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. Tried in safe mode but still slow and 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) and the clock speed is at 2.2ghz (turbo clock).
I tried resetting the bios setting (pressing f9 in the bios) but nothing change. I tried running CPU Stress 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, 8gb ram, 128gb ssd
Does someone know what happened? Thanks for your help.

I have a ThinkPad X1 Carbon Fourth Generation here. i7, NVMe SSD drive and it is very snappy. Have you updated all the drivers (loads them including today). Is the system updating Windows? That will slow it down and updates do not constantly use CPU. – John – 2020-02-21T02:24:55.767
It's not just CPU usage that can make a PC slow, also check out memory, disk and network usage – kurdtpage – 2020-02-21T03:29:22.940
Task manager in safe mode don't show disk usage so i don't really know, but it booting up fast like a ssd should so at least it is not a hardware problem. I tried running memory test in the included lenovo diagnostic and it passes every test. I Will try installing Windows XP which I somehow have in my flash drive to see if the problem is in Windows 10 – Xubuntu121 – 2020-02-21T03:59:02.553
John, I haven't updated any driver. I also don't know if Windows is updating because it often run in background and downloaded automatically when I connect my laptop to internet, it could be the problem. – Xubuntu121 – 2020-02-21T04:02:18.253
