Free Desktop Computer Diagnostics

If you are not sure what is wrong with your desktop computer, start with our free computer diagnostics.

We can determine what is causing the problem and identify the repair or upgrade options that may be available.

A computer that will not turn on, will not boot or is behaving strangely does not necessarily need to be replaced. A proper diagnosis can determine whether the problem is related to hardware, software or another issue.

Desktop Hardware Repair

We repair and replace many desktop computer components.

Our Hardware Repair & Upgrades service can include:

Hard drive replacement
SSD replacement and upgrades
RAM and memory upgrades
Graphics card replacement or upgrade
Power supply replacement
Cooling and fan-related problems
Other compatible hardware repairs and upgrades

Desktop Hard Drive and SSD Problems

Storage problems can cause a desktop computer to become slow, unstable or completely unable to boot.

If a hard drive or SSD is still functioning and the data can be accessed normally, we may be able to replace or upgrade the storage and transfer the appropriate data.

If the storage device has failed or important files are no longer accessible, the situation may require specialized Data Recovery rather than a normal repair or data transfer.

Desktop Power Problems

A desktop that suddenly shuts down, will not turn on or shows no signs of power may have a problem with the power supply or another hardware component.

We can diagnose the system to determine whether the power supply or another component is responsible.

Desktop RAM and Memory Upgrades

Insufficient or faulty memory can contribute to slow performance, crashes, instability and other problems.

When compatible memory is available for your system, a RAM upgrade can increase the amount of memory available to Windows and your applications.

Desktop Graphics Card Upgrades

Gaming and other graphics-intensive applications can benefit from an appropriate graphics card upgrade when the rest of the system can support it.

We can help determine whether a graphics upgrade is appropriate for your desktop and whether the system's power supply, case and other components are compatible.

Gaming Computer Repair

Gaming computers are still computers, but they can have additional hardware considerations involving graphics cards, power supplies, cooling, memory and storage.

We repair supported gaming desktops as part of our desktop computer repair service.

For customers who need an entirely new gaming computer, we also offer Custom Computer Builds.

Custom-Built Desktop Repair

We can diagnose and repair supported custom-built desktop computers, including systems assembled from individually selected components.

Depending on the problem, we can troubleshoot the system as a complete computer or test individual components to identify the source of the failure.

Windows and Software Problems

Desktop computer problems are not always caused by hardware.

Windows errors, unwanted software, malware, startup problems and other software issues can also cause computers to become slow or unstable.

Our Software & Computer Security service covers many of these problems.

Virus and Malware Removal

If your desktop computer has suspicious pop-ups, unwanted programs, browser problems or other unusual behavior, it may have a malware or security problem.

We can diagnose and address many common virus, malware and unwanted-software problems.

If you believe someone has gained unauthorized remote access to your computer, our Remote Hack & Computer Security Assistance service may be more appropriate.

Desktop Computer Tune-Ups

If your desktop is still working but has become slow, unstable or cluttered with unnecessary software, a tune-up may help.

Tune-up work can include addressing startup problems, unnecessary software, system performance issues and other software-related problems discovered during the repair process.

Tune-ups are handled as part of our general computer repair services rather than as a separate repair category.

Data Transfer and Backup

If your desktop computer is working normally and you need files transferred to another computer, drive or storage device, our Data Services can help.

If the storage device is failing or files have become inaccessible, do not treat it like a normal data transfer. Our Data Recovery service is designed for those situations.

When Your Desktop Will Not Start

If your desktop computer suddenly stops working, avoid repeatedly trying to start it if you have important data and suspect the storage device may be failing.

Depending on the symptoms, the problem could involve the power supply, motherboard, RAM, graphics hardware, storage device or software.

Our free diagnostics can help determine where the problem is located.

Repair or Replace?

A broken desktop computer does not automatically need to be replaced.

Sometimes a relatively simple component replacement or upgrade can extend the useful life of a computer. In other situations, replacement may make more sense based on the age and condition of the system.

We can diagnose the computer and explain the available options so you can decide how you want to proceed.
