Hymn Posted September 17, 2005 Posted September 17, 2005 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!

StephenC Posted September 17, 2005 Posted September 17, 2005 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? Quote Share this post Link to post Share on other sites More sharing options...
StephenC Posted September 17, 2005 Posted September 17, 2005 With the RAM removed, any beeps? Have you tried RAM in another system to rule them out as an issue? Quote Share this post Link to post Share on other sites More sharing options...
Hymn Posted September 17, 2005 Posted September 17, 2005 i havent heard one beep with, with or without memory... i am right now in the process of an 8 hour clear.... i have tried an old PCI videocard, and still no work.. my computer is running on my test bench... its not in a case. and i dont have any other ram to use :- Quote Share this post Link to post Share on other sites More sharing options...
StephenC Posted September 17, 2005 Posted September 17, 2005 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. Quote Share this post Link to post Share on other sites More sharing options...
soundx98 Posted September 17, 2005 Posted September 17, 2005 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.

Hymn Posted September 20, 2005 Posted September 20, 2005 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 Quote Share this post Link to post Share on other sites More sharing options...

StephenC Posted September 21, 2005 Posted September 21, 2005 I would take the 2100 from the emachine and try it on the your nf4. To see if you can at least get it to post. Quote Share this post Link to post Share on other sites More sharing options...
Hymn Posted September 21, 2005 Posted September 21, 2005 i cant really try that now... can i try and boot my comp without ram and CPU? i NEED to know this so i can see if i can powerup my board and get it past 4 leds or so.
