Well my Dell Optiplex is now 5 years old. Warranty ran out March 24. So apparently it knows this because I have started to notice an odd whirring sound every now and then. Sound is coming from inside the case. No DVD or CD discs are in the optical drives.I am thinking maybe hard drive bearings? Only lasts a few seconds and seems to be at random times. No screen flicker or other symptoms occur when this happens.I have not shut down since noticing so I do not know what fun may await on start-up.Knowing that all electronics and spinning things do not like heat I have put a small fan behind the case. I figured it can't hurt.
I do not do use this for gaming or such. Mostly word and Office applications.
I use this for my small business so I cannot be without it. I am in the process of replacing the computer and should have one ordered within the next couple of days.
If anyone thinks this is the hard drive any thoughts about how long I may have before it quits?
If not the HD could this be a fan going bad?
Any suggestions on what to check is most appreciated
I always replace the entire system every 4-6 years. I apologize if this is a stupid question but if I brought this to a local computer shop before the HD dies could they just replace the HD and transfer all data to a new one?
As always input from the community is most welcome.
Best Regards

Hello and welcome to Bleepingcomputer.

The whirring noise you hear can also be caused by a cooling fan.

I suggest you open the computer case and try to locate the source of the noise for peace of mind.

You may have dust embedded in one of the cooling fans, or one of them is showing its age and needs to be replaced.

Thanks for the Reply MRBruce1959
I do hope it is just a fan issue. An external fan blowing through the back for a few days until the new system is ready will not be an inconvenience.
I will not be as paranoid about working on this once the data is transferred and I am up and running. It will become a family computer
I am leaning toward going with a RAID set up plus off site back up on the new system.
Have a quote from Dell. The business div. of Staples wants to quote also. Unfortunately it's tax time so the expenses just seem to be falling from the sky.
Oh well,need to keep things in perspective. Many people across the globe have a lot worse things happening.
Thanks again and Best Regards

If the sound is loud, it is most likely a fan bearing. Hard drive bearings are quite durable and not as loud until the very end.
