New Acer laptop noise?

From the moment it boots up, the computer has a whirring-humming sound to it (maybe the HDD spinning). It's slight, but noticeable and noisier than my earlier model Acers or Lenovo laptops. Is it anything to be concerned about or is this normal for newer laptops?

How do I download music into my file on my computer?

I don't want to download it from my phone. I want music off the internet, and I want to put it in my files. I'm trying to put music into my YouTube video, and the only way is through my files. I will give the owner of the music credit, but I just need to know how. I don't know if this helps, but I have a Lenovo ideapad 510, windows. Please let me know if you know how to do it, thanks!

Which laptop is best for college?

Budget laptop: Acer or Lenovo?

For basic use; music, YouTube, documents, some games, but nothing too serious. I'm looking at a Lenovo 110 15isk and an Acer ES 572. Is one any better or more reliable than the other?

Lenovo laptop restoration. One-Key Recovery or Windows 10 Reset?

I want to reformat my Lenovo 110 system to complete, out-of-the-box factory settings. If I use the "Initial Setup" program, will the system retain or preserve any image of what had been used prior to running it (and thereby take up space on the hard drive)? Would a full "Reset" through Windows 10 work better to wipe it clean and restore the system to real, authentic factory set conditions? Which program should I use to restore all the original disc space and settings?

Trying to figure out which Inspiron 15 700 gaming laptop to get

This is the 7th generation model: https://www.amazon.com/...06XFGF7SN/

And this is the 6th generation model: https://www.amazon.com/...B9HQI2KE75

And I believe this one is also a 7th generation from the Dell website: http://www.dell.com/...I4In1dfV19

I also saw some good things about this one, the Lenovo Y520, but it's pretty high on price tag. I'd like to spend around $800 if possible: https://www.newegg.com/...13721&SID=

Mainly I'd like to know the differences between the first two (which one is better) because those two are most near my price range. If you can help me out it would be awesome, thanks!
