Hello. My CPU is loud, even when it's idol. I think it may be a combination of a loud harddrive and fans and even possibly the power supply. I do not have the resources to replace them all or to buy a whole new computer. The problem is that the hum can be heard over my recordings. Does anyone have any suggestions to subdue the sound? Having the cpu in a different room or even farther away is not practical and neither is the casing they sell for about $300. I'm hoping maybe someone has had this happen before and has a suggestion or two? Thanks.
