Why people book this
Computer repair should start with a proper diagnosis, not a guess.
Verge Tech repairs laptops, desktops, Macs and gaming PCs with a fixed quote before work starts. The priority is to protect your data, identify the fault, explain the options and avoid spending money on a device that is past economical repair.
Laptop shuts down under load
Sudden shutdowns during video calls, gaming or updates often point to heat protection kicking in.
Fan constantly loud
Dust, blocked vents, background software or dried thermal paste can make the fan run hard all day.
Slow performance when hot
Thermal throttling reduces CPU and GPU speed to protect the laptop. Cleaning often restores more stable performance.

What we check
Overheating is a symptom, not always the root cause.
A proper service checks airflow, thermal contact, fan control, software load and hardware health before recommending parts.
Airflow
Dust mats inside heatsinks can block air even when the outside vent looks clean.
Thermal paste
Old paste can dry out and stop heat moving efficiently from CPU or GPU to the heatsink.
Fan health
Grinding, rattling or non-spinning fans may need replacement rather than cleaning.
Software load
Malware, bad drivers and background apps can keep the CPU busy and create heat.
FAQs
Questions people ask before booking.
How do I know if my laptop is overheating?
Common signs include loud fans, hot casing, sudden shutdowns, performance drops, blue screens, or the laptop slowing down during gaming, video calls or updates.
Can cleaning fix an overheating laptop?
Often yes, especially when dust is blocking the heatsink or vents. If the fan has failed or the heatsink is damaged, parts may be needed.
Do you replace thermal paste?
Yes, where it is appropriate for the laptop design. We explain this before opening the machine because some models need more strip-down work than others.
Can you fix gaming laptop overheating?
Yes. Gaming laptops often need CPU and GPU cooling checks, dust removal, thermal paste service and fan behaviour testing.
Is it safe to keep using an overheating laptop?
Not for long periods. Heat can shorten battery, SSD and motherboard life. If the laptop is shutting down or too hot to touch, stop heavy use and book a check.
