I have a problem, the problem is when I turned on my computer, the computer got noisy and I did not know what caused that noise. What is wrong? Can somebody help me?

The problem is usually a fan: CPU fan, power supply fan, or chassis fan. It is usually a CPU fan with a bad bearing. Listen for the power supply fan at the back of the computer to see if that is the cause. Remove the lid to determine if it is the CPU fan or a chassis fan. It could be the hard disk drive. Again, remove the lid so you can listen more selectively. You may have to disconnect the CPU fan or power cable to the hard disk to tell which one it is. Don't pull the hard disk power cable unless the computer is off and unplugged from the wall. If it is the hard disk, it is time to back it up, if you can. Sometimes, a CD-ROM or floppy will start making noise, but it is rare. If it is a CPU fan with a cheap bearing, it may metalic dust from the bearing on the motherboard, etc. Be sure to clean-it-up (with the power off, of course). Larry

I examined it and it was the CPU/cooling fan which was making all the noise, so I need to replace it with a new one. But the problem is that I do not know which one to buy, I got a pentium chip (200 Mhz), so is it socket 7?

Yes, you need a socket 7 CPU fan. Get one with a ball bearing, see the Vantec Review: http://duxcw.com/digest/Reviews/cpufan/socket7/vantec.htm. If your motherboard BIOS has system monitoring (I doubt it from your description) and a place to plug-in the CPU fan then you want a 3-pin fan. Otherwise get one that plugs into one of the power supply connectors. Larry

Buzzing and vibration are somewhat odd... It could be the CD-ROM drive and it could be "normal" for some drives. It would normally happen when a CD is first put in the drive/when the computer is reading a CD. It is made when the drive is spinning-up to speed. Some of the AOpen drives, for example, are like that. It could also be abnormal, but I can't tell because I'm not there. It could also be coming from one of the fans or hard disk drive. And experienced computer tech should be able to quickly narrow it down and determine if there is a problem. Larry
