In case you are having issues with your Random Access Memory (RAM), you can solve it by following these instructions.

1. Press Start and type ‘mdsched’.
2. Select Windows Memory Diagnostic.
3. Select ‘Restart now and check for problems’.

If Windows find any issues change your RAM.

In case you have multiple RAM sticks on your Motherboard you can try to boot with only one of the RAM. If the PC starts up normally you can use it until you get a new one in place of the faulty one.

There are many third-party tools to check for hard drive errors, but if you already do not have one, you can also use the Windows default software.

1. Press Start and type ‘cmd’.
2. Right-click on it and select ‘Run as Administrator’.
3. Click ‘Yes’ to continue with administrator permission.
4. Input CHKDSK e: /f (e is an example, you need to put the drive you want to scan instead of e).
5. type ‘exit’ and hit Enter to close Command Prompt.

If it finds any issue you should change your hard drive.

3. Safe Mode

There is another way to start your computer, called safe mode. In this way, only the necessary software runs to boot Windows. You will not be able to use any kind of third-party software.

But if your PC works fine in safe mode, that means your most recently installed application is not installed properly or have some issues.

If you do not know how to boot in safe mode follow the steps below.
