What to Do When Your Computer Won't Boot

It's Monday morning. You sit down, hit the power button, and... nothing. Or worse — something. A black screen with blinking cursor. A spinning wheel that never stops. A blue screen with an error you've never seen before.

Before you panic, here's a calm, practical guide to what's actually going on and what to do about it.

**Step 1: The basics (seriously, don't skip these)**
- Is it plugged in? Is the power strip on? (No judgment — we've seen it.)
- Try a different outlet.
- For laptops: is the battery completely dead? Plug it in and wait 5 minutes before trying again.
- Do a hard shutdown (hold the power button for 10 seconds) and restart.

These fix more problems than you'd think.

**Step 2: Listen and look**
Does the computer power on but nothing appears on screen? Check your monitor cable. Try a different monitor if you have one. If you hear beeping when it starts, that's a POST code — your computer is trying to tell you something specific. Write down how many beeps and call us.

**Step 3: Identify what you're seeing**
- **Spinning wheel / loading screen that never ends** — usually a software or OS issue, often fixable without data loss
- **Blue screen with error code** — take a photo of the full screen before it restarts, that code tells us exactly what happened
- **"No bootable device" or "Boot device not found"** — your hard drive may have failed or become disconnected. Stop what you're doing and call a professional immediately — continued attempts can make data recovery harder.
- **Completely dead, no lights, no sound** — could be a power supply, motherboard, or battery issue

**Step 4: Do NOT do this**
Don't keep trying to force it to boot if you suspect a hard drive issue. Don't run "fix it" software you found on Google. Don't take it to a big-box retailer where a 20-year-old will run a 2-hour diagnostic and tell you they can't recover your data.
