A: My computer has a problem. It is working slowly.
B: To find the symptoms you need to check your computer's devices?
A: First, you should open the Task Manager to see if the computer is working normally.
B: I opened my computer and the hard disk works 100%, but afterwards (after. that) it slows down
A: Then, I think that your computer might be infected. You have to install new windows .
B: I already did that like you taught me.
A: It’s not difficult. First. you can download windows.
B: Okay, I have downloaded it. What do I need to do next?
A: Next, click the windows exe file and (then) select the desired drive. (Finally) the system will install it automatically. You just have to set the date.
B: That was successful. Thank you. It was not as hard as I thought. I’ll be able to help my friend now. He had the same problem as me.
