I have a vostro 200 large tower with a g33m02 motherboard. The cpu cooling fan is very loud. (not bearing loud, but it seams to try a lot harder than it needs too for what the computer is doing.) the cpu fan has a 4pin connector. r,y,black,blue. Do you know of any replacement fans or CPU adjustments which could shut this jet engine up? Thanx guys

many times if the fan over the cpu chip on the motherboard fails to run or blow, an beeping alarm will begin and PC will not start. the cpu has to be kept cool so if fan fails the startup is stopped. have found lose wire connections from fan to motherboard terminal, or power supply may be blown, try checking those first. if nothing lose then wiggle those wires to see if the fan starts.

Change the RAM modules or clean it and reinsert

Hi you can find the manual here

You need to use DVI to VGA convertor but mostly it is recommended to use a dvi compatible monitor. VGA wont work. Im pretty positive

Hi, its not a good practice to use a pc without a CPU fan. most cases the fans pc shuts down to prevent damage to the CPU. i will advance you take it to a technician to have the fan replaced. then it will work if the CPU has not already been damaged by you trying to use it without the fan. but i am sure that is not the case. get the fan changed and you pc will work again

When the CPU overheats then it will shutdown (i.e. thermal overload) and won't boot up again until it has cooled down.If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.

Yeah usually towers are pretty loud; but loud is good, because then you know your fans are working and you do not want the fans to stop spinning.

Try installing drivers for your CPU, or look at the settings for your video card, or look in your BIOS; there may be a setting or driver that enables automatic control of the speed of the fans, based on the heat.

This problem has repeatedly been reported with this model and the 4800. People will tell you it's the power supply, motherboard and CPU. It is none of those. Your CPU cooling tower has been jarred loose. Dell made these things way too big, and as a result a simple bump to your case can make everything go crazy. Remove your fan shroud, then the fan then the cooling tower, cleaning each as you go.
Now remove the large cooling tower. Remove, clean and reseat your CPU, add NEW thermal paste and reassemble everything and keep the PC on it's side. The system should now be able to reboot. In extreme cases of jarring such as the PC has been dropped etc, your motherboard may have been damaged. In this situation it is best to buy a new motherboard and transfer all your components to the new board. So far, I haven't had to do this though. Most of these PC's come back to life easily with the steps I just mentioned above.

Check your cpu fan, chassis fan, and the fan on the power supply. If all the fans are working then the bearings in the hard drive is about to go out. That is if you are not using a cd or dvd rom.
