Brand new power supply and motherboard i just got replacement with no luck because i am still having the same issue.

Computer goes into Windows XP SP2

*Sometimes goes for a few seconds sometimes for 20+ minutes
any help is greatly appreciated.
*In or out of the case same thing.
*Last night it managed to stay on for 4hours or so.
*Sometimes i get no Video Keyboard or Mouse but i do see the ethernet light on.
*Sometimes it wont even post

-Tried several RAM sticks.
-I unplugged Sata Drive still no post.
-Removed Cmos Battery - shut down after few seconds once ASUS Logo came on
-Placed battery back in slot-Powered on and no mouse keyboard or video
-Tried 1TB sata HDD - still no video mouse or keyboard

i have attached 2 images maybe that could help.

ASUS P5ND20SLI DELUXE
MUSHKIN 650 W POWER SUPPLY
512 RAM -- TESTING PURPOSES
200GB SATA HDD
GEFORCE 6600

when i log onto windows AiBooster tells me the following:
CPU temp is at 36C
RPM = 3013
Voltage 1.42v
PCIE 3.33 v
System 36C
Power 0 RPM
Chassis 0 RPM

Well, I experienced some of the same issues and I see that you replaced the Mb which means you had to lift the processor. Mine was I did not have enough thermal paste. I removed cpu, cleaned everything off and reapplied. Only this time I had too much. Finally I got it just right.

With not enough, computer would shut off on me. With too much the computer would not boot.

Just a thought.

Just some thoughts;

1 Did you clean install windows after swapping boards?
2 You have listed the cpu core voltage and the 3.3 rail voltage however you have not listed the 12V rail. This is the most important rail in your pw supply.
3 Have you run the system in a basic mode; ie with just a single hd and no usb type devices, no scanners, printers, hubs, no add-in cards, etc?

*no its not a clean windows install havent been able to install it since PC shuts off half way through the process sometimes.
*how do i find out my 12V rail voltage?




so heres what ive done so far since the last update;

-applied fresh thermal paste
-tested motherboard outside the case with SATA hdd 1 mem stick still no post or video mouse keyboard
- i am now plugged in directly into the wall
- no USB devices plugged in



ideas are welcomed

You should be able to see all of your voltages in the bios OR if you have installed asus probe. Note if you use asus probe, go to asus's site and download the latest one. The one on your support CD is most likely quite old.

Another option is speedfan. It will display your voltages [along with a lot of other info]

Now, I am not a certified expert, but too much should in no way cause a problem until it heated up and crashed from temps. A cold CPU is a cold CPU and should boot just fine regardless of there being too little, too much, or none at all on it. Granted with none at all it would probably overheat before it finishes POST xD.

Sounds like something wasnt seated properly in this case.

I had this happen just last month.

I tore the tower to pieces, swapping motherboards,
power supplies, CPU's, RAM sticks, and stll the same
problem. Looking at a bare case, I finally realized
what the problem was. Dust had gotten inside the power
switch, and was causing intermittent shutdowns. The power
switch was partially shorted by the buildup of dust.

Live and learn.

ok guys heres an update so i removed the motherboard from the case.

and it stayed on for about 30 minutes or so before shutting down.

one thing i noticed was that the NorthBridge was extremely HOTT. i couldnt even touch it for an instant.


would this cause shutdowns?

[Warning|]

image attached screenshot of HWmonitor.

i just placed a fan ontop of my northbridge. i can actually touch it now.

Can extreme heat on the northbridge cause shutdowns?
cause of so that is my issue right there.

see screenshot.

Yes it sure can...

[Warning|]

ok so the computer shut off on me once more after an hour or so.

all i was doing was listening to online radio.
and doing some google searches.

one thing i noticed was that in HWmonitor TMpin2 was a 127celcius
tmpin0 was at about 40celcius
and tmpin1 was at about 30's celcius

see image

i do not know what TMpin2 represents.

any ideas.

any other program i can use

[crjdriver]

OK, as I posted, use either asus probe OR check your temps and voltages in the bios.

Next I did see in your post the 12V is running @ 11.9V. While this in and of itself is not too bad, that voltage will drop even more when you stress the system. This is another reason why you install asus probe; it can log temp, voltages, etc.

[Warning|]

i will install probe tonight. and post Stats.
PC shut off again but this tie TMpin2 was at 104Celcius

First i would liike to thank all you guys that took some time out to help me with my issue.

turns out i went to BestBuy and just picked up the first video card on site

Geforce 8400 GS

and so far my system hasnt shut off on me since. going for 6+hours "like a normal system suppose to run without interuptions"

im guessing the old video card i had was cauing all the shutdowns and inconsistency in my system.

now my only question is wether i should keep this video card. i am not a gamer i use my computer for basic functions. i have triple display going on now.

i tried searching comparison with my old video card and couldnt find anything to go by. Geforce 6600 256MB.

any further recomendations will be taking iinto consideration


Thanks again.
