Weird Noise, Cant Figure out What!!!
alright guys/girls. umm whoever. i was reinstalling drivers for my dads ethernet card. well it asked me to restart so i did and then when it started back up i heard this really weird high-pitched noise.
i mean this computer is ****ty but i cant figure out what it is. i know it either the phillips burner. the cpu, or the harddrive. i also noticed alot of heat between the video card and the cpu.

some specs are (dont laugh.... ):
pentium II 333MHz
380MB ram
maxtor like 5gb hdd
4mb (hehe) video card

note: he mostly uses this for internet. theres no overclocking at all. and please dont laugh. lol

alright i think this computer is fried. i turned on and moved the power supply so i could see everything instead of having the damn thing in the way. well i touched the metal part of the harddrive and burnt my fingers. i went and touched part of the heatsink for the cpu and burnt my fingers

You say you "know" it is the burner, hdd or cpu. How? If you are correct, it isn't the cpu, no moving parts or ability to make noise. Its probably either a dying hdd or a dying fan.

I have worked with many switching suppies/circuits in the past and can say from experience that in some cases these circuits can produce a high pitched squeel without moving parts. If the switching component resonates at say 12,000Hz (which may or may not be the switching frequency), then it is quite probable that you will hear it. Does that make the circuit bad? I don't know. but if you couple it with

then yea, you have a most likely have problem. As QC manager for my company, the rule is "if you can hear it replace it", and we have replaced more than one switching supplies

Uh, maybe it's just me, but CPUs and graphics chipsets generate heat. That's the way it is.

Agreed that you don't need moving parts to create noise, power supplies being probably the most common example in the computer. That said, he still wasn't hearing the cpu.

One other common case for squeaking noises is when one of the wires inside the case gets caught inside a fan.
