Sounds like a classic case of overheating. Check the thermal compound under the heatsinks and replace it with Arctic silver 5

Dell Optiplex GX280 has very high processor fan noise.


Hi
Generally Dells run very quietly, so there are three possible problems here.
The first is that excessive noise can be caused by the fans having to run faster than usual to keep the temperature down. In this case you need to check and make sure that all the airways and interior of the computer are clean and clear of dust, which can build up in such a way as to seriously obstruct airflow. If this doesn't help there are normally at least 2 fans in the computer, one for the CPU chip and the other in the Power Supply. If it definitely one of these the only real way to cure it is to replace whichever is causing the problem.
You can download a very comprehensive manual for the GX280 here:
Product Support Dell US

by clicking on the "Users' Guide" link. This will download a pdf file which can be saved to your drive for future reference. The manual contains detailed instructions for these types of things, easily accessed by an interactive menu system.
Since this is quite an elderly system, you may find, that after pricing any replacements necessary to cure the noise, it makes more economic sense to put the cash towards a more up-to-date system.
Hope this is helpful, if so would you please register that with Fixya
Cheers

Dell optiplex GX280 tower machine, pc reboot again and again, fan run so fast and make alot of sound, also power light blink red instead of green, i have changed rams but facing same problem, what sho


Hello here is the home page:

http://www.dell.com/support/drivers/us/en/ussoho1/Product/optiplex-gx280

I think you have some kind of a virus or malware on your system.

Install this program and make a full scan:

http://www.malwarebytes.org/products/malwarebytes_free/

You maybe have to start the pc in failsafe mode by pressing F8 while you reboot.

Install also a better FREE antivirus program:

http://www.microsoft.com/en-us/download/details.aspx?id=5201

Please uninstall any other antivirus programs before you install microsoft security essentials. Run a full scan when installed and updated.It`not great to have more than one anti virus program installed. Most antivirus programs have a background scanner running to protect you from virus vhile you surf on the internet open a file etc.With more than one antivirus program the pc`s performance will be decreased.

There are a lot of things that can cause a computer to shut down.This could also be the power supply.Try also to renew the thermal grease between the cpu and the fan but BE CAREFULL not to damage the cpu.
If you are unsuccessfull at resolving the problem visit a computer repair shop.

When you talk about checking memory, it's the physical RAM stick inside the computer. RAM does not have sectors like a hard disk drive. If it does happen to be bad I'd replace it with at least 1GB to 2GB. 512MB is really low.

Good luck

Dell optiplex GX280 PC when power on system no noise with fan after one hour making loud noise . I changed the CPU fan , also same noise, and applied heat sink paste to CPU and heat sink same noise....


There probably is another fan, located inside the power-supply, that is making all the noise.

Borrow a stethoscope from a nurse or doctor, and listen to the noise, to pinpoint "where" on the computer that is the origin of the noise.

Dell Optiplex GX280 - On power ON , no Fan movement no display


Confirm no leaking or bulging capacitors on your mothboard.
refer to here
http://en.wikipedia.org/wiki/Capacitor_plague

As this was a common problem with the GX280.
If found, you will need to replace the capacitors.

The other check is to make sure the heatsink is fitted correctly, perhaps reaply the thermal paste if you have any. I know that high temps would switch the GX280 off.

Dell optiplex gx280 makes loud fan sound at startup and enters windows screen, but will not finish booting and freezes up.


You may have a problem with your power supply(the loud fan noise) and eventually it may get too hot and will cause problems like not fully booting.

GX280 - is it the motherboard?


Go here and download this program.

http://www.download.com/SpeedFan/3000-2094_4-10067444.html

This program will control your fan speed based on your cpu temp. It's main use is to quiet fan noise.

Dell Optiplex GX280 boot problem


I just repaired two Gateway systems with similar behavior (turn on power, fan runs at full speed, no boot), and both needed replacement system boards. (These were a different model, but the symptoms are typical of a dead system board.) I got the boards from a company called Blue Raven Technology (www.blueraven.com).

Before deciding the main board is bad, try another power supply to make sure that's not the problem. Also you might try clearing the CMOS memory on the system board (either by moving a jumper usually found near the backup battery, or by removing the battery itself). Sometimes corrupted CMOS data will keep the system from booting.
