Whoops...sorry, I have a Dimension 4600.  I checked the video card seating and the cables to see if they were loose.  Everything seems in order. 

I had thought of pulling the video card and running off of the on board video to see if that might cause the machine to at least show some video messages.  The reason I didn't was because as I sat next to the machine I never heard it access the hard drive either for checking the type, like when the BIOS looks for drives, or like it was booting.  This is what made me think that maybe the CPU got damaged.  I didn't see anything else on the board that might be loose or not connected, like when I pulled the cooling duct off of the CPU I thought that maybe that cable there got pulled off but it is good.

 

Any ideas,

 

Thanks,

You mention an integrated video chip.  Did you by chance vacuum because you were upgrading graphics cards?  If so, you need to disable the integrated video before putting in the new chip or you will not see anything on the screen. 

It came with the Radeon video card and has been working fine for 2 years.  The fan was running faster than normal,  2 speed fan, so I figured that the chip was starting to heat up due to dust.  There was a lot between the fins of the heat sink and in the fan screen. 

 

The other thought that I had was that maybe a jumper from the board may have gotten pulled up into the vacuum.  I am not sure if this board uses jumpers or not.

 

Thanks,

That was interesting but the permutation with my colors was not in the manual.

 

A - Green

B - Yellow

C - Green

D - Green

 

Any ideas as to what error this color combination identifies?

 

Thanks for the tip.

Hi,

 

I tried the memory modules and the PCI cards and no luck.  Although, I didn't try with both cards out because I didn't think that the machine would like that.  But now that I think about it, I should at least get a message on the screen that no memory was detected and the BIOS would load.

 

The B LED is Yellow the second that I push the on button.  It seems like it should take at least a few seconds for it to recognized a problem.

 

Could it be that I fried both memory modules?  Seems kind of odd but maybe.

 

Any other thoughts?

 

Thanks,

Hi,

 

I disconnected all of the peripherals, including ALL of the hard drives.  Everything except the video card and still nothing.  So I pulled the CPU to reseat it.  Everything looked ok, no bent pins.  So I reseated it.  Well, now I don't get any response from the machine except for the green LED at the lower right corner of the mb.  What would cause that problem? 

 

Now I am lost...should I start with a new CPU?  But what did I do that keeps the machine from at least sending power to the HDs?  This is strange.

 

Any help is appreciated.

 

Thanks,
