Solve : Power Supply Sound - Something not getting enough power?

1.	Solve : Power Supply Sound - Something not getting enough power?
Answer» Ok ill start out with my computer specs OS - Windows XP SP2 Processor - Althon 64 2.0 GHz Graphics card - Geforce 7800 Power Supply - 450w Hard Drives - 80 gig, 250 gig CD DRIVER - standard nothing special Ok HERES my problem, my power supply has started making a high pitched noise that usually means something is not getting enough power. The REASON i say not getting enough power is because it comes and goes, its not always there. i have tried opening up my computer and making sure that all the connection are connected, i removed my sound card to lighten the power load on the PS. What im looking for in a reply is any other thing that might be CAUSING this. If the PSU is older than 4 YEARS replace it... You risk damaging components by under-powering them
