Question about Dell Computers & Internet
My Dell Optiplex GX280 P4 SFF Desktop Computer has very high processor fan noise. Is this mother board issue or fan only issue? If it is curable, how?
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:

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

SOURCE: 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.

i had same problem today and i tested my machine and solved the problem at last.
the problem is the thermal value that your mainboard sets for your cpu.
please replace the mb.
ps: before this process,i tried almost everything . cpu fan , memory , cpu , cables ,case ... everything. but the problem is on your mb.
