Windows 7: Cmos battery changed but hard drive is producing strange noises...

Cmos battery changed but hard drive is producing strange noises...

Hello Friends... My PC was giving, system battery low, message so i replaced cmos battery but it didn't boot until i set bios to its default values so finally i was able to boot but my hard drive is making strange noises now so even if right click and press refresh in the dialogue box, my hard drive produces sound and a light appears on the front of casing where i think Hard Drive is located.... Some kind soul told me to change my bios to its previous settings but i am wondering how do i do that?? is this strange behavior of my hard drive related to Cmos battery change or alteration of bios settings?? I just realized that i have made another thread probably too soon but i thought i should have a different one for a different question but still my apologies to Admin... Thank You...

I dont think the 2 are related. your bios has no effect on your harddrive once the system has posted. once windows starts loading its windows drivers that run the show.

I beleive your hard drive might be on its last legs. you could run some hard drive utilities to test for bad sectors ect, but in the mean time id grab yourself a spare harddrive and back everything up just in case

"my hard drive is making strange noises" could mean many things. And very often people mistake noises from other parts of the system as "hard drive noises".

If you can describe the sound that would help.
If you do a YouTube search for "hard Drive noise" you may be able to find one that sounds just like yours. Then post a link to it here.

Are you able to start and get into Windows now?

I would post any questions you have about the BIOS settings in the other thread, and post questions about your hard disk here. They are two separate topics.
