Vostro 200 Slim Won't Post. Is it a bad Power Supply or Motherboard?

I have a Vostro 200 Slim Tower <ADMIN NOTE: Service tag removed per privacy policy>  that is only about a year and a half old and it will not start up or post for me. When I press the power button the processor fan spins constantly at full speed and that continues indefinitely. It just sits there and speeds at high speed but I get nothing on the screen.

-The LED on the Power Supply is solid green

-When I press the power button on the computer, the LED turns off and does not come back on. However the fan on the processor spins at full speed.

-The amber light on the motherboard is lit

-I have disconnected all peripherals and no change

I am thinking it is either a bad motherboard or power supply. I would be greatly appreciative of and input from someone who might know what is wrong with it.

Thank you

Re: Vostro 200 Slim Won't Post. Is it a bad Power Supply or Motherboard?

HERE is the Dell manual's troubleshooting section.  Look it over and see if anything correlates to what you are seeing.

If it's a power supply, the "S" models do not use a standard ATX power supply, they need a custom model.   However, if you have a standard ATX power supply you may be able to rig it up for testing, to eliminate the power supply.

Is your Vostro 200, a Mini Tower, or is it the Slimline version?

Check the reading of the power button LED, is it Steady Blue, Blinking Blue, Steady Amber, Blinking Amber or is it Off?

 Are there any 'Beeps', or error messages, if there are, please post the exact text of the message?

Re: Vostro 200 Slim Won't Post. Is it a bad Power Supply or Motherboard?

Hi Bev,

Thank you for your message.

My vostro 200 is a normal tour (anyway not slim). This is the dimensions of my vostro 200 :

height : 36 cm
depth : 41 cm
width : 17 cm

- When I press the power button, the processor fan spins constantly at full speed and that continues indefinitely.

- The power button led is steady Blue.

- In the begining of the issue, I hade many time a DELL screen of the startup, which is displayed with F2 for setup and F12 boutton for Boot order. Bit it was not possible to enter to the setup. Nothing happens when I press F2 or F12, the machine was not responding. In the meantime, I confirme that the keybord works fine.

- No beeps, no error message... nothing.

- I have disconnected all peripherals and no change.

- The power supply seems to works fine (I didn't try it on another machine), but the power supply on the back of the desktop is steady Green, the Fan, the dvd driver (I can open it) and all others peripherals are powered.

- I tried to unplug/replug the memory stick (i have 4 sticks with 1 Gb each), no change.

- I tried to unplug/replug motherboard battery, no change. I tried another motherbord battery without knowing his condition, but no change.

Any help please?

Thank you very much.

Regards,
NS

Is there a video card installed?

If there is, open the case and remove the card from the PCIe x16 slot and connect the monitor to the integrated VGA connector on the back panel, boot the system and see if this makes a difference.

No difference, then try the following, if you are comfortable working around computers:

Note: The only 100% method of testing a PSU, is to install a know 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's fan 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 remove 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 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.

Bev.

Re: Vostro 200 Slim Won't Post. Is it a bad Power Supply or Motherboard?

Hi Bev,

I have two video card, I tried to use the integrated VGA card with pci card unplugged, but no change.

I removed memory from the mothercard, no change.

I am not sure to undertand what do you mean about "...and jump the Green wire to one of the Black wires...".

Thank you for your help.

"I am not sure to undertand what do you mean about "...and jump the Green wire to one of the Black wires..."

It's to check the power supply, using a 'Jumper' between the Green and Black connectors of the 24-pin plug, allows the PSU to bypass the front panel on/off switch.

Jumping means you use a small lenght of thin wire, [or use a paper clip, bent into the shape of a "U" ] then pushing one end of it into the green wire pin and the other end into a black wire pin, touch the metal inside the plastic housing, to complete the circuit between the two.

Do not pull any wires out of the plug.

Bev.

Hi Bev,

It seems a very special method to check if the PSU is working fine.

But I will try it this night. Il will let you know about the results.

Thank you for your help.

It's because, to check the motherboard for failure, you must have a 'Know' working power supply.
