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

My dell GX 270 computer has amber mother board light,No display,processor fan runs,power supply fan rotates.


hi ansilesh

If the power light is steady amber - The computer is receiving
electrical power, but an internal power problem might exist.
Ensure that the microprocessor power cable is securely connected to the
system board.
it might also be a failed mainboard already since you are experiencing a blackout.

hope this helps

My pc starts normally, but after an hour or two when i click windows shut down windows closes, and no signal message is shown on monitor.But the CPU Fan, GPU Fan & Cabinet Fan running normally,they...


Hi,

There are two harware you should check,


First the memory, it might be malfunctioning, if you have an extra memry card, try to swap it just to test the syatem.


Second will be the power supply unit or PSU, that is already overheating and shutting itself down, thus its not powering the your hard disk. try to replace it if you have an extra PSU.


Those are the most probable problem you have, PSU is the main problem in any desktop that was always been overlooked!


Hope that helps you out!


Thanks for using Fixya!

Pc not starting from pressing power on. Green LED for SB_PWR is on and when power switch pressed, fan & cool fan flicker momentarily but nothing happens. They do not spin. No LED light appears on front...


> PC had been suddenly powering off several times intermittently for a few days leading up to this state. Does this mean the PSU or Motherboard is at fault?

Yes, either CPU or PSU or motherboard are the likeliest culprits.

It's easier to try a different PSU than to try a different CPU or motherboard.

Dell Otipllex GX270. CPU fan won't speed up when CPU gets hot. I can trouble shoot if I can get a schematic.


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.

PC wont boot cpu fan runs extreemly loud and fast.


You may have a failed motherboard or bad/weak poswer supply unit (PSU) then. Failure of motherboards is usually due to breaking capacitors. A few years ago a capacitor company stole the "recipe" for making capacitors from another company and tried to make their own, unfortunately they did not get the ingredients right and the capacitors started breaking after 2-3 years of use. They sold these capacitors at very cheap prices and a lot of computer companies and power supply makers bought them. The DELL GX270 and GX 280 were the main DELL models affected by this situation. This is easy to diagnose. Look for capacitors (caps) (they look like little tiny soda cans) on your motherboard (mobo). They should be perfectly flat on top and not bulged or swelling or leaking anything. Make sure you look under the fan shroud. Most of the bad ones had either a plus + or X on the top - depending on your interpretation. There are a few companies that will repair broken capacitor issues. If it has recently gone out of warranty you could try to contact DELL to see if they will ship you another one. I was able to get them to fix a couple of mobos out of warranty, but that was two years ago. To eliminate some other stuff you could remove the memory and disconnect all the power plugs from the drives and then try to start it up. If it does not change the behavior at all (no beeps, no change in flashing lights) then you probably have motherboard or power supply issues. Make sure when disconnecting the memory chips (sticks) that you touch the metal on the inside of the case first to discharge static electricity. If it does change the behavior add 1 component or item back at a time to see what you can find out. Post back with what you find. And remember a bad PSU does not mean no power, just not enough to run the computer. If you change out the PSU, the one that you replace has to have the same or greater output watts?

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.
