I'm have trouble with my laptop. It's 2.5yrs old. And suddenly it has become slow. Was completely fine till a week back. Now it freezes on stuff. No noticeable difference during games. Launching of softwares and games is considerably slower. The laptop even takes its own sweet time to boot up. Before it is use to be very fast. I have tried to check for virus, using windows defender and Kaspersky. I have checked for drive errors using the built-in software. I have checked for read and write speeds. These do not seem to have been affected. The task manager also does not show any resources being misused.
I would request someone to tell me a diagnostic software which could tell me the health of the various components of the system. And identify any runtime errors that may be present.
I am trying to find the issue so that I can give it for warranty. I want to minimize the time they would take to fix it.
