- How to repair a PC in Fix PCs follows a 7-step loop: order, diagnose, bench, swap, test, deliver.
- Diagnosis first: always scan the PC to identify the failing part before opening the case.
- Benchmark tests confirm your repair — a failure usually means loose cables or screws.
- Workbench is mandatory: PCs can only be disassembled at a bench, not on counters.
- Reinvest early Cash into better tools and a second workbench for faster turnover.
How to Repair a PC: The Core Loop
Repairing computers is the heart of Fix PCs by DEVTEC STUDIOS. Every job follows the same structure: accept a customer's broken machine, find out what's wrong, physically fix it at your workbench, and prove the fix with a benchmark before collecting payment. Mastering this loop is what separates a slow starter from a profitable shop.
Video Highlights:
- The full repair loop from ticket to payment
- Screw and cable interaction mechanics
- Benchmark pass/fail conditions
Note: no official Fix PCs tutorial videos are currently verified, so this guide is based on in-game mechanics from the official game page.
Never start unscrewing before you diagnose. A scan takes seconds; replacing the wrong part wastes both the part and your time.
Here is how the main repair stages compare in difficulty and payoff:
| Stage | Difficulty | Time Cost | Payout Impact |
|---|---|---|---|
| Accept order | ★ | Very low | Sets your reward ceiling |
| Diagnose fault | ★★ | Low | Determines correct fix |
| Workbench teardown | ★★★ | Medium | Errors force rework |
| Part installation | ★★★ | Medium | Wrong part = redo job |
| Benchmark test | ★★ | Low | Gate for payment |
| Delivery | ★ | Very low | Collects Cash |
Step-by-Step Repair Walkthrough
Accept a customer order
Walk up to a waiting customer or the order counter and interact to accept a repair ticket. Each ticket identifies which PC needs work — head to the shelf or counter where that machine sits.
Diagnose the fault
Use the diagnostic tool on the customer's PC. The scan points you to the failing component: a dead GPU, faulty RAM, a failing PSU, or sometimes just loose cables.
Bring the PC to the workbench
Carry the PC to your workbench and place it down. Disassembly and part swaps only happen at the bench — you cannot work on a PC sitting on a random counter.
Open the case and remove the broken part
Unscrew the side panel with your screwdriver, then unscrew the faulty component from its slot. Keep track of screws, since some jobs require reusing them when reseating parts.
Install the replacement part
Take the correct replacement from your parts inventory, screw it firmly into place, and reconnect any power or data cables that were detached.
Close up and run the benchmark
Reattach the side panel, plug the PC in, and power it on. Run the benchmark to verify the repair. A passing score confirms the fix; a failure means something is still loose or wrong.
Deliver the PC and get paid
Return the repaired PC to the customer to collect your Cash. Take simple orders first — loose cables and single-part swaps — to build capital early.
If the benchmark fails after a part swap, check three things in order: cable connections, fully seated screws, and PSU wattage. Low-wattage power supplies fail benchmarks with high-end parts installed.
Diagnosis: Matching Symptoms to Faulty Parts
Fast diagnosis is the biggest speed lever in your shop. Instead of scanning blindly, learn the common fault patterns so a single scan confirms what you already suspect.
| Symptom | Likely Fault | Typical Fix | Difficulty |
|---|---|---|---|
| PC won't power on | PSU unplugged or dead | Reseat/replace PSU, check switch | ★ |
| No display output | Dead GPU | Swap GPU | ★★ |
| Random crashes | Faulty RAM | Reseat or replace RAM stick | ★★ |
| Slow boot times | Aging HDD | Swap to SSD | ★ |
| Overheating instability | Cooler failure | Replace cooler | ★★ |
| Nothing obviously wrong | Loose cables | Reconnect all cables | ★ |
Loose Cable Jobs
- Fastest ticket type
- No parts cost
- Ideal first orders for new shops
Single-Part Swaps
- Standard mid-game work
- One component replaced
- Good margin on RAM and storage
Premium Builds
- Highest payouts
- Flagship GPU/CPU installs
- Requires strong stock and cash
Keep your most-used parts within arm's reach of the workbench and batch similar orders together. Faster diagnosis and reassembly means more completed repairs per hour.
Workbench Mechanics: Screws, Cables, and Controls
The physical repair interactions are where new players lose the most time. Each screw must be individually removed by holding left-click and following the on-screen twist motion, and cables must be unplugged by pulling in the indicated direction. Reassembly is the reverse — nothing registers as installed until screws and cables are fully seated.
| Input | Action |
|---|---|
| WASD / Mouse | Move and look |
| Left-click | Interact, pick up parts, unscrew |
| E | Talk to NPCs, place items on bench |
| Tab | Open parts inventory |
| Q | Drop held item |
| Scroll / Number keys | Cycle tools (screwdriver) |
If a component refuses to detach, check for remaining screws or an attached power cable. Almost every "stuck part" issue is an overlooked screw or PSU connector.
Common repair errors and fixes:
| Problem | Cause | Solution |
|---|---|---|
| Part won't detach | Hidden screw or cable | Inspect all screws and connectors |
| PC won't power on | PSU unplugged / switch off | Connect PSU to motherboard, flip switch |
| Ticket won't complete | Wrong part tier installed | Compare installed parts to ticket requirements |
| Benchmark fails | Loose cable or low PSU wattage | Reseat cables, upgrade PSU |
Repair Shop Upgrades: What to Buy First
Every completed repair feeds your Cash, and where you spend it determines your hourly income. Follow a consistent upgrade order rather than buying whatever catches your eye.
| Priority | Upgrade | Why It Matters |
|---|---|---|
| 1 | Better tools | Faster screwing, unplugging, diagnosing on every order |
| 2 | Second workbench | Work on two PCs simultaneously |
| 3 | Shelving expansion | Store more parts, take more orders at once |
| 4 | High-demand stock | GPUs, RAM, PSUs for the most common tickets |
| 5 | Premium parts | Unlock flagship GPU/CPU orders with top payouts |
Keep a balanced stock of high-demand components instead of hoarding niche parts. Running out of a common part mid-order kills your momentum — restock top sellers first.
Shop Milestones:
- Complete 10 loose-cable or single-part orders
- Buy upgraded tools before anything else
- Add a second workbench
- Stock GPUs, RAM, and PSUs consistently
- Complete a flagship-tier build order
Repair FAQ
Q: How do I repair a PC in Fix PCs?
Accept a customer order, run the diagnostic tool to find the failing part, carry the PC to your workbench, unscrew and remove the broken component, install the replacement, reconnect cables, run the benchmark, and return the PC to the customer for payment.
Q: Why won't my repaired PC pass the benchmark?
A failed benchmark almost always means something is loose or incompatible. Check that all screws are fully seated, cables are reconnected, and the PSU has enough wattage — low-wattage power supplies fail benchmarks with high-end parts installed.
Q: Can I repair a PC anywhere other than the workbench?
No. Disassembly and part swaps only work at the workbench. If you cannot open a customer's PC, carry it to your bench and place it down first.
Q: What are the best starter repair orders?
Take loose-cable fixes and single-part swaps first. They cost little or nothing in parts, complete fast, and build the Cash you need for better tools and a second workbench.
