Frequently Asked Questions
Factual answers regarding diagnostic turnarounds, data preservation, and London callout visits.
Need Personal Advice on Your Repair?
Speak directly with a technician for straightforward guidance on your symptoms and available appointment times.
Call +44 800 054 6750Can you service my overheating computer on-site in London?
Yes. Our technician carries antistatic mats, compressed air tools, premium thermal paste, and replacement fans to clean and service your PC directly at your home or workplace.
How often should thermal paste be replaced on a computer?
For most desktop PCs and laptops, thermal paste should be replaced every 2 to 3 years. Over time, the silicone carrier oils dry out, leaving a chalky barrier that cannot efficiently transfer heat.
Why does my laptop get so hot even when I'm just browsing the web?
If the internal radiator fins are blanketed in dust, even low processor heat cannot escape. Background software tasks or browser extensions with high CPU usage will quickly push temperatures past safe limits.
Will clearing dust and replacing thermal paste make my computer run faster?
Yes! When modern processors overheat, they automatically downclock (thermal throttle) to prevent melting, running at a fraction of their normal speed. Restoring cooling eliminates throttling and restores full speed.
