That may be all it was. I open up clean out and vacuum my PC once a year. Very easy to do. Carefully clean all the dirt that builds up on the fans. Cleaning the fan on the video card (if you have one) is a PITA. Once done the PC runs quieter and cooler.Thanks so much for all the suggestions and help! I cleaned the fans gently as suggested, and voila, no noise!
Mehanical HDDs have a 5 year life expectancy, + or - a couple years and over time they all will fail. Backup is essential and easy. Just get an external HDD and transfer over to it (simply drag and drop) any files, pix, music, etc you want to save. Drives are cheap.
SSDs have come down in price and are now IMHO cheap. Got a 128 GB SSD a couple years ago for 80 bucks USD. Use it for a boot drive with just the OS and a few fav programs and it runs GREAT with blazing speed....boots up the OS in ~10 seconds! Heard the new SATA-3 SSDs boot in a couple seconds! Won't ever go back to mechanical HDDs, which are only used for storage and additional backup now.
