i am facing this strange problem from last few days.
a strange noise coming from my cpu & when that noise increases my pc just turns off like power cut off.
first i thought it was my 2 hdd, i removed them still same noise, i disconnected all fans & even processor fan, still same.
what could be it then???
i removed all fans, hdd's, cd/dvd drives, even processor 4 pin power supply, STILL SAME BUZZING NOISE.
noise is like if u scratch a screw on metal or something like that. i also checked my processors tem, those r normal in range of 36 degree to 43 degree's.
my conf is as follow.
asus p5kplam/ps mobo.
4 gb ram
palit 9400 gt 1gb gpu
2 sata-2 WD 320 hdd.
a VIP 400w psu(i suspect this is the component making noise, because pc just shut's off after that noise increased!!!)
i already done cleaning with vaccume cleaner in reverse function.
IS THERE ANY POSSIBILITY THAT A PROCESSOR CAN MAKE SUCH SOUND, I READ IT ON GOOGLE THAT SOME PROCESSORS CREATE SUCH SOUNDS!!!!!!!!!!1
The high pitched noise you may hear from a processor is so unlikely to actually be audible by humans that I am inclined to agree with Ghnader and Venj,
Remove the psu from the pc, plug it into the wall by itself, then short the green pin on the 20+4 connector with any of the black pins, the psu should start up,
do you hear the noise still?
post back your findings please to confirm/ eliminate this from the list
ps, you may have caused some damage to the processor when you unplugged the fan on the heatsink, you should never run a processor without its heatsink/fan.
CPUs have no moving parts, and no noise while running.
The noise like a high pitch humming is probably coming from the transformer inside the PSU. This transformer has 0.5mm thick laminations compacted together either by rivets or by a weld bead. When this gets 'loose' the minute air gap between the lams will cause the lams to vibrate and hum. This humming may be transferred to other parts in the computer.
aaahhh life is so strange
i discovered one new thing, climax in the story guys!!!!!!!!!
we have inverter in our house because of load-shading prob(power cut off in 1 or 2 times in a day)
i noticed one thing that when ever main electricity is not there & all house running on my inverter the "strange noise" prob vanished at that time & my pc works as perfect as new one.
