Windows 10: Computer Noisy

Hello,
Recently when starting computer, there are some noises inside, (like a drill), it stops when the sign-in screen comes on.
After that it is quiet all the time. Only here and there it comes back for a moment when computer wakes up after a long pause.
Is something going to break ?
Answers will be appreciated
Thanks


:)

 

Noisy computer

Is it the disk drive or one of the fans ?

 

Noisy computer

My computer seems to always be running the background. How can I stop this. It is annoying.

 

How old is the machine, have you checked the inside to see how much dust there is.

 

Do you have CD/DVD reader ?

 

Hello,
Thanks for the answers.
1. The computer is with me about 1.5 years, I assumed it was new but it turned out it is not, hardware is old, this I learned later when had upgrade win 10 problems and ran some hardware testing programs.
I intend (hopefully) to buy a new one but this works not bad.
Opened it, dust is normal.
2. There is an optical drive, quiet and works nice.
Thanks again

 

CD/DVD drive may make that kind of noise while initializing, that's why I asked about it. If it's not much bother (there may be just one screw at bottom) you can take it out to try. Also take a look in BIOS, it may be set as default BOOT drive and trying to find a boot disk in it but can't.

 

Hello,
This is just FYI, recently I ran system's drive optimization, it did not show any fragmentation, but I then used "Defraggler", it worked for almost an hour. Since then, starting computer is quiet, noise gone.
Thanks for the answers.

 

Likely to be the death throes of a fan, it will probably get noisier then go quiet when the bearings are completely seized. Hopefully it will be a standard size and easily replaceable.
On a Desktop it maybe a Case fan, CPU fan, Graphics Card fan.
