my workstation was working fine, but does not boot anymore.
All i get is a black screen, no bios, no post, and only the diagnostic lights 3 and 4.
I looked in the manual, but this light combination isn't mentioned anywhere.
I tried to remove and put back in everything (cpu, ram, all pover cables, vga)
but nothing changes.
Only removing the ram gives me light no 1 and some beeps (memory not recognized)
I also bought some replacement memory directly from Dell (FB-DIMMS DDR2 667 ECC), but same issue.
What shoud i do?
Any help appreciated
Remove the hard drive and test the ram one stick at a time.
You are not even getting POST.

I have had the same problem, just LEDs 3 & 4 showing green. Then I replaced the RTC-Battery on the motherboard and everything worked fine again.
