monitoring doesn't show anything extraordinary, Furmark stress test went fine, temperatures are normal.
My system is a laptop, i7 with an Intel HD GPU and NVidia 740m GPU.
The slow GUI rendering for everything is maddening to me and I don't know how to troubleshoot this further. Any suggestions?
Edit: on inspecting the picture closer, I noticed 'CPU performance limitation reasons'. The reason given is frequency clipped due to external prochot assertion
.
So the CPU ís getting too hot but it doesn't stand out because it get's clipped. So why is it getting too hot?
I cleaned the air vent not long ago. Maybe thermal paste needs replacement?
