- How to screw and plug cables in Fix PCs: hold left-click on each screw and follow the on-screen twisting motion.
- Cables unplug directionally: click the connector and pull in the indicated direction.
- Parts won't register as installed until screws and cables are fully seated.
- PC won't power on? Check the PSU-to-motherboard connection and the PSU power switch.
- Better tools speed up every screw and cable interaction — an early-game must-buy.
Screw and Cable Mechanics Overview
Fix PCs is DEVTEC STUDIOS' Roblox PC repair simulator, and the workbench is where most of your playtime happens. Beyond diagnosing faults and picking replacement parts, every repair stands or falls on two physical interactions: unscrewing and re-screwing components, and unplugging and re-seating cables. If either step is done halfway, the part will not register as installed and the benchmark test will fail — costing you time and payout.
These mechanics reward precision over speed, but once you internalize the interaction patterns, you can complete jobs far faster.
| Interaction | How to Perform | Common Use Case |
|---|---|---|
| Unscrew a part | Hold left-click on each screw, follow the twist motion | Removing GPU, PSU, side panel |
| Screw in a part | Hold left-click, follow reverse twist motion | Installing replacement components |
| Unplug a cable | Click connector, pull in indicated direction | PSU cables, front-panel connectors |
| Plug a cable | Click port, push until fully seated | Reassembly and power-up |
Screws and cables are the number one reason new players fail benchmark tests. A part that looks installed but isn't fully screwed or connected will not count — always finish every screw and cable before closing the case.
Step-by-Step: Unscrew, Swap, and Replug a Component
Follow this sequence at the workbench for nearly any part replacement job. The same loop applies whether you're swapping a dead GPU, a faulty PSU, or reseating loose RAM.
Place the PC on the workbench
Carry the customer's PC from the shelf to your workbench and interact to set it down. You cannot disassemble a PC sitting on a random counter — the build view only opens at the bench.
Unscrew the side panel
Hold left-click on each panel screw and follow the on-screen motion to twist them out. Keep track of your screws — some jobs require reusing them when reseating parts.
Unplug attached cables
Before removing a part like a PSU or GPU, click each attached power or data connector and pull in the indicated direction. Skipping this step blocks the part from detaching.
Unscrew and remove the faulty part
Twist out the screws holding the broken component, then remove it from its slot.
Install the replacement and reconnect
Slot in the correct replacement from your inventory, screw it firmly into place, and reconnect every cable you detached — fully seated, not just touching the port.
Close up and run the benchmark
Reattach the side panel, plug the PC in, and power it on. Run the benchmark to verify: a passing score confirms the fix, a failure means something is still loose.
Removing screws is not enough — cables block part removal too. If a part won't come out, check for a remaining screw or an attached power cable before assuming the game is bugged.
Cable Types and Connections to Check
Different components in Fix PCs require different cable attention. Knowing which connections matter saves you from failed benchmarks and repeat trips to the build view.
PSU Cables
- Main power line: PSU to motherboard, must be fully seated
- Power switch: flip the PSU switch before power-on
- Most common cause of a dead PC
Front-Panel Connectors
- Unplug by clicking and pulling the indicated direction
- Required before certain case or board work
- Reseat fully during reassembly
Data and Power to Parts
- Some parts carry their own connectors
- Detach before unscrewing the part
- Reconnect after installing the replacement
| Symptom | Likely Cable Cause | Fix |
|---|---|---|
| PC won't power on | PSU not connected to motherboard | Reseat PSU cable, flip PSU switch |
| Part won't detach | Power cable still attached | Unplug connector, then unscrew |
| Part shows not installed | Cable not fully seated | Push connector until it clicks |
| Benchmark fails | Any loose screw or cable | Reopen build view, check all connections |
Run the diagnostic tool before opening the case. The scan points you to the failing component — sometimes the whole problem is just a loose cable, which is the fastest and cheapest repair ticket in the game.
Speed Tips: Screw and Plug Faster
Speed is money in your repair shop. Every second saved per screw and cable compounds across dozens of orders per hour.
- Upgrade your screwdriver early. Better tools speed up screwing, unplugging, and diagnosing — one of the best early-game investments, cutting minutes off every order.
- Memorize fault patterns. Recognizing which symptoms point to which parts reduces diagnostic time and unnecessary disassembly.
- Keep top sellers near the bench. Stock high-demand parts (GPUs, RAM, PSUs) within arm's reach so you're not walking back and forth mid-job.
- Batch similar orders. Working consecutive jobs with similar faults means fewer tool swaps and faster muscle memory on the screw motion.
- Finish screws completely. Half-turned screws force you to reopen the build view — slower than doing it right the first time.
Tools first, then a second workbench, then shelving. Upgraded tools speed up every single screw and cable interaction you'll ever perform, while a second bench lets you run two PCs simultaneously.
Troubleshooting Checklist
Before returning any PC to a customer, run through this checklist. Each item is a common failure point that costs payouts if missed.
Pre-Delivery Checklist:
- Every screw fully twisted in — none loose or missing
- All power and data cables fully seated
- PSU connected to motherboard and switch flipped on
- Side panel reattached securely
- Benchmark test passed with a confirmed score
| Sticking Point | Solution |
|---|---|
| Part won't come out | Check remaining screws or an attached power cable |
| PC won't power on | Confirm PSU-motherboard connection and PSU switch |
| Ticket won't complete | Compare installed parts against ticket requirements; some jobs need a specific part tier |
| No money for parts | Do small diagnostic jobs first or sell spare removed parts |
FAQ
Q: How do I screw in a part in Fix PCs?
Hold left-click on each screw and follow the on-screen motion to twist it in. The part only registers as installed once every screw is fully tightened — partial screws don't count.
Q: Why won't my part come out after unscrewing it?
Check for an attached power or data cable. Cables must be unplugged by clicking the connector and pulling in the indicated direction before the part can detach.
Q: My PC won't turn on after reassembly. What's wrong?
Confirm the PSU is connected to the motherboard and the power switch on the PSU itself is flipped. Also verify every cable is fully seated, not just touching the port.
Q: How to screw and plug cables faster in Fix PCs?
Upgrade your screwdriver and diagnostic tools early — better tools speed up every screw and cable interaction. Batching similar orders and keeping common parts near the workbench also raises your repairs per hour.
