My computer turns on but the screen is black — what's wrong?

This is often caused by a GPU issue, display cable problem, or Windows boot failure. We connect an external monitor to differentiate between a screen issue and a system issue.

Is my data safe if my computer won't boot?

Usually yes. The hard drive is typically intact even when Windows won't boot. We attempt data recovery before any reinstallation.

Can you fix a computer that won't turn on at all?

Yes. No-power situations are usually caused by a failed power supply, blown fuse, or dead battery. We diagnose and replace the failed component.
