CPU performance

[Cathy-50BMG]

i have an i5 13400F, it's just under a year old & recently my PC has slowed down by a considerable amount, & has also been completely freezing. i'm worried i may have one of the faulty 13th gen CPUs.

is there any surefire way to know if it is, in fact, faulty?

for the record, i have an gen 3 M.2 as my boot drive, which i've been told shouldn't be an issue.

Create a new system restore point. Then proceed below steps

Step 1
Please type the following commands in the Cmd application, and execute them with administrator rights

Sfc.exe /scannow
Dism.exe /CleanUp-MountPoints
Dism.exe /CleanUp-Wim
Dism.exe /Online/CleanUp-Image /RestoreHealth

Step 2
Always use SSD or NVME disk for Windows
Use Disk Cleanup tool, to get rid of waste files
Uninstall very rarely used applications and software
Do not use third-party antivirus; instead use Windows Defender
Scan Complete Windows partition
Delete all possible tasks registered under the task scheduler
Disable start-up items under the task manager
Delete or remove all files from the temporary folder C:\Users\username\AppData\Local\Temp
Disable any unwanted services that are set to manual

Step 3
Please type the following commands in the Cmd application, and execute them with administrator rights
