What Hardware Computer Diagnostics Includes
The service covers in-depth verification of core hardware elements:
- Power Supply Unit – voltage measurements under load, ripple check, stability on 3.3V/5V/12V rails, real power output test
- RAM – full module testing (MemTest86+ cycles), individual slot verification, ECC/non-ECC error detection
- Motherboard – POST code analysis, VRM phase inspection, capacitors, CPU socket, chipset, audio/network controllers
- CPU – temperature monitoring, stability under heavy load, degradation check
- Graphics Card – artifact testing (FurMark, OCCT 3D), GPU/memory power delivery, chip temperatures
- Storage Drives – SMART parameter readout, surface scanning (Victoria, HD Tune), SATA/power cable checks
- Cooling System – heatsink/thermal paste condition, fan/pump operation, load temperatures
- Interfaces – USB port testing (speeds included), SATA/M.2 slots, audio, network card
- Visual Inspection – swollen capacitors, corrosion, dust buildup, overheating marks, physical damage
Clients receive a detailed report with photos of issues and clear repair recommendations.
When Hardware Computer Diagnostics Is Needed
Common indicators requiring hardware-level checking:
- PC shows no response to power button or powers on without BIOS/screen
- BIOS beep codes (various patterns) or POST card error codes
- Sudden shutdowns/reboots without BSOD, especially under load
- Screen artifacts, black screen after OS/games launch, flickering
- System detects only partial RAM or misses modules entirely
- Frequent BSODs with codes like MEMORY_MANAGEMENT, IRQL_NOT_LESS_OR_EQUAL
- Fans spin but monitor displays "no signal"
- Excessive component heat, burning smell, unusual noises from PSU/HDD
- Peripheral issues after cleaning/replacement (USB, network, audio failure)
- System boots but remains unstable even after clean OS reinstall
Hardware diagnostics confirms or rules out component-level causes and prevents unnecessary expenses.
Stages of Hardware Computer Diagnostics at Grade
- Detailed symptom collection: exact behavior, onset timing, power surges, cleaning, drops, new hardware additions
- Visual inspection of case, motherboard, PSU, GPU for visible defects
- PSU testing: connection to load tester, voltage/ripple measurements
- Minimal configuration boot outside case (motherboard + CPU + 1 RAM stick + PSU + video output)
- POST process analysis: BIOS signals/codes, testing with known-good parts
- Sequential RAM testing: one stick at a time, different slots, extended cycles
- Drive verification: connection to alternate PC, SMART read, surface scan, cable checks
- Graphics card testing in another system or via integrated graphics
- Full system stress load: temperature/voltage monitoring, stability checks (AIDA64, Prime95, FurMark)
- Report preparation: photos of problem areas, test logs, conclusions, repair plan
