About FullTestPC

FullTestPC is a free online testing service for checking computers, laptops, monitors and other devices.

We build simple tools that help you quickly test tech right in the browser. No need to install programs or figure out complex settings. Open the test you need, check the device and see the result immediately.

New tools for testing various devices and their components keep appearing on FullTestPC. We regularly expand functionality and improve existing tests to make tech checking even more convenient and accurate.

FullTestPC is a project by TechSell.by, where you can find tested used PCs, laptops and monitors. Every device is tested before sale.

What you can test on FullTestPC

Keyboard test

Online keyboard check: all keys, modifiers, sticking and missed presses.

Monitor test

Monitor test for dead pixels, backlight bleed, gradients, color accuracy and ghosting.

Mouse / trackpad test

Buttons, cursor, scroll and gestures - check them in the browser.

CPU test

Compute speed, memory throughput and multi-threading right in the browser.

GPU test

Check GPU stability and performance under graphics and compute load.

Step-by-step checklists

For each device we have three levels of diagnostics: quick check (5–10 minutes, no software), medium check (15–20 minutes, built-in Windows tools) and full check (30–60 minutes, specialised utilities like AIDA64, FurMark, CrystalDiskInfo, Victoria and OCCT).

How our tests work

All tests run right in your browser using JavaScript, WebGL and WebGPU. No downloads, no installs, no sign-up. Results are relative — they help you spot performance drops, instability and obvious defects, but cannot replace specialised desktop benchmarks. For full diagnostics we recommend using Cinebench, 3DMark, OCCT, HWiNFO64 and other tools alongside our tests.

Who is this for?

Buying used tech

Open FullTestPC on the device you are about to buy and run the tests right at the seller's place.

Diagnosing your own PC

If your computer started lagging or you suspect overheating, run our tests to check CPU and GPU stability.

Before selling

Run all tests and show the results to the buyer — this builds trust and speeds up the deal.

Methodology and what we measure

What browser tests show

  • CPU compute speed under different workloads
  • GPU FPS and compute performance
  • Performance drops during sustained load
  • Artifacts, freezes and instability
  • Dead pixels, backlight bleed, stuck keys

What browser tests cannot show

  • CPU and GPU core temperatures
  • Current frequencies and voltage
  • Power draw (watts)
  • Full VRAM testing
  • Exact benchmark scores comparable to Cinebench or 3DMark

Recommended programs for full diagnostics

  • Cinebench R23 / 2024 — CPU single/multi-thread performance
  • 3DMark / Unigine Superposition — gaming GPU performance
  • OCCT / FurMark / Prime95 — stability and cooling stress test
  • HWiNFO64 / HWMonitor — temperatures, frequencies, voltage
  • CrystalDiskInfo / Victoria — SSD and HDD health
  • GPU-Z / MSI Afterburner — GPU parameters and monitoring
