I have built a fairly new pc about 2 months ago and I have noticed a faint beeping/chirping noise coming from the hard drive that comes randomly every few seconds or when under load. It gets worse under load and sometimes grinds. Is this not normal? Should I consider getting a new hard drive? It's a Western Digital WD Blue WD10EZEX 1TB http://pcpartpicker.com/part/western-digital-internal-hard-drive-wd10ezex
