Questions Nerds Often Hear About Computer Diagnostic

When your computer randomly crashes or takes a while connecting to the internet, it’s time to call the computer nerds to a PC diagnostic. We’ll come to your location, or you can bring it to our store in Redding, California. We have the tools to solve problems such as these.

What is computer diagnostic?

Computer diagnostic is “the method of testing a computer device to ensure it is working properly.” 

The type of PC diagnostic that you need is based on the issue that you have. Computer diagnosis is performed using a computer, computer-related product, or a specialized computer diagnostician, like us at Nerds On Call.

With our offer of a free comprehensive diagnostic, we’ll use our tools to identify the problem and resolve it, leaving it better than it was before. 

Typically, your computer will tell you if it is experiencing errors in its hard drive or software programs, and how to address it for repair. Once the problem is found, us Nerds can make recommendations for repairs or replacement, and take care of them all from start to finish.

Why is my computer so slow?

A slow computer can be caused by several reasons, with the top being that you have too many programs running. These programs ultimately use a lot of power, which impacts your PC’s memory and processing speed. 

You may also have too many files in your computer’s system, which determines how much space you have in your overall system. If you hear your fan blowing harder than usual or hear it clicking, it’s time to get a quick fix before it starts to overheat and lead to hardware failure. 

Perhaps your software is simply outdated; either way, there are too many computer culprits to count. In layman’s terms, your PC snacked on too many computer chips and now it’s sick. 

No worries, just call the docs at Nerds On Call. We know that every computer is different and can use our PC diagnostic resources to make your laptop even more chipper with a bigger byte than before, no matter the problem.

Why does my computer keep crashing?

Because of the hardware and software that keeps a computer running, a PC crash is inevitable and is disappointing to say the least. When your computer is in trouble, call the screensavers here at Nerds On Call for a full review of what could be wrong.

What we’ve noticed from our experience is that each computer has a unique way of crashing based on how each user handles their PC and what is downloaded within it. 

With so many programs installed, the Central Processing Unit (CPU) – which is like the brain of the computer – can become overheated and “pass out” by shutting down. 

Another issue we see a lot is insufficient RAM capacity which is typically filled with files like pictures, videos, and unused software programs. 

A clean sweep of these installations can clear up some RAM to help your processing unit run smoother and prepare your computer for our Nerds On Call signature system improvement process.

How can Nerds On Call fix my computer?

At Nerds On Call, our most popular service is called the PC Tune-up. With that, we look for viruses and spyware, clean up temporary internet files, and make your computer as fast as possible. 

Other issues Nerds On Call fixes are:

  • Cleaning up the PC registry
  • Defragmenting your laptop’s hard drive
  • Repairing significant RAM and CPU issues

There are a lot of programs in your computer, and they get stuffed in your start menu, so when your computer starts up, multiple windows pop up and slow your computer down. We clean all that up and make sure useless programs are no longer causing an issue for your PC.

Use our contact form to tell us what’s going on with your computer.

Nerds On Call is here to help!

We can run a performance monitoring during your PC diagnostic to re-stabilize your operating system, and reliability monitoring to identify your system’s weak points and restructure them to create a solid connection once again. 

Let’s add that with our free comprehensive computer diagnostic in Redding, California, we’ll introduce some installation and troubleshooting techniques to help you maintain the network and software applications properly.
