I am concern about my HP laptop Pavillion dv7; the problem that it may be having is the weird sound it's giving? There is the regular sound when you press the power button and it's I guess booting up. There is the regular sound to the fan which I never noticed until now which maybe it's louder the it's suppose to be. But there is this extra noise that may be the hard drive not sure but it makes like a scratching sound but then it sounds like a gurgle or even maybe static. The hard drive has been replaced a few months ago and I never noticed this sound until today plus when I am searching on the web I go to a website it goes to it like normal but then when I try to press the back button it doesn't work and even when I'm nott on the web I'm just in word I'm looking in a file and I try to save or go to another file it doesn't respond right away. With all these things happening what could it be? I know these are several issues but could it be multible things and not just the fan or hard drive because I no the file thing is software issues. My main concern is the hardware first. Please if anybody knows what to do to what it might be please reply back!
Thank you,
