- PC won't turn on tickets are usually a dead PSU, loose power cables, or an unseated motherboard connector.
- Always run the diagnostic tool first — it points you to the failing component before you unscrew anything.
- Work only at the workbench; PCs placed on counters can't be disassembled.
- Screws and cables must be fully seated before a part registers as installed.
- Finish every repair with a passing benchmark — no power-on means no payout.
Why a PC Won't Turn On in Fix PCs
A "no power" ticket is one of the most common orders in Fix PCs, DEVTEC STUDIOS' Roblox PC repair simulator. Before you touch a screwdriver, understand the three root causes the game uses for dead machines: power supply failure, disconnected cables, and components that were removed and never reseated properly.
| Symptom | Likely Cause | Difficulty | Payout Trend |
|---|---|---|---|
| PC completely dead, no fans | Dead PSU | Easy | Low-Mid |
| PC dead after transport | Loose 24-pin / PSU cable | Easy | Low |
| PC powers on but fails benchmark | Wrong or weak part installed | Medium | Mid |
| PC dead with missing screws noted | Part not fully reseated | Easy | Mid |
| PC dead + upgrade requested | Dead PSU + new GPU/CPU order | Hard | High |
Never guess. Run the diagnostic tool on the customer's PC before opening the case — the scan identifies the failing component and saves you from swapping parts that were never broken.
Step-by-Step: Fixing a Dead PC
This is the full repair loop for a no-power ticket, from accepting the order to collecting your Cash. Follow it in order — skipping the diagnostic step is the number-one way to waste parts and time.
Accept the order and locate the PC
Interact with the waiting customer or order counter to take the repair ticket, then head to the shelf or counter where that PC is placed.
Run the diagnostic scan
Use the diagnostic tool on the PC. For no-power symptoms, expect the scan to flag the PSU, a detached power cable, or an unseated motherboard connector.
Carry the PC to the workbench
Pick the PC up (E to interact) and place it on your workbench. Disassembly and part swaps only work at the bench.
Open the case and check power connections
Unscrew the side panel with your screwdriver. Click each cable connector and pull in the indicated direction to detach it. Confirm whether the PSU cable to the motherboard is connected at all.
Replace or reseat the faulty part
If the PSU is dead, unscrew it and install a replacement from your inventory with enough wattage for the build. If the cable was simply loose, reseat it fully.
Close up, plug in, and benchmark
Reattach the side panel, connect the PC to power, and power it on. Run the benchmark — a passing score confirms the repair.
Deliver and get paid
Return the PC to the customer to collect Cash and XP, then restock whatever part you used so the next no-power order doesn't stall.
If the PC won't power on after your repair, confirm the PSU is connected to the motherboard and the power switch on the PSU itself is flipped — this catches more stuck tickets than any other check.
Common No-Power Causes and Fixes
Each dead-PC scenario has a different fix and a different margin. Use this reference to pick orders worth your time and parts stock.
| Cause | How to Identify | Fix | Parts Needed | Margin |
|---|---|---|---|---|
| Loose power cable | Diagnostic flags cable | Reseat connector | None | High |
| Dead basic PSU | Scan points to PSU | Swap in 500W+ PSU | 500W Basic PSU ($50) | Good |
| Low-wattage PSU + high-end GPU | PC dead after upgrade order | Install higher-wattage PSU | 650W-1000W PSU | Great |
| Unseated part | Screws missing on ticket | Unscrew, reseat, re-screw | None | High |
| Combo: PSU + part upgrade | Ticket lists two tasks | Full swap + benchmark | PSU + GPU/CPU | Best |
Quick Fix Orders
- Loose cables, reseated parts
- No parts cost
- Fast turnover for early Cash
Standard PSU Swap
- Dead 500W-class PSU
- Cheap part, solid margin
- Great steady income
Upgrade Tickets
- PSU + flagship GPU/CPU
- Highest payouts
- Needs deep inventory
Installing a low-wattage power supply in a build with high-end parts can fail the benchmark even when everything is connected. Match PSU wattage to the build tier before you close the case.
Troubleshooting Checklist for Stuck Repairs
When a no-power repair refuses to finish, work down this checklist before abandoning the ticket. Nearly every stuck job comes down to one of these five oversights.
Before You Re-Open the Case:
- Diagnostic scan run and failing part identified
- PSU connected to motherboard and power switch flipped
- All screws removed before pulling the part
- Replacement part fully screwed in and cables reconnected
- Side panel reattached and benchmark passed
If a component refuses to detach, there's almost always a remaining screw or an attached power cable. Click around the part — don't force the swap.
Making Money From Dead-PC Orders
No-power tickets are the backbone of a profitable shop because they scale with your inventory. Early on, take simple loose-cable fixes to build Cash; as you unlock better parts, filter toward PSU-plus-upgrade orders for the biggest payouts.
| Stage | Best Orders | Priority Upgrade | Why |
|---|---|---|---|
| Level 1-5 | Cable reseats, basic PSU swaps | Better screwdriver | Cuts minutes off every job |
| Level 6-15 | Mid-tier builds, 650W PSUs | Second workbench | Two PCs at once |
| Level 16-25 | Flagship GPU/CPU upgrades | Shelving + stock depth | More simultaneous orders |
| Level 25+ | Endgame full builds | Flagship parts ($1,500 GPU) | Top benchmark ratings |
Keep a balanced inventory of high-demand components — PSUs, GPUs, and RAM — instead of hoarding niche parts. Running out of a common PSU mid-order kills your momentum and your hourly income.
FAQ
Q: Why won't the customer's PC turn on after I replaced the PSU?
Check that the PSU is connected to the motherboard and the power switch on the PSU unit is flipped. Also confirm every cable you unplugged was reconnected — a single detached connector keeps the build from powering on.
Q: How do I fix a PC that won't turn on if I can't remove the part?
A part that won't detach almost always has a remaining screw or an attached power cable. Unscrew every fastener on the component and unplug its connector before pulling it out.
Q: Do I need a specific PSU tier for high-end builds?
Yes. Low-wattage power supplies can fail the benchmark when paired with flagship parts. Use a 650W or higher PSU for mid-tier builds and a 1000W-class unit for endgame configurations.
Q: What's the fastest way to earn Cash from no-power orders early?
Take loose-cable and reseat fixes first — they cost no parts and complete in minutes. Reinvest that Cash into a better screwdriver and a second workbench, then move up to PSU swaps and upgrade tickets.
