Computer Diagnostic Utilities To Repair and Troubleshoot Your PC

Hard drive health

If you’re experiencing computer trouble, these popular computer diagnostic utilities can help you save money by troubleshooting the PC yourself, without the need to take it to an expensive computer repair shop. Computer diagnostics can be done on several different levels, by running software, visiting sites that can automatically perform checks, and by physically adding hardware to your machine to run tests. Depending on your circumstances, some of these options can help you diagnose problems you’re having with your PC.

Popular Computer Diagnostic Utilities

If you’re experiencing problems with your computer crashing, you might have problems with your RAM or your hard drive. To run diagnostic utilities that can scan your hard drive, you should first determine what model hard drive you have in your computer. Chances are, you have a Maxtor, Western Digital or Seagate drive. The following software can be run, depending on your model:


Western Digital Data Lifeguard


If your computer is unstable, you could be having problems with your RAM. Since the RAM stores programs that are running in memory, a bad stick of RAM can cause your computer to crash, reboot or suffer from low performance. If you suspect you have a problem with your RAM, be sure to download and run Memtest86. Windows 7 and Windows Vista have a memory checking utility built it. To run it, click the Start button and type in mdsched and hit return. You will need to reboot to run the scan.

Diagnostic Websites

When it comes to diagnosing and benchmarking computer problems, there are a multitude of website that can provide you with services. If you’re looking to test your broadband connection for speed, you can try Broadband Reports and run their tools. If you’re looking for an overall diagnostic website, PC Pitstop has been around for years.

Hardware Diagnostic Tests

Sometimes a computer is in such bad condition that it will not even boot. To make matters worse there is no way to figure out what piece of hardware is bad. If the BIOS will not produce a beep code, or if your computer is not equipped with diagnostic LED lights, then you have no recourse but to install a PCI Diagnostic Card. This card will produce a numeric code you can use to figure out which piece of hardware has gone bad.
