No Boot, 4 LEDs, Needs Help!

Recommended Posts

Recently my board got burnt out by my accidental rewireing of my PSU during the process of sleeving. I RMAed the board to newegg and i recieved a new one today. I am not sure if when my board got shorted out originally, it shorted out the videocard, memory, or processor.

 

Tonight, i plugged in the VERY minimal connections to my motherboard to be cautious.

 

First i tried powering up with Memory (two times, once yellow, once orange), CPU with heatsink and fan, and videocard. and hooked up only my mouse, keyboard, and monitor.

 

I powered on the motherboard... all my fans turned on, but the 4 diagnostic leds stayed lit. Nothing happend at all. Nothing on the screen, nothing anywhere. THE 4 RED DIAGNOSTIC LEDS STAYED LIT, AND NOTHING HAPPENED.

 

Ive tried removing components one by one, without videocard, without memory, without this and that, ive tried 1 stick of memory (both sticks seperately).... everything i could have imagined that could help.

 

I am so lost, i want to get my computer to work so badly. Someone please help me out!

 

Is my cpu gone? Memory gone? both of those gone? I dont know about my videocard.... someone help me please!

Ok, is your motherboard in or out of case. Also my want to try the longer cmos clear. Do you have other RAM hanging around? An old PCI video card?

If your ram tests good in another system, and the long cmos clear does not do it. And this is the second dfi nf4 motherboard. Looking like your CPU is the issue.

So this is the same PSU that was involved in the 1st Problem?

Are you sure the PSU was not damaged?

Positive that it is now wired correctly?

Have you tested the voltages with a MultiMeter?

 

Sure sounds like a PSU that can't deliever enough current to me.

yeah, yeah I know it sounds like the old blame the PSU rap but it could have been damaged in the 1st Mishap.

 

Any pins damaged when you removed it from the 1st board. I know they like to stick to that XP-90. So many variables here when you consider what happened to the 1st rig. Talk to us about the PSU.

ok sorry it took me so long to respond, but i finally got the time right when i got home from school.

 

i tested my PSU as jumpstarted with a digital LCD multimeter.

 

i tested the following wires from the 24 pin connector, as tested, my results:

 

12V = 12.16V

5V = 5.11V

3.3V = 3.36V

-12V = -12.01V

 

On the 4 pin (P4) connector, i tested for assurance, i also got:

 

P4 (12V, 4 pin connector) = 12.16V

 

i think my CPU is dead? not sure about the memory.... i have an old emachines T1842, which is the only computer in the house i could possibly try things on, i am wondering if my T1842 will support PC3200... currently it has only PC2100 in it.

 

will it work? i DO NOT WANT TO TAKE ANY CHANCE of breaking that computer.

 

is it safe to try my ram on that computer?

 

those are my voltages... now is it my CPU? ive tried booting with and without ram, one stick or both, still no go... so this is possibly a CPU issue ide guess?

 

would it be SAFE to boot up without a CPU and see if the computer will turnon or not, to decypher if the problem is the CPU, or is that a risk of breaking the board?

 

please help me out guys,

 

Tom
