my computer is making lots of noise

Well from experience I can tell your that noise coming from your computer is never a good thing. These are the things that make noise in your computer: fans, hard drive, CD/DVD/floppy drive. If your computer is making more noise than usual, its not a good thing. So the problem probably lies within one of those three parts. You say its not the fan, but there are internal fans in laptops that you can't see unless you take it apart. So it is possible that one of your fans is starting to go out. This usually isn't a big deal, but since its a laptop, which laptops tend to get very hot, there is a possibility of your laptop overheating if a fan goes out. If you don't have a CD/DVD in the CD/DVD drive, it won't make noise. So that's something you can check. Your hard drive makes noise, but if its louder than normal, it is a sign that it could quit on you, which is not good at all. If you have any important information on it, its probably a good idea to get it looked at. But I wouldn't take it to a computer repair store unless its your only option because they charge all kinds of fees and you can end up being charged a few hundred dollars just to find out whats wrong with the laptop. Hope this helped.

There are several possibilities for this, but it is not the kind of thing that you should allow to continue. If the fan is becoming clogged or maybe was revolving a little out of line then it will make a buzzing noise. You could also get this from a hard drive or even the DVD drive if a disk is left in. If the problem does not reappear then that is fine, but if it returns then you need to establish the cause before other parts become damaged by the vibration or by overheating. It would be easier with a desktop computer because laptops are a little more fiddly to open and examine.

My computer used to make a lot of noise sometimes. It was made by the fan. A week ago, the fan was completely broken and I took it to a computer shop and it was replaced with another one. Now it is working perfectly without making loud noise any more. It is silent. Take care, hotsummer.

I think you would be better if you get it checked by some technician. May be, these are signs of your computer system getting worse, or some problem developing. If you do not get checked it now, it might develop into a bigger, much more unmanageable issue later on.

Sounds like a dirty leptop. How often do you vacuum and clean it? That is something you should do at least twice a month. Vacuum all the USB ports, the battery, the fans and everywhere. Now spray with compressed air. Go to amazon and search for Stoner 94203 GUST Easy Air Duster. They are pretty good and cheap as well. What you wanna do is first spray all the USB ports and the ethernet port, and now the keyboard in between every single key (carefully). Now hold your laptop in one hand and spray on its back, and you'll see dirt coming out of the fans. Don't shake the laptop or anything, just spray on the back from top to bottom until there's no more dirt coming out of the fans. Now take out the battery and spray in there while you're holding the laptop. Last but not least spray the fans just to make sure everything is gone. Now you're done and can start your laptop. Now play a game or something that'll normally make the laptop noisy, and see the difference.

i think there is a bad sector in your computer

Last month my computer kaput. I could not switch on. Sent to the repair shop. The hard disk spoilt. The technician replaced a new WD hard disk and cost me RM 280(USD 95), inclusive of labour,

it simply indicates it is the ideal and correct time to move on for sure and make the best by switching to a new computer

oh my god, you must take to the computer shop and have it checked because something must be cooking in there. I am glad though that it is not making noise anymore. Thanks for sharing and have a wonderful day ahead.

May be that's because you must have been using your PC for more than what it need to run. It also wants rest so that it can perform with its maximum potential. But the way, your fan starts to sounds up coz your internal chips got heated up so much that to regulate it down I mean to cool it down computer fan speed automatically get regultaed to pull out maximum heat out of your PC. If you look carefully open your cabinat of your PC and look for your CPU chip. you will find a fan above CPU too besides what you see from outside at your cabinate powersupply. So next time also do take care that like your body like human body your system need rest too, so that they can survive more and often do perform more as what is needed.

I had this happen once, and my computer guy vacuumed the dust out. And never had that problem again. I would though have it checked by someone.

I've had this happen to me.As said already,better to get your system checked.ALso one advise is that do not place your system on top of any cloth,because it will get heated sooner and eventually go into repair.I learnt this the hard way.Hope this is of use to my fellow lotters here:)

I think it feels like it is a problem with your fan do you have a computer or a laptop? You shouldn't make it overheat or otherwise it is bad for the lifespan of the product as well as the internal parts and electronic chips. Good luck!
