Green power light comes on but disk drive lights keep blinking and my screen is black on my dell dimension 4700


Remove ALL media from the machine DVD, CD, USB, etc. Check/reseat all Monitor cables. Reboot. If that fails, unplug , plug back in in 30 seconds or so. reboot, if you get a Dell Logo, Open the boot Menu and select Boot from HDD first.

What's your problem?a way to turn the SATA ports to ON in the BIOS


You can go into the bios and on those drives that are not found you can turn them OFF or N/A. They are probably set to AUTO or ON.

If that does not work I would say remove the power cord, remove the cover, then remove the main power to the motherboard then plug the main power to the motherboard back it. The main power will run from the power supply and the end of it will be about a 2 inch strip that plugs into the board. Press and hold the little catch on it then pull it out of the socket on the board. Put it back in firmly. Reboot and see what happens.

Have a dell dimension 4700 with orange steady light?


Turn the machine off and unplug the AC power then hold the power button in for about 30 seconds to drain any residual power. Plug it back in and turn it on, when you see the Blue DELL word press CRL+ALT+D and this should run a diagnostic on the hard drive. If it runs ok you will get a pass or fail on the hard drive. If you cannot get the diags to run you might have a bad power supply or motherboad/processor. I would find a known good power supply and try it before the motherboard.

I turned on my Dell Dimension 4700 computer,but the amber light started to blink . I held the start up button for 5 seconds and the light went out. I tried to start it up again and got the same thing,...


Vaughn it sounds like the power supply is going bad, try another known good working power supply. If that doesn't work then the motherboard would need to be replaced. If the power supply isn't giving the correct voltages that could cause the computer not to turn on. If the motheboard isn't able to convert the voltages properly then the motherboard could be faulty.

Dimension 4700 series does not power up??


make sure the power cord is plug in tight, or try another power cord.
make sure the fan at the power supply comes on. if it still doesn't power up, then you need to check the power supply with a voltmeter at the output pins.

No display and wont boot


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Power supply is easier and cheaper to replace.
