Either the power supply has failed or the power cable is not getting power to the board (if the lights are amber). Check that the power cable from the power supply to the motherboard is fully seated. You may need to replace the power supply - you will need one that will fit your case and matches the various devices and plugs that you currently have. (20+4 pin for the motherboard gives the most flexibility, additional power for the CPU (4 pin or 8 pin), SATA if you have SATA devices, regular 4 pin peripherals for IDE hard drives and optical drives, 4 pin floppy, video card (if you have a PCIe card that needs a 6 pin plug), etc.)

I hope this helps.

How can I fix DELL precision 490 issue

Ersin, not knowing the age of the unit and the motherboard condition, is hard to make a problem fix.

If the unit is two or more years old, I would examine the motherboard for Bad Capacitors.

If the caps are not crowned or bloated, try the next step.
Remove all external devices and check the fallowing.
USB Ports for shorts
CMOS Battery for 3.0 volts
Remove and reseat the memory and CPU ( Reseal with Thermal )
Check all your cooling fans
Remove and test the power supply. ( Do this First )

When testing the unit, make sure all external devices are disconnected.
Hope this helps.

Dell Precision 490 constant reboot after ghost image completed


I figured out how to ghost a Dell Precision 490 with a 32 bit Windows XP Image! Like you I had the same problem where it would constantly reboot after I imaged it with an existing 490 image. The answer is actually very simple. Boot up your Precision 490 and hit F2 to enter the bios. Select Drives and then SATA Operation, change it to "Raid Autodetect / ATA". Reboot the 490 and re image the machine, it will now work!
