It sounds like your power supply is going out in your pc.
Try to determine the source of the noise. If you smell anything burning,
turn the pc off.....that is if its not food or anything of that nature. :0)
Be sure that you have the latest DAT files for your antivirus software. You
can go to the companies website and check for virus updates or the software
may also have an automatic update feature built into it.
Hope it helps!
