Strange noise from pc


Established Member
For a while now when my pc is running a task that I'm guessing is using a bit of resources it starts making a right buzzing/shinning type of noise. Say like I'm using a video converter to do a film from mkv to xvid etc it really goes on one. Soon as I stop and its not under load the noise goes. It's an I5 processor and has 4gb of good ram so anyone got any ideas what it could be or how to even find out?

It's not just the CPU fan spinning up to compensate for the extra heat?

Funny noises (especially whining type noises) are often a power supply issue. Although it's more common on things like monitors, what make and model is your PC's power supply?

Most likely to be the PSU - is it a good quality one or did it come with the PC? If it bothers you then you may want to look at buying a new quality PSU.

Powercool PSUs aren't brilliant so that's definitely a candidate. Quite difficult to test though, does the noise get louder if you put your ear next to it?
