If nothing works then i will reinstall it. But last time i reinstalling windows i need to run the setup inside windows. It won't allow me to reset via booting to usb drive so it will be hard to do, also my usb drive is broken and I don't have a second pc/laptop to get an installation ISO.

When I boot up my laptop today it is very slow, it need 1 minute for the login screen to show up but the booting speed is normal. The mouse is not affected it just the UI is very slow. Restarting the laptop 3 times and even in automatic repair it still very slow. Then i start in safe mode and login, when i open Task Manager the CPU utilization is 0-3% (the highest is 30% from windows explorer and it only last for a second). The clock speed is locked at 2.2 ghz (normally it would be at 2.4-2.6 ghz) I tried resetting the bios setting (pressing f9 in the bios) but nothing happen. Tried running CPU Stress test in diagnostic tool and it seem to run normally (the cpu got hot and the fan is louder) so the problem only happen when the laptop got to windows. My laptop is a Thinkpad X1 Carbon (3448) Spec : Intel i5-3427u 1.8 ghz up to 2.6 ghz 8 gb ram 128gb ssd Does someone know what happened? Thanks for your help. Edit: I also used Intel XTU yesterday and changed turbo power max but resetting it to default because it don't do anything, then uninstalling the app. I don't know if it started the problem.
