Custom Computer Repair Process
Advanced Diagnostics
If the initial inspection does not reveal a clear cause, we proceed with comprehensive hardware and software diagnostics. Storage drives are tested for wear and read/write errors, RAM is stress-tested, and GPU and PSU performance are analyzed under load.
Repair Approval and Service Execution
After diagnostics, we provide a clear technical report outlining the detected issues. We explain which component is responsible and offer practical solutions — repair, replacement, or upgrade. Costs and timelines are confirmed before any work begins.
Testing and Handover
Before returning the system to the client, each custom PC undergoes mandatory load testing. We verify stability during extended stress conditions, monitor CPU and GPU temperatures, and confirm proper operation of storage devices, memory, and all connectivity interfaces.
Common Custom Computer Issues
1. Overheating and Excessive Cooling System Noise
Tap to read moreIn custom desktop PCs, especially gaming systems and professional workstations equipped with powerful CPUs and GPUs, overheating is often caused by dust buildup in radiators, dried thermal paste, or improperly.
2. SSD or Hard Drive Failure
Tap to read moreIf a custom PC fails to boot Windows, freezes during startup, or displays a “No Boot Device” message, the storage drive is often the root cause.
3. Power Supply Unit (PSU) Malfunctions
Tap to read moreA computer that does not power on, shuts down unexpectedly during gaming, or restarts under load often indicates PSU-related issues.
4. Graphics Card (GPU) Problems
Tap to read moreScreen artifacts, visual glitches, black screens, driver crashes, or game freezes are common symptoms of GPU-related issues.
5. Continuous Reboot Loop
Tap to read moreA custom PC may enter an endless reboot cycle without completing Windows startup. This behavior is often linked to unstable RAM, BIOS / UEFI misconfiguration, CPU overheating, or storage-related errors.
6. Windows Errors and Boot Issues
Tap to read moreBlue Screen of Death (BSOD), automatic repair loops, system freezes after updates, or unusually long boot times are frequent issues on custom PCs.
7. Port and Interface Failures (USB / HDMI / DisplayPort / LAN)
Tap to read moreIf the system does not recognize connected devices, displays no image output, or experiences unstable network connectivity, the issue may be caused by damaged ports or faulty motherboard controllers.
8. Liquid Damage and Component Corrosion
Tap to read moreLiquid entering the case can cause short circuits, oxidized traces, and damage to power components.

Frequently Asked Questions About Custom Computer Repair in Tallinn
When does a custom PC need diagnostics if it still powers on?
If a desktop computer built with your own components starts up but behaves нестably — slower boot times, performance drops in games or professional software, overheating, unexpected restarts, or a Blue Screen of Death (BSOD) — diagnostics should not be delayed.
What are the most common issues in custom desktop PCs?
The most frequent problems include CPU or GPU overheating, SSD (SATA / NVMe) wear, unstable power supply operation, and RAM errors. In overclocked systems, instability may result from incorrect BIOS / UEFI settings or voltage misconfiguration.
What types of repair do you perform on custom computers?
We conduct full diagnostics of all key components: motherboard, power circuits, CPU, GPU, SSD / HDD, RAM, and PSU. We replace and upgrade components, perform component-level motherboard repairs, and restore damaged ports and interfaces.
How long does custom PC repair take?
Initial diagnostics are typically completed the same day. Repair time depends on the nature of the issue and availability of specific components. In most cases, component replacement or restoration takes from one to several business days. If a rare part is required, the timeline is agreed upon in advance.
What determines the cost of custom computer repair in Tallinn?
Pricing depends on the complexity of the issue, the type of configuration, and the scope of required work. Storage replacement or preventive maintenance is generally faster and more affordable than motherboard restoration or power circuit repair.
Do you provide warranty on repairs and replaced components?
Yes, warranty coverage applies to both completed work and installed components. This includes hardware repair and software system restoration, ensuring reliable performance after service.
Can I upgrade or repair my custom PC myself?
Without proper experience and tools, there is a risk of damaging the CPU socket, motherboard traces, or GPU power components. This is especially critical in tightly packed systems or builds with liquid cooling. Professional diagnostics often prevent additional damage and unnecessary expenses.
