PC and laptop fault diagnostics in Brno
Good diagnostics saves money. Before swapping parts or reinstalling Windows, we check the most likely causes and the risk to your data. Without diagnostics a lot of technicians start swapping parts at random (“let’s try a new PSU, then new RAM, then a new board”) and the customer pays for all of it. We find out what’s actually wrong first, and only then do the work.
- Diagnostics is a paid item (from 588 CZK)
- Price upfront based on the type of fault
- We explain the result in plain terms
- A repair only proceeds with your approval
- It usually takes 30–90 minutes
- Credited against the invoice if you go ahead with the repair
Common situations
Windows crashes (BSOD)
We check the RAM (MemTest86, 4 passes), the drive (CrystalDiskInfo, SMART), the drivers (Driver Verifier) and the system logs (Event Viewer).
The drive clicks or data disappears
We minimise further writes. A bit-for-bit image first, diagnostics second. SMART, S.M.A.R.T. tools, sectors.
An unidentified problem (“something’s up with it”)
You describe what’s happening over the phone. At the workshop we go through the whole machine: CPU, RAM, GPU, PSU, drive, temperatures, Windows logs.
A slow system — hardware or software?
We check the hardware (CPU/drive/RAM tests) and the software (startup, malware, fragmentation). A recommendation based on what we find.
What we actually do
What we test — hardware
- drive SMART (HDD, SSD, NVMe)
- RAM modules (MemTest86)
- CPU stability (Prime95)
- GPU stability (FurMark)
- power supply (OCCT PSU)
- component temperatures
- motherboard (visual + multimeter)
- laptop keyboard and display
What we test — software
- Windows Event Viewer logs
- Reliability Monitor
- malware check
- startup items
- installed programs and driver conflicts
- BIOS version and updates
- Windows Update status
The outcome may be
- the repair pays off — a specific part
- an SSD or RAM upgrade is enough
- a data backup first (drive at risk)
- a Windows reinstall will help
- the repair doesn’t pay off — we recommend a new one
- just cleaning and a repaste
- virus removal + protection setup
Indicative prices
What it usually costs
Prices are indicative — we confirm the final price in writing after diagnostics and proceed with the repair only after your approval. Diagnostics is a paid item.

| Service work — per started half hour | 598 CZK |
Why Servis PC Brno
Diagnostics isn’t free
It’s paid technician work (30–90 min). The only free service is the first rough assessment for HDD data recovery. We say so upfront — we don’t advertise “free” and then charge in secret.
Our equipment
CrystalDiskInfo, MemTest86, Prime95, FurMark, OCCT, HWMonitor, a Fluke multimeter, an external USB-SATA dock for testing drives outside the computer.
A defined procedure, not guesswork
A step-by-step checklist from the most likely cause. We identify most faults within the first hour.
A written evaluation
You get a report with the specific measured values (temperatures, SMART values, load) and a recommendation. You can come back to it any time.
What is included
- A visual hardware check
- Testing of the drive, RAM, CPU, GPU, PSU and temperatures
- A check of Windows logs and malware
- A written report with the cause and a recommendation
- A repair quote
- Advice on future prevention
Warranty & claims
Claims are handled individually under Czech law. If the same fault returns within a short time, we look at it together and agree on the next steps. New parts carry the standard manufacturer warranty (typically 12–24 months, depending on the component).

Who this service is for
People whose computer has an unidentified problem — it shuts off, crashes, is slow or makes odd noises. Diagnostics is the right first step, instead of swapping parts at random.
Frequently asked questions
Why do you charge for diagnostics? +
Because the technician spends time (30–90 minutes) measuring and evaluating the fault. Without diagnostics a repair would be guesswork and you’d pay for swapping parts that aren’t faulty. Diagnostics is an investment that pays off.
Is the diagnostics credited against the repair? +
Yes. If you go ahead with the repair with us after diagnostics, we credit the amount against the invoice. If you decline the repair (for example, too expensive on an old machine), you only pay for the diagnostics.
How long does diagnostics take? +
A standard one is 30–90 minutes. In-depth diagnostics of non-reproducible faults (occasional BSODs, occasional shutdowns) can take 4+ hours (it needs monitoring under load).
What if diagnostics shows no fault? +
Even “no fault” is a result — at the very least we tell you the problem is probably in the software (a reinstall, malware, drivers) or in how it’s used. In that case the diagnostics fee applies, but you save yourself a pointless hardware swap.
Can you come to my home? +
Yes, on-site visits across Brno (rate 698 CZK + diagnostics 588 CZK). For drive faults we recommend bringing it to the workshop — we have professional analysis equipment there.
What expertise do you have? +
In IT since 2008 (ITHOPE s.r.o.), thousands of diagnostic jobs. CrystalDiskInfo, MemTest86, Prime95, FurMark, OCCT, a Fluke multimeter. Specialists in Windows and Lenovo/HP/Dell/Asus.
