Most common fan which may generate noise are the cpu fan, case fan and video card fan. if you can open the case and determine where the noise is coming from, check if the fan generating it has physical issues like loose wires or screws or if the blades are touching the plastics which may be able to adjust to stop the source of the noise. if the noise is a result of the fan spinning very fast, it might indicate a possible heat issue on the system. try updating the BIOS of your motherboard which you can usually download from the Dell's support web site then searching for your system's service tag or model. BIOS updates may include fixes or improvements for thermal handling and fan performance. if it does not help or if the issue is more physical then performance, getting a replacement would be your next step. hope the info helps.

Its important to try and distinguish where exactly the noise is coming from the most typical example of this is the PSU fan (Power Supply Fan). The above also is very correct but its better to eliminate each point of failure.

SOURCE: Dell Optiplex GX240 performance problem and fan noise

The fans on Dell power supplies are rather noisy and prone to failure. Find out if the noisy fan is inside the case or inside the power supply. If your computer has become slow you should scan for viruses and spyware. If the scan does not improve things it may be time for an upgrade.

The GX240 only supports up to 1 gigabyte of RAM, you should have the maximum installed. I would not spend more than $50 upgrading this computer, you can find better used ones in the $100-$200 range.

SOURCE: Dell OptiPlex GX620 starts up then shuts down repeatedly

Try this: remove the DMOS battery and unplug the on/off switch plug. It's the one in the corner near the power supply. To be sure follow the cable from the front on/off switch board on back to this plug. Then plug the A/C cord in, if the system boots up fine, then replace the front panel power on/off swith board. Naturally you will not be able to power off the computer using the power switch (since we unplugged it), so you will have to just pull the plug. Hope this helps. Joe

SOURCE: my dell optiplex gx620 fan

Three possible conditions of fan noise.

A condition of functional computer component parts
first, an overloaded memory due to several programs installed on the desktop bacground
second, a disk in the driver compartment generating fan energy to cool the system. Caused during movie displays using the computer disk drivers, or burning disks with the disk driver. Third, an extensive use of the computer requires more fan energer cooling capacity.

solving fan over tasking

1. free up the computer memory requirements by removing malfunctioning software programs
2. perform a computer defragmentation located by clicking START, PROGRAMS, ACCESSORIES, SYSTEM TOOLS, selecting the options disk defragment
a. defragmenting redistributes files into spaces producing an effeccient memory function requiring least fan capacity.
3. perform a computer malfunct programs cleanup by clicking START, PROGRAMS, ACCESSORIES, SYSTEM TOOLS, selecting the options of disk cleanup
a. the disk cleaning removes remnants of fragmented files making performanc effective requiring least fan generate energy



conditions of disfunction condition in a component part
1. a broken component of the computer system impeding the fans effective performance
a. a foreign object in the fan compartment causes loud noise
b. a broken fan due to over heating
c. a manufacturers condition of prior computers that performed on fan cooling rather than heat sunk dispensing and obsorption

Where does a dial up modem go in a Dell optiplex 760?


The dial-up modem would install inside the computer in a PCI slot. VERY easy to install but a couple considerations before doing so... There are different sizes depending on whether the OptiPlex is a mini-tower or small form factor case. Also - you would need drivers for the modem that are compatible with the operating system you have installed on the computer.

I have dell optiplex 760 core 2 due,i notice that when i worked on internet my computer automatically restart after some time,,,,,plzzz tel me solution


Check whether the CPU Fan is working (try to listen for Fan noise).
This is typical of CPU overheating. Detailed Memory Test can be performed during bootup to prevent PC from even booting up if there is a memory fault. There are free programs on the web to run detailed memory tests. You can use these to verify. However, one simple method to verify is to put a small fan on the air vent of the Dell and check whether your PC still has the symptoms. If it does, then the problem is not CPU heating up.
