I'm using Window XP service pack 2, currently i hit this problem when the computer entered standby mode, the power supply and the fan are still on. I was thinking it might be the power supply problem.
Could anyone helps me pls.
Varies with the computer brand and model... but you need that power supply on in some fashion... and different designs handle it in different ways.
It would be helpful to know your computer brand, model, and configuration.
