Why Did the PC Keep Shutting Down?
A customer sent in their PC for repair in Singapore after it kept shutting down on its own. Auto-shutdown can come from overheating, a failing power supply, or a hardware fault. When we inspected the PC, we found sticky oil residue on the case and around the system. The oil contamination was the likely cause of the shutdown issue.
Root Cause
Oil or oily residue inside a PC can contaminate contacts, trap dust, affect insulation, and cause unpredictable electrical behaviour. In this case, oil residue was found on the PC, and the system was shutting down automatically. Because the motherboard looked visually fine but the shutdown issue persisted, replacing the motherboard and CPU was the safer repair choice.
What We Checked First
- Shutdown symptom: confirmed the PC was turning off unexpectedly.
- Oil spill residue: found sticky oil residue on the PC case and around the system.
- Motherboard condition: old motherboard looked visually fine, but was treated as a likely affected component due to the shutdown issue.
- CPU area: CPU was also replaced together with the motherboard as part of the repair.
- Post-repair test: system was run after the motherboard and CPU replacement to confirm the shutdown issue did not return.
How We Fixed It
- Oil contamination confirmed: Opened the case and found sticky oil residue on the PC case and around the system. The oil spill was treated as the likely cause of the auto-shutdown issue.
- Scope of damage assessed: Motherboard and CPU were treated as the likely affected components. Other reusable parts were inspected before being kept in the build.
- Motherboard replaced: Contaminated board removed. Compatible replacement motherboard installed with all existing components transferred across.
- CPU replaced: New CPU fitted to the replacement board. CPU was replaced together with the motherboard as the safer repair choice after the oil-related shutdown issue.
- Extended test run: System powered on and ran for several hours. No shutdown occurred before being returned to the customer.

"Oil inside a PC is tricky because it does not evaporate like water. It can leave residue, trap dust, affect contacts, and cause unpredictable shutdowns. When the issue continues after inspection, replacing the affected motherboard and CPU is often the safer long-term repair."
- Mansa ComputersFinal Result
PC ran for several hours after the repair with no auto-shutdown. Motherboard and CPU replaced. Other reusable components were kept in the build after inspection.

Frequently Asked Questions
What happens if oil spills inside a PC?
Oil or oily residue inside a PC can contaminate contacts, trap dust, affect insulation, and cause unpredictable behaviour such as random shutdowns, boot issues, or component damage over time. Unlike water, oil does not evaporate quickly and can leave residue behind. If oil reaches the motherboard or CPU area and the PC continues to show faults, affected components may need to be replaced for reliable operation.
Can a PC be fixed after liquid or oil damage?
Often yes, if the damage is limited to specific components. In this case, the motherboard and CPU were replaced, while other reusable parts were kept in the build after inspection. The extent of the damage determines which parts need replacing. Bring the PC to our workshop at 1 Ubi View, Focus One and we will assess what can be saved before any parts are ordered.
How long does a motherboard and CPU replacement take in Singapore?
Most motherboard and CPU replacements at Mansa Computers are completed within 1-2 days. This includes diagnosis, sourcing the replacement components, installation, and a test run to confirm the shutdown issue does not return before the PC is returned.
