Question about Microsoft Windows XP Professional Full Version (E85-00086-RB) for PC
Help! It's annoying!
Okay. There are three things it can be. Let's start with the first one, and see if we can rule it out.
1.I would like you to look at the Electrolytic Capacitors on the motherboard. Specifically the one's that
surround the processor.
These are the small aluminum cylindrical 'cans' on the motherboard. This link will show what they look like,
and show what they look like in a bad state. (Electrolytic paste leaking out, and/or sides/top, bulging),
Electrolytic Capacitors that are located in close proximity to the processor are used as Voltage Regulators.
The processor has to have a 'clean', steady supply of DC voltage, and has a very tight tolerance range
for the voltage. It cannot be too much, or too little, or the processor will turn off.
2.With the computer case open, computer running, listen close to see if this sound is coming from the
harddrive. Do Not reach inside the computer while it is running, (And plugged in) It would seem as if I'm
warning you about getting shocked, but it isn't. It's that you may transfer static electricity from your body,
and burn out the delicate hardware components. Your computer uses three voltages. 3.3 volts, 5 volts,
and 12 volts. To be shocked you would have to be standing barefooted in water, and grab something inside
the computer, or stick a small metallic round object in one of the power supply case's ventilation holes.
Your harddrive has round metal platters inside. These resemble metal CD disks. There are arms with
Read/Write Heads for every platter. Two for every platter. One above the platter, one below the platter.
There may be 3 to 6 platters inside your harddrive. The Read/Write Heads are located a few thousands
of an inch above,(And Below), the platters. These arms can go back and forth across the platters at Hundreds
of times a Second!
The boot sector for your Operating System, (Windows XP is an example of an O/S), is on the outside edge
of one of these platters. The Read/Write head could have touched the platter, and scratched the boot sector.
Harddrive is now defunct.
3.The Power Supply's Electrolytic Capacitors could be failing, or some have failed. The power supply won't
put out the full needed voltage, and the processor doesn't 'Play this Game'. (Steady, clean, supply of DC
voltage) The only way to check, is to substitute the power supply with a known, good, compatible one,
and test the computer.

The DB gauge is for decibel output. That is really just for aesthetics, but is functional if hooked up properly. I have the same case. Does the sound come from the psu, cpu fan or other fan in the case?
