When your computer stops working properly, productivity and daily routines are disrupted. ErlenTek provides professional computer repair services for homeowners and small businesses throughout Auburn and South King County, including Kent, Covington, Maple Valley, and Enumclaw.

Desktop computer repair and diagnostics by ErlenTek in Auburn, Washington

We service desktops, laptops, custom-built systems, and business workstations. Every repair begins with structured evaluation to identify the underlying issue rather than applying temporary fixes. If you are not sure what is wrong yet, our computer diagnostics and troubleshooting service is often the best starting point for unstable, slow, or unpredictable systems.

Common Computer Problems We Diagnose

  • Slow or freezing systems
  • Startup failures and boot errors
  • Hardware faults and failing components
  • Overheating and thermal shutdowns
  • Software conflicts and driver issues
  • System instability and random crashes
  • Bad or failing motherboard
  • Blue screen errors (BSOD)
  • Failed BIOS flash
  • Unresponsive applications

If your computer is unstable, making unusual noises, or failing to start properly, we isolate the cause through hardware testing and system evaluation before recommending repair, upgrade, or replacement. In some cases, performance problems can be resolved more cost-effectively through our computer upgrades and SSD upgrades service rather than full replacement.

Desktop and Laptop Repair

We repair both desktops and laptops, including custom-built PCs and business workstations. We work with multiple OSes, such as Windows 10, Windows 11, Windows Server, macOS, and various versions of Linux (Ubuntu, RedHat, Mint, etc). Services may include storage replacement, memory upgrades, motherboard diagnostics, power supply replacement, cooling system repair, operating system restoration, and general hardware or software troubleshooting.

If you need a more device-specific page, you can also visit our PC repair page for desktop systems or our laptop repair page for portable systems with charging issues, overheating, startup failures, or display-related concerns.

For customers experiencing suspicious pop-ups, fake virus alerts, or infection-related performance issues, our virus and malware removal service helps ensure systems are cleaned properly before additional optimization begins. If the issue involved a fake support warning, browser lock page, or unauthorized remote access, our scam remediation service may be more appropriate.

Hardware Diagnostics and Component Testing

Accurate diagnostics are critical when a computer is crashing, unstable, or showing signs of failing hardware. We test and verify individual components to identify the actual cause of the problem before recommending next steps.

  • Hard drives and solid-state drives (SSD)
  • Memory (RAM)
  • Power supplies
  • Cooling systems and thermal performance
  • Motherboards
  • Graphics cards (GPU)

Computer diagnostic tools including multimeter and testing equipment used by ErlenTek

Each system is tested after repair to help ensure long-term stability before it is returned. If important files are at risk because of drive failure or storage corruption, visit our data recovery services page for more information.

Performance Optimization and System Cleanup

If your computer has slowed over time, we remove unnecessary startup programs, correct system issues, update drivers, verify disk health, and optimize configuration where appropriate. When a hardware bottleneck is involved, we may recommend targeted improvements such as SSD installation or memory expansion to significantly improve responsiveness and extend the useful life of the system.

For customers setting up a replacement system instead of repairing an older one, we also offer installation and new computer setup. If you want a purpose-built replacement rather than continuing to repair an aging machine, visit our custom PC builds page.

On-Site, In-Office, and Remote Support

Depending on the issue, service can be performed on-site, remotely, or at our Auburn office. Some repairs require bench diagnostics and component testing, while many software-related issues can be handled remotely for faster turnaround. If your issue can likely be resolved without bringing the system in, see our remote support page.

We provide free diagnostics in our Auburn office and will quote a price before any work is completed (unless work is approved when the computer is dropped off).

For office environments and multi-user systems, broader service may fall under our business IT services or IT consulting pages.

Frequently Asked Questions

How long does computer repair typically take?

Many software-related problems can be resolved the same day. Hardware repairs vary depending on part availability, system condition, and the complexity of the issue.

Is it worth repairing an older computer?

In most cases, upgrading storage or memory can significantly extend the life of a system. We provide honest recommendations based on system condition, performance needs, and cost-effectiveness.

Do you work on custom-built PCs?

Yes. We build, service, and troubleshoot custom-built desktops, including gaming systems and performance workstations. We also offer custom PC builds if replacement is the better long-term solution.

Can you recover files if my computer won’t turn on?

If the storage device is still functional, files can often be recovered. See our data recovery services page for more information.
