Laptop whines/screeches on powerup

[newjackcity]

i have had my laptop for about 2 1/2 years. I rarely turn my comp off, annoying internet problem, and i let my comp go into sleep mode. Every time i "wake up" my laptop, it gives off a high-pitched whine, for about 5-30mins. This also happens on bootup. any ideas on what the problem may be?

I can think of two things:
- The fan is clogged with dust
- Time to replace that hard-drive

If you gonna treat your hard-drive in the same way a web data-centre does, then get ready to replace it every 2-3 years. As for the fan, you'll have to unscrew the back of your lappy and spray pressurised air to blow the away.
