Desktop computer repair in Mumbai covers a wide range of faults — from a dead power supply (₹1,499–₹3,999 to replace) to chip-level motherboard repair (₹3,999–₹9,999). Unlike laptops, desktops are highly modular: individual components (PSU, RAM, GPU, storage) can be replaced without touching the motherboard, often making repairs cheaper than equivalent laptop fixes.
Common Desktop Computer Problems — Cost Table
| Problem | Likely Cause | Repair Cost | Time |
|---|---|---|---|
| Computer won't turn on | Dead PSU or power button fault | ₹499 – ₹3,999 | Same day |
| No display / black screen | RAM, GPU, or monitor fault | ₹499 – ₹4,999 | Same day |
| Very slow performance | HDD or insufficient RAM | ₹1,999 – ₹4,999 | Same day |
| Overheating / auto-shutdown | CPU fan failure, dust buildup | ₹499 – ₹1,499 | Same day |
| Beeping on startup | RAM, GPU, or hardware POST error | ₹499 – ₹3,999 | Same day |
| GPU / graphics fault | Dedicated GPU failure | ₹2,499 – ₹7,999 | 1–2 days |
| Virus / ransomware | Malware infection | ₹799 – ₹1,999 | Same day |
| Windows not booting | OS corruption or SSD failure | ₹999 – ₹2,999 | Same day |
| Motherboard chip-level repair | Power surge, liquid damage | ₹3,999 – ₹9,999 | 2–4 days |
Desktop Not Turning On — Step-by-Step Diagnosis
- Check the power cable and wall socket — try the socket with another device. Check the voltage switch on the back of the PSU (should be 230V in India).
- Check the power LED on the case — does it flash when you press power? A flash but no boot suggests a hardware fault (RAM, CPU, or GPU). No LED at all suggests PSU or power button fault.
- Reseat RAM sticks — remove, clean contacts with eraser, reinsert firmly. 30% of "dead" desktops boot after this.
- Disconnect peripherals — remove all USB devices, external drives, extra monitors. Try booting with just keyboard + one monitor.
- Test with a known-good PSU — if available, swap PSUs to confirm whether the PSU is dead.
Desktop vs All-in-One Repair — Key Differences
| Tower Desktop | All-in-One (AIO) | |
|---|---|---|
| Repairability | High — all parts separate and accessible | Medium — parts are compact, laptop-style |
| Screen repair | Monitor is separate — replace monitor | Screen replacement like a laptop (₹3,999–₹9,999) |
| RAM upgrade | Standard DDR4/5 DIMM — easy and cheap | SO-DIMM (laptop RAM) — same cost as laptop |
| SSD upgrade | Multiple SATA bays, easy access | Single M.2 slot — compact, harder to access |
| GPU upgrade | Add a dedicated GPU (PCIe slot) | Usually not upgradeable (soldered) |
| PSU failure | PSU is a separate, replaceable unit | Power adapter (like a laptop) — easier to replace |
Desktop Computer Upgrades Available in Mumbai
Beyond repair, desktops can be upgraded to extend life significantly:
- HDD → SSD: ₹2,499–₹4,999 — transforms boot time and performance
- RAM upgrade (4GB → 8/16/32GB): ₹1,499–₹5,999
- Add dedicated GPU: ₹5,999–₹25,000+ depending on card
- CPU upgrade (same socket): ₹2,999–₹9,999
- Cooling upgrade (better CPU cooler): ₹999–₹2,999
Power Surge Damage — Very Common in Mumbai
Mumbai's power grid experiences frequent voltage spikes, especially during monsoon season (June–September). A single power surge without a proper UPS or surge protector can damage the PSU, motherboard, and GPU simultaneously. If your desktop stopped working after a power outage or heavy rain, bring it in for diagnosis — damage is often limited to the PSU (₹1,499–₹3,999) and not the motherboard.
Prevention: An online UPS (₹3,000–₹8,000) protects the entire desktop from surge and outage. Cheaper surge protector power strips provide partial protection.

Is It Worth Repairing an Old Desktop PC?
Yes — in most cases. A desktop with a functional motherboard can be refreshed with a new SSD, more RAM, and a clean OS installation for ₹4,000–₹8,000 and will run like new. This is far cheaper than a new desktop PC (₹30,000+). If repair costs exceed 50–60% of a comparable new PC's price, we'll tell you honestly — we do not push unnecessary repairs.
