My dell optiplex gx 620 not displayed when i shart if i power cable put out then put in it's going to working

SOURCE: dell optiplex gx 270 is not giving display

If you are not getting display for your Dell Optiplex GX 270, the issue may be one of three possible causes:

* The VGA cable connection between the Dell PC and the monitor, may not be seated in the VGA port correctly. To resolve this, just make sure the VGA cable is seated completely in the VGA port of the Dell computer and that also the Power cord from the monitor to the power source (i.e wall socket, power strip, surge protector, etc.) is seated securely.

* There may be an issue with the Video card in the Dell PC

* Or there may be an issue with the motherboard for this model of Dell.

To check to determine if the latter is what you are experiencing with this issue, please feel free to review this Dell Support link: Dell Optiplex GX 270 Display issue.

First put your Windows CD in the drive.

While booting, the screen should offer you a couple of choices - Enter "Setup" and tell you which keys to press or "Boot Options" and again which key to select.

Try Boot options first, and choose to boot from CD. It will revert next time you boot.

If you choose or have to enter "Setup" . Usually achieved by pressing the "Delete" or "F2" key look for and change your boot options to select you CD drive first but make sure you put it back later.

You may have to re-boot a couple of times to find the commands I mention, they do flash through fairly quickly.

Open up the computer and clean the dust out of the fan and processor heat sink. If it is a temperature-controlled variable speed fan, it will probably not have to work so hard to keep the processor cool.

If it is a fixed-speed fan, it may be getting loud because the bearings are wearing out. Gently try to rock the fan blade unit - it should not have any wobble or slop in the bearings, and it should rotate easily.

If necessary, clean as much dust as you can out of the power supply without taking it apart.

Do not use a regular vacuum cleaner to **** dust off the motherboard. The high-velocity airflow may generate electrostatic charges that can damage the board. It's probably OK to vacuum out the heat sink if you hold the fan still to keep the vacuum cleaner from over-speeding it.
