How to Analyse Your Computer's Hardware
A regularly occurring problem for PC users is the loss of performance of their computers when performing common tasks. This situation can be due to hardware failures, errors in system files, outdated drivers, amongst other reasons. Fortunately, there are many programs that can help identify problems in a PC by running diagnostic tests, both in its general operation and in its internal (CPU, RAM and hard disk, etc.) and external (peripherals) components. In this article we will take you through these programs.

How to Analyse RAM Memory
RAM memory failures are one of the main causes of system instability. To analyse RAM modules you can use the MemTest tool.Read this article on how to diagnose the PC RAM status with MemTest.
You can also use the Windows Memory Diagnostic Tool, included by default in Windows Vista and later versions. To access it, simply press Windows + R, and when the Run dialog box appears, type the command mdsched.exe and press Enter:
You can even scan your RAM from a Windows repair disk. Ultimate Boot CD also includes tools for this purpose.
How to Scan an HHD or SSD Hard Disk
At present, hard disks are equipped with a technology called S.M.A.R.T. which allows us to obtain information about both the device itself and its state of health. Here are some tools that use this technology to check the status of your hard drive.Note: If the computer does not turn on, you can install the hard drive on another computer (as a slave drive or via a USB adapter) to perform the tests.
HDD Health
HDD Health is a utility that once installed, can regularly check S.M.A.R.T. health attributes and alert you in the case of any abnormality. To quickly access its options menu, right-click on its hard drive icon located in the system bar (next to the clock):
To view the health status of your hard drive, click on the Show HDD Health option. Then go to the Drive tab > SMART Attributes.
CrystalDiskInfo
