I have a problem with my Hard drive 160 Gig with 111 Gig free space on it (I had Dell 5150 dimension with 3.00Ghz) but keeps on running so loud that it annoys me so much but the problem is my Firefox becames so slow that every click will wait about 15-20 seconds to change or use? Kinda really gave me some head ache about this problem, but if I switch to Internet Explorer I can use this browser easily while the Hard drive keeps spinning so loud. In order for me to use again Fiefox I have to re start my computer then Hard drive dies down means no more spinning loudly I can use Fire fox but anytime Hard drive will come back again to spin loudly? Within one day maybe 5 to 7 times that hard drive will spin loudly. This problem is almost 2 to 3 months already , any suggestion to solve this problem thanks in advance.
