Welcome to the Dell Forums
Your problem sounds like a motherboard issue but we will need to do a bit more troubleshooting to help you determine what is broke. So lets start here
1. when you power on the system look at the condition of the light in the power for color and wether it is flashing or not
2. Check the diagnostic lights. allow the system a min to let them possibley stablize as the will go through a sequence as the system attempts to boot up The lights are on the front panel See HERE for mor info.
3. Listen for any beeps and if so try to hear the patteren that info is in the same as the previous link.
Report back with the finding and we will provide further assistance.
Oh an just for your info, Typing in all caps on a forum is considered the same a yelling.

Can be possibly memory. Try pulling all memory out and then place one stick in the slot closest to the processor see how it boots. remove that stick and repeat with the other untill all memory has been tested. if no change, inspect the motherboard capacitors. look for leaking caps,bulging caps.
Try doing a CMOS reset

Hi Dave,
How exactly do I do a CMOS reset? Is it as simple as removing the battery and replacing it?
I'm sorry to jump in here but it sounds like limikee is having the same problem that I am and I was lookin' for more advice.
Here is what I posted
My E510 gets hung up on the DELL screen.
When I click on F2 or F12 it doesn't work.
The screen displays: The Blue DELL logo, DELL DM051 Series, BIOS Revision A07 and the Intel logo.
The hard drive symbol, 1 and 4 lights stay on once it cycles through all the lights (1 thru 4) but then the hard drive symbol light shuts off leaving only light numbers 1 and 4 on.
No beeps.
Someone replied and here is there suggestion and my comments.
The 1 and 4 lights that you mention are not included in the diagnostics page for your system. Uh-oh
This usually suggests a motherboard or CPU problem. Uh-oh But you can start by unplugging the system ... Check
unplug and reconnect every cable in the system. Check
Remove and then reseat every card that is installed. Check
Remove and replace all the memory. Check
When inside, I suggest that you use a can of computer grade commpressed air to completly clean out the system. Hold the fan blades while you spray then to prevent them from over spinning and killing the fan. Check
I even went as far as removing the processor and cmos battery. About the only change that took place is that now when I hit the F2 key the dell screen says entering setup...but it doesn't.
Do yoo have any other ideas Dave?

CMOS RESET. this involves a jumper on the motherboard Item # 30 <ADMIN NOTE: Broken link has been removed from this post by Dell>
1 and 4 light not being shown in the diagnostic light listing will usually indicate a motherboard issue.
So you reseated all the above. I suggest now you remove all the cards, remove all the ram, unplug the power going to the drives. press the power button note color/condition of power button light, look at diagnostic lights.
you should have hopefully a different light code. if it is still the same the motherboard is gone. See HERE for some links to replacement boards, you can also get tone at Dell Spare Parts
