The only thing you can do about this is try to make sure it is clean and nothing is preventing it from spinning. Make sure it is not seizing up. GX270 is pretty old pc so it might be just fan it self going bad. I had a dell pc that was about as old as GX270's and my fan fell off the motherboard while spinning. Hope this helps.

My Dell optiplex gx 270 tower's chipset heats up and system shuts down and my friend's gx270 mother board is burnt due to same reasons


check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in

check you CPU make sure its securely seated and has thermal grease might be getting to hot


another possible reason could be a memory dump you might be running to many programs at the one time putting to much strain on the CPU central processing unit


hope this helps

Hi...am waqar... have pc dell gx 270, which is off by heasting of main IC.. iam very dirstrub by this


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the 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 with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

I have a Dell Inspiron 530. Was getting 2 quick beeps on start up and loud fan noise. I replaced the cpu fan but the one I bought did not have the right plug for the motherboard connection. I had to modify...


This model (as well as many other Dell desktops) has a DUAL SPEED CPU fan. If the motherboard detects that the CPU temp is running hot it will increase the speed of the CPU fan to lower the temp of the CPU. You should do a Google search for the correct CPU fan and purchase it and install it back into your computer.

My computer fan speeds up whenever I'm on the


Nothing ... probably ... your fan speeds up when the processor temp goes up ... the more you are doing, the more cooling you need. The processor is calling for more cooling so the fan runs faster.

If this is a concern for you, you may wish to consider adding another fan to your case. In any event, make sure your power supply fan is clean. Use a vacuum or canned air to clean.

Dell optiplex gx270 shuts down when cpu setting is on normal but runs when on compatible mode


The GX270 has a manufacturers defect with the motherboard. Open up the case and look at the capacitors, they look like a bunch of upsidedown double AA batteries sticking out of the board. The capacitors on the GX270 are bad if you see a crust on them or some kind of brown liquid, DO NOT TOUCH this it is battery acid.

Loud "jet engine taking off" type sound


If you changed out the power supply then the only other device that could be making that noise is your CPU cooling fan. To be sure, open the case and disconnect the CPU cooling fan plug from the motherbrd (MAKE SURE POWER IS OFF) and see if the noise stops. Don’t worry about the “Fan Failure Error” when you turn on the computer. Just hit F1 to continue. Don’t leave the computer running without the fan plugged in longer then necessary. After tying this procedure, please contact me for further diagnosis.

Dell opteplix gx270 problem


It is either dust build up on the CPU heatsink under the fan or that model is known for blown capacitors...
Open case and check motherboard for blown capicitors and / or dust build up on CPU heatsink
And if there are any bad capacitors then you will need to replace the motherboard.

Dell motherboard {GX 270} over heating.


Hi

It seems the system is "dying" or already "dead". The initial heat issues suggests a faulty Processor (PRC) Fan. Faulty Power Supply Unit (PSU) Fan can have same effect.

Open the Base unit; disconnect everything (incluiding Keyboard, mouse, network) power-up and check that PRC and PSU fans are working.

Also check the QUAD Pack Diagnostic LEDs and compare the sequence with http://support.dell.com/support/edocs/systems/opgx270/en/ug/solve.htm#1235408.

This will help with identifying the cause. Try the Dell Suggested Resolution.
