Computer extremely slow, even after formatting hard drive

Hello, how are you?

Welcome to the Microsoft Community!

My name is Paloma B., I'm an independent advisor, I'm here to help you in the best possible way.

Analyzing the information presented, I recommend that you follow the guidelines below, please, to try to solve this problem.

First, I recommend that you check and run any pending updates on WIndows Update, please:

Press the Windows key > Settings > Update and Security, after that click on the button Check for updates, in case, please make all updates.

Update even the options.

As additional procedures, I recommend that you please follow the guidelines below:

Method 1

For clean boot follow the steps below:

1. On the Desktop, simultaneously press the Windows + R keys to open Run;
2. In Run, type MSCONFIG and click OK to open the System Configuration;
3. On the Services tab, check the option Hide all Microsoft services and click Disable All;
4. Click Apply and OK;
5. Restart the computer.

NOTE: This procedure disables all third-party services and programs. You can later, if the problem is solved in this way, selectively enable the programs and services that will start with Windows, instead of keeping all disabled. If the problem returns after activating the startup of a specific service or program, the problem is exactly in the startup of this software and it is recommended to remove it.

Method 2

Clean up temporary system files:

1. On the Desktop, simultaneously press the Windows + R hot keys to open Run.
2. Now type TEMP and click OK.
3. The TEMP folder will open, please permanently delete all files inside the folder, if some files are not deleted it will be normal as they may be in use.
4. Again press the Windows + R hot keys simultaneously to open Run.
5. Type %TEMP% and click OK.
6. The %TEMP% folder will open, please permanently delete all files inside the folder, if some files are not deleted it will be normal as they may be in use.
7. Again press the Windows + R hot keys simultaneously to open Run.

3. In the Ndu folder, find the file/key named "Start", double-click on it and change the "Value Data" field to 4;

Check for performance improvement.

Method 4

for

4. Now, uncheck the Automatically manage paging file size of all units box;
5. Check the unit that contains the so-called paging file, click the Custom size button.

Once this is done, you are able to point out the initial size and the maximum size of the virtual memory usage. It is recommended that you check, as a minimum, a space equal to the size of your RAM memory installed on your computer. That is, if you have 4 GB of RAM, also point to the same 4 GB of virtual memory.

Method 6

2. Type in the blank field

services.msc

and press ok;

3. Click on the "Add" option;
