Gaming PC Performance Issues
A gaming PC that was once fast but now stutters in games, takes two minutes to boot Windows, or shows unexpectedly low frame rates even in older titles has a performance problem that's worth investigating. At Mr Gadget in Rickmansworth we diagnose gaming PC performance issues across both hardware and software domains.
Our performance service covers CPU and GPU thermal throttling analysis, RAM speed and XMP/EXPO profile verification, SSD health and speed testing, background process and startup item audit, driver version diagnosis, Windows power plan and process priority optimisation, and full storage clone to a faster drive where the bottleneck is I/O. We give you a clear before-and-after performance report so you can see exactly what changed.
