Desktop Computer & PC Repair in Beylikdüzü
At our Paradise AVM service point, we provide professional solutions for desktop computers, custom gaming PCs, workstations and office systems, including POST startup faults, Debug LED diagnosis, PSU power-rail fluctuations, bent CPU socket pins and component replacement.
Desktop Hardware Diagnosis & Power Sequencing Protocol
Instead of replacing parts by trial and error, we verify power rails, POST startup signals and Debug LED codes through measurements and microscopic inspection.
1. Power & PSU 12V Voltage Analysis
We measure ripple on the PSU's 12V, 5V and 3.3V rails and standby voltages on the ATX 24-pin connector.
2. POST & Debug LED Monitoring
Startup failures that stop at the CPU, DRAM, VGA or BOOT LED are isolated using an external oscilloscope and buzzer.
3. CPU Socket Pin Restoration
Bent pins in Intel LGA and AMD AM5 sockets are straightened under a microscope to restore memory-channel operation.
4. VRM MOSFET & Power Stage Checks
Shorted MOSFETs, PWM drivers and faulty inductors in CPU and memory power stages are repaired at component level.
5. PCIe Bus & GPU Testing
PCIe slot damage caused by heavy graphics-card sag and VRAM bit errors are checked with MATS/MODS.
6. Stability Verification Under Load
After repair, we check voltage drops and stability under full load using FurMark, Cinebench and MemTest86.

Desktop Fault Diagnosis by Symptom
The same desktop PC symptom may originate from the PSU, graphics card or memory. Our initial testing procedures:
Gaming PCs & High-Performance Custom Systems
We address hardware bottlenecks and prevent thermal throttling to improve stability in gaming, 3D modelling and demanding workloads.
Custom Rig Assembly
We assemble your online-purchased parts in an anti-static environment with professional cable routing, optimised fan direction and careful installation.
Graphics Card & Bottleneck Analysis
We balance CPU and GPU performance, address PCIe bandwidth losses and improve stability.
Workstation & Rendering Stability
We test ECC memory, NVMe RAID and VRM cooling to prevent crashes during rendering workloads that run for hours.
Desktop Computer Repair FAQ
What is checked first if a desktop PC will not turn on?
After the outlet and power cable, we check the PSU switch, case power button, ATX/EPS power connectors including the 24-pin supply, and motherboard short circuits. We do not decide to replace a component without taking measurements.
The PC runs but there is no display. Is the graphics card faulty?
The graphics card is only one possibility. Poor RAM contact, corrupted BIOS firmware, bent CPU socket pins, PCIe slot damage or inadequate PSU power can cause the same symptom. POST fault-isolation testing is essential.
Can you assemble a PC using parts I buy online?
Yes. Before assembly, we check CPU-to-motherboard socket compatibility, RAM frequencies, PSU capacity and liquid-cooling radiator placement. We assemble the system with professional cable routing and update the BIOS before returning it.
Will my data be deleted during desktop PC servicing?
Your files are not deleted during hardware, PSU and motherboard checks. If formatting or resetting Windows is needed, we obtain your approval before starting.
Should I bring a monitor or cables with my desktop PC?
No. Our laboratory has test monitors and power cables. Bringing your PC case is sufficient; you may also bring any special adapter or external component you use.
How is the price of desktop computer repair determined?
For an initial assessment, share the motherboard, CPU, graphics card, RAM and PSU details, the fault symptoms and any previous work. PSU replacement, socket pin repair and component-level motherboard work have different scopes. A technical inspection is required to determine the work and final price. Confirm any diagnostic charge and the proposed work when handing in the device.
What affects the turnaround time for a desktop PC?
Whether the fault is constant or intermittent, the availability of required parts and post-repair tests can affect timing. Starting successfully alone does not prove that a shutdown or display problem under load has been resolved. After inspection, ask for an estimated return time, whether parts must be ordered and which final checks will be performed.
Which hardware and fault details should I share before visiting?
If known, provide the motherboard, CPU, graphics card, RAM and PSU models, and describe symptoms such as no response, no display, shutdown during games or error messages. State when the problem began, any newly installed parts and any settings you changed. If you cannot find the model, share a photo of an existing label or error message instead of forcing parts out.
