Need help Asus P5LP-LE. Please.

post #1 of 33
Thread Starter 
I have a few questions. I have this motherboard from a Wal-Mart bought Compaq. Here is its specs. I bought a new case and psu. So i can use my 8800GT. The new PSU has different connectors on end of all front tuff. The old case/psu had one connector for front usb, 1 connector for front audio, and 1 connector for front power. The new one has the following.

power button - 2 prong plug.
power led - power +, power -
hdd led - hdd +, hdd -
reset button - 2 prong plug
What goes where? How do I know which is positive or negative?

the mobo has a 24 pin connector.
the old psu was only 20.
the new psu is 20+4-should i use 20 or all 24?

When i wired everything up last night, I plugged in, and hit power. All fans and lights come on for a split second then power down, and that is it. If I unplug and wait a few secs then plug back in I get same result.

On the board at bottom right is the power button area. It does not show a +/-. Just says power button, reset button, power led, and hdd led. How can I figure out which is positive or negative.
Thanks for any and all help.

Where the power button area is, you can just plug in the switches it doesn't matter whether the polarity is right. With the LEDs it does but some trial and error will help you there, plug them in, if they don't work flip them upside down and try again. Also use the full 24 pin if you can. Finally do you have the 4-pin/8-pin P4 cable plugged in as well.

Yes. I have the 4 pin plugged in like it was on the other board. I think it is for the chipset? Right?
Why wont the computer come on? When i hit power seems like everything comes on briefly then shuts down? Like a split second. Maybe a grounding problem. This is my first build. I wonder. Does the MB have some kind of isolater behind it, between it and the frame? Thanks for help.

It sits on brass standoffs that you have to screw into the motherboard tray. You could try taking the mobo out, placing it on a piece of cardboard with just barebones connected. Also try turning on the pc using a screwdriver or other metal object and briefly shorting the PW_SW pins.

I don't remember brass standoffs in my old case, nor were there any in the hardware kit with the new case. I will check into it. Thanks alot. I am not ready to start overclocking, yet. I am a gamer. Just seems like this site was best to get some help. I really appreciate it.

Did the mobo sit on raised 'dimples' in the motherboard tray or maybe plastic pegs, they are all possibilities. But the bottom of the motherboard should NOT be in contact with the metal mobo-tray.

Ahh ok. If the bottom is touching the metal, will it burn up the mobo, or just short it out? I hope that I did not ruin my mobo. I installed it right into the case. The back is probably touching the metal case. I will see in a few mins. when I go home for lunch and try to redo.

Well, it may have caused damage, but loads of people on here have not caused damage doing the same thing. You'll have to hope for the best, but as long as you didn't see smoke or smell burning you probably got away with it. Let us know how you get on

Standoffs usually look like this -

Now that I think about it, there were some plastic peg things in a little bag. That must have been what they were for. LOL.
