recently i started to notice annoying unstoppable buzzing/rattling sound coming from my pc. its almost a continuous sound, but it gets noticeably louder and faster when i scroll my mouse up/down, watch a video online or open vlc player, etc..
even if CPU,GPU and memory usages are low the noise is still there.
i think this sound is located near the PSU, so most likely its coming from the PSU (I'm not 100% certain though).
the weird thing that this sound gets noticeably quieter only when i enter the bios. any explanation to that?.
there is also another weird thing.. i guess that noise is gone when i play a high demanding game, I'm not sure though, maybe the fans spinning cover over this sound.
i recently cleaned my computer case with blower, cleaned most of the components except the PSU fan.
my pc Temps are normal on idle and under load, i never had problems through the 4 years when my pc is under load.
i tried disabling C1E, EPR, C6/C3 from the bios, tried to boot from safe mode.. but problem still there.
Motherboard: Gigabyte H61M-S2p

CPU: Intel i5-3470
HD: WD Blue 1TB
PSU: Thermaltake 500W model TT- 500 NL2NL
Case: Thermaltake commander MS-III

any Help would be appreciated.
