Hello

So for clarification…it will not power up or it will not boot up? The 1 & 2 light what color are these?

[veeg]

It seems that if the power button is blinking amber,this would indicate that your power supply is failing.

Thanks Vger for coming back so fast. when I push the power button the blinking starts.all the list are amber. the DVD drive start recycling. I have 5 amber blinking lights DVD drive door, power button,LAN indicator light, Diagnostic light #4&5 Diagnostic light #1&2 are on and are also amber. Parts are available but so is a replacement computer.

You are welcome.. Here is a link for a new power supply,if you wish to go in this direction.. Amazon.com

Before you buy anything ,that is unless it is a new pc… I will re check my research to make sure this may be the issue.

Vger I have a up date disconnected all power cables and ribbons cleaned all connections removed power supply cleaned fan. reinstalled hard drive reconnected all cables and ribbons. connected power. Now I have blinking green DVD dvd light green power button light, Blinking green, LAN indicator light # 1,2 and 3 #4 LAN light on green. There is a symbol of some kind top of LAN panel can not make out what it is. Am I right being the lights are now all green I can rule out a bad power supply? Thanks for your patients James

Ok let me check on that..

[veeg]

Ok it could be in power saving mode now..press the power button or move the mouse around and or press any key.

Also it may be a good idea to change out the cmos battery as (I read this is an issue in some Dell’s when the cmos battery is died/failing)..
!. Before changing out the cmos battery -unplug the pc ,hold the power button down for at least 30 secs or longer,make sure all the mobo lights are out when doing this.
2.replace cmos battery…power up and test..

Vger have to put mi project on hold have a plane to catch. Ill change the battery when i get back next week Ill let you know if all is well. James

[veeg]

Ok..no problems.. (Pending)

[orf1]

Vger back in town after trip from hell. replaced the cr2032 battery and installed new hard drive.still have the same problem. all lights are green with DVD tray light blinking ever 2 seconds power light not blinking, diagnostic 4 on and not blinking, diagnostic light 1 and 2 bringing ever 1 seconds diagnostic 3 blinking ever 2 seconds. Im surely over my head with this and don’t know where to turn . Thanks for your help. James

[veeg]

Hmm.. do you get any beep codes?

[orf1]

no beep codes. The DVD tray sounds like it is trying to recycle the door does not open however. Ive tried unplugging the hard drive did not help. do you think unplugging each component one at a time less the mother board help find the bad component? James

The DVD tray sounds like it is trying to recycle the door does not open however.

Hope you don`t mind the interjection folks

James,

Does your DVD drive have a small pin hole on the front of it where you can insert a straightened out paperclip, if yes, give it a try and see if the drive tray can be manually opened, alternatively disconnect the DVD drive from the PSU and MB in case a bad optical drive is causing the POST to fail.

In both instances please make sure that the computer is isolated from the mains power first.
