537s Inspiron desktop won't turn on

This question is not answered

Hello,

Asking for you input on how i can get my desktop to work again.  The green light for the power supply in the back turns on when plugged.  I see a blinking light on the power button and sd card reader but it won't turn on when the power button is pushed.  When the computer was still working,  the fan( don't know which one) would turn on very loud .  I had to get rid of some applications for the fan noise to stop or quiet down.   I would also get a pop- up from the right side bottom of my computer saying something like it's being over worked or too much ram usage.

I did the following:

Used another power plug but no go. Unplugged all and pushed the power button for 10 sec then plugged back in - no go.

Your input will be greatly appreciated.

    Does the power supply fan run/work?

    What colour is the blinking power button light?

    Are there any 'Beeps'?

  • thanks for the response.  No noise from computer at all. Just the light power supply, sd card, and  about 10 secs, very weak, green blinking  light on the power button.

    Do any of the fans work, eg power supply and case fans?

    A blinking green power button light, is not a listed code.

    There are no 'Beeps'?

  • i just read the manual.  i will need to plug the speakers to hear the beep cause i only have the power plug plugged on.

    I did remove the computer cover and  no fan was working.

    Does the power supply fan work?

    Best to connect the speakers, because the "Beeps' gives a troubleshooting code and if there are no 'Beeps' it could indicate a motherboard issue.

  • Yeah no beep at all with speakers on.

     Try the following, if you are comfortable working around computers:

    Note: The only 100% method of testing a PSU, is to install a known working power supply.

    Unplug the cord from the power supply, hold the power button in for about 15/20 seconds, open the case, unplug the 24-pin power connector from the motherboard and jump the Green wire to one of the Black wires, reconnect the power cord and power the system, if power supply and case fans and the hard drive run, then the PSU should be good.

    Note: Do not remove any wires from the plug, use a small piece of wire or a paper clip as a jumper.

    Power supply checks out, again disconnect the power cord, hold the power button in for several seconds to discharge the residue power, reconnect the 24-pin connector to the motherboard.

    Remove all PCI cards from the system, take out the video card [if applicable], disconnect all peripherals, except the monitor, mouse and keyboard and disconnect the power & data cables from all drives. 

    Reconnect the power cord and power system on, see if you get a different LED indication on the power button, or 'Beeps'.
    No difference, remove the memory from the system and try again.

    Still shows no signs of life then you are looking at a motherboard replacement & maybe a processor. 

    Note: The processor rarely fails and the only method I know of checking a processor, is to install it a compatible working PC, or use a known working processor.

  • Hi, I replaced the motherboard but didn't work still. Now I'm not sure when I tested the old one that the cpu fan worked because now it's now not working. I think I kind broke it because of the air gun that I used. The fan was spinning when I did the air blow gun to remove the dust. Also, is it necessary to put a thermal glue or paste on the fan and cpu cover? thanks, art
  • Check for bad caps on the main board and in the power supply. 

  • Bad caps are a very common problem in Dell computers.

  • In general no power means power supply long before main board. Also a good visual inspection usually will turn up a suspect in any repair. Not always but most of the time it will. In the case of the power supply you have to remove the cover to do an inspection.

  • I would not follow that advice in any form. No power think power supply first and foremost. 

  • Did the two tests below after replacing the motherboard and still did not work. I also noticed the CPU fan did work when I did the jumper test. Would the CPU fan broken then?
