Question about Dell Dimension E520 PC Desktop
As of a few days ago, my PC would make a loud wine in about 5-10 second intervals.. I opened it up and sprayed out dust, now there is a constant buzz going, but the PC is working fine, no other problems.
This could be your fan bearings going bad, or a ribbon cable rubbing next to a fan while it's spinning.
If it is your hard drive, then you should make a backup of your files (you should do this anyway), and then run a hard drive scan utility to check for bad sectors, or S.M.A.R.T. errors.
Here are a few I found from Google:

This could be a sign of a failing hard drive - I would backup all of your important documents immediately to an external drive to prevent you from losing any important data.
As you have already cleaned out the dust , there is a chance that one of the system fans (or the CPU fan) may be faulty or some wires inside your system case might be catching on the fan while it is spinning.
Disconnect all the system fans , so just the CPU fan is left plugged in and then switch on the system and see if the noise has stopped. Then plug each fan back in one at a time to identify if any of them are causing the noise.

Testimonial: "Thanks guys.. Backup is done, one question, when I plug the system fans back in, should I still have the system on, or turn it off before plugging each one in?"
Leave the cable connection as it is. That is, one ribbon cable for the 2 dvd drives and the original cable for the old hard drive. You dont need to set the jumper on the second hdd. It has to be set to 'cable select'. Then make sure to connect the second hard drive to the middle port of the ide cable. Don't forget to connect the power connector to the drive. It should work that way.
Two ports on the motherboard
primary ide controller port (for master and slave hard drives. both drives jumpers should be set to cable select. then make sure to connect the right ends of the cable to the drive. middle port is for slave. port on the end is for master. check the power connectors for both drives.)
secondary ide controller port (for 2 dvd drives.)

It certainly does sound that way.
Download Speed Fan and check your hard-drive's SMART readout. If it looks bad, back up your files and be prepared for the worst. If however the readings look fine, try defragmenting your system with the assistance of the free trial of O&O Defrag. Running the Complete/ACCESS defrag method will ensure that your files can be read as quickly as possible by the hard-drive without all the fragmentation.
NOTE: You may have to defragment more than once before this issue is cleared up. Severely fragmented hard-drives are never fixed with the first defragmentation.
Let me know if I can help you further, I certainly do hope things turn out good for you.

the key issue on the uncommanded shutdown is the POWER LED. If upon shutdown, the power LED Flashes AMBER, then the power supply is suspect.
If no flashing amber indication, then the next think I check is the heatsink (Processor overheating) remove, clean and apply arctic Silver heat transfer paste, see if the issuje goes away
Last but not least if the system is failing to boot, and displays a 3 4 diag LED code, then you may have a RAM module that is bad or may just need reseating. Running diags off of the Rersoujrce CD is something to look at too
