System Interrupts & USB's

[Munroast]

I have a lap top that is like wading about in deep mud, when I look at Task Manager CPU is always running +50% with the biggest culprit being "System Interrupts"

t'internet suggests Root USB's as a possible culprit and try disabling them. They seem to be right, when I disable 'Root USB' the CPU starts running below 5%.. and computer is fine!

But I need USB's, so what m I supposed to do now ? I'm thinking the USB is all part of the motherboard, so is the laptop bolluxed?

And yes I have made sure they have the latest driver installed.

This article suggests its OK to uninstall the driver and allow windows to reinstall, I know, unlikely to solve, but worth a shot : https://support.microsoft.com/en-us...-suspend-99b5ae85-69cb-4f94-adce-5698ba44804f

I take it you have no USB devices plugged in when testing? Could be a dodgy device if so.
