Help plz

Dell Dimension 3000 desktop.....bleep on startup...1-3-2...back panel code (A-B-C-D)..Green-Yellow-Yellow-Yellow....tried unplug everything just one drive..one memory...mother board and psu .still beeps...check PSU...force jumpstart on PSU and fan runs...change memory stick still does'ntwork...green light on the motherboard....plz help:cry

 

Hmmm, those error codes aren't listed.

Are you sure the memory is fully seated--the clips on either side snap into place?

You could try it with no HD or CDROM connected to see if it boots.

what exactly did you do with the PSU?

Is the power light on the front of the case green?

 

Thanks Sach2 & plodr for ur replies....
@sach2..memory are fully seated...i even tried different memory stick in different panel one by one ...i also tried booting without harddisk and cd/dvd drive(Just Motherboard ..& powersupplY)...same result..i tried to see if my PSU working or not and googled it... and find if i put u shape metal clip on the psu green wire and black wire if PSU is good ....fan run...so i tried that and fan runs......powerlight on the front is green...

@plodr..tried different memory stick one by one in different slot...still doesn't work

 

You may have seen this thread about the 1-3-2 beep code involving incompatible memory.

Was this computer working with this same RAM at some point in the past?

If not, are you sure the RAM is compatible?

 

@sach2 No i am using a same RAM which are working before this problem and even change a RAM with a extra RAM which i had since a long time..they are compatible....but bleeps...btw is there anyway to check the motherboard is working or not?

@estell64..recycling ...that's the last option... which i am saving for later

 

@Halo
