ASUS P5LD2 won't boot + No BIOS beep or video signal

I am having similar issues, no post, just one never ending beep. Power supply, ram etc all tested and good.

ASUS P5LD2
Pentinum 805 D 2.66Ghz

I have gone to the ASUS website and found the following link



I entered P5LD2 and found that this processor is only supported after BIOS 0901. So I will be going home and checking the BIOS version on the box (if it has one). If lower looks like I be hitting up some friends or the local computer shop for a older cpu loaner..

I'll report on sucess or failure.

cheers

Same problem!

Hi there folks, any updates as to whether the new Bios fixed the problem?

I have been reading this thread in interest as exactly the same thing has happened to me, im currently rocking

ASUS P5LD2 (normal edition)
P4 -3.2G EMT64
512 - Samsung 4200 DDR2
40GB Seagate IDE
16x Liteon DVDRW
Radeon X800XT
Ultra X-Connect 550w PSU (20pin only)

My system turns on and runs some checks for a few seconds and then promptly turns off, I cant even get into BIOS before it goes.

I have systematically gone through and checked all of the components apart from the PSU, the RAM (although im pretty sure it is ok), the CPU and the Video Card (although it must be working else i wouldnt get no picture!)

so yeah, im going to go and upgrade the BIOS in the weekend and see how it works...

hi fernz

As I said in my last post I upgraded the bios using another chip and my system has been running sweet as since.

Down load the latest bios and use the inbuilt flash utility. You con't have to get into the bios to use it. Seeing as when you turn it on it does some checking then it must be going into post initially and as such you can use the altF2 key

If all else fails it is probably the bios or else a dud chip.

cheers man, i just hope that i will be able to get it to post for long enough so i can EZFlash it!

Hello all!

I'm having the same problem with an ASUS P5LD2-MQ which came in an ASUS V2-PH1 barebone system. These are the specs:

ASUS P5LD2-MQ MoBo
Intel P4 541 3.2GHz
1GB DDR2/667 Corsair
160GB SATAII Maxtor HDD
Sony DVDRW
OEM power supply 350W
*no PCI peripherals installed

It all worked fine for the first week, I installed Windows, updated BIOS, driveres, etc. Then all of a sudden, during startup it showed the ASUS splash screen druning POST and then in went black, and I havent been able to boot up scince. I get no beeps, no HDD activity, DVDRW light stays on, fans work. I already swapped and checked the CPU, PSU and RAM, they all work with other PCs. I tried CMOS reset with no results, i tried switching the RAM to different DIMM slots with no results. I even reassembled the whole thing from the ground up and got nowhere.

Has anyone else had success?

My problem is weird because the system worked fine before and now it doesn't, while the other people here have not been able to boot up from the beggining.

yeah, im not sure that you are having the same problem as other people here have had. I guess since you updated to the latest bios, then that musnt be the problem... sorry im not much help

There lies my problem, my PC won't post and I cant enter bios to change anything. When I turn it on the fans run but there are no beeps nor HDD activity and the monitor stays in standby.

If you have no beep, it sounds like you havent connected both power leads to the Motherboard or you have a faulty Power Supply

Thanks for the help everyone, but my motherboard did get damaged due to a faulty power supply. I sent it back to ASUS even after the warranty expired, they were nice enough to not charge for repair services (I only paid shipping). I got it back with a replaced power supply and my repaired motherboard, it's been working fine ever since.

I'm sure that several things ie. power, ram etc. can cause a similar problem, but in my experience, this has only ever happened to me when the motherboard didn't support the specific cpu installed. This issue was always resolved by flashing the bios with the latest version.
Hope that helps some of you. Good luck.

Same as Everybody Encounter this Problem...

I have the same problem arises when I assemble a newly purchased Motherboard "ASUS!!!!" This is my third times to assemble a computer but this one is the very tough one, cause it almost half a month when I started configuring the problems that I encountered. Maybe this "P5LD2" is the most worse nightmare of ASUSTEK company. I've tried all the possible solution to make this things worked but still !!!!! A failure on my part...

Dear friends!
Thank you so much for your posts !!!
I spent 5 hours to try to start my ASUS Pq5 PRO - no results... - no picture, no beep, only fan working. But I felt motherboard good (I have this mistery... ).
I was so pity (and angry - a mess with UPS boxes in my kitchen, wife looke at me like I am looser).
And I went to Internet and dial "asus p5q doesn't boot vga" in Google... - and find this forum !
I red everything and dissolved my problem!

One main problem - not right power connection ! (if Power Supply good)...
I connected 24 pin power connector (below DDR2). My power supply has configuration 20 connectors and 4 connectors on the same wire. I gathered them together and put it in 24 slot. System did not work.
I have in my pover Supply else 6 connectos and 2 connecors on the same wire. I took out cover from ATX power connection {don't do it !!!} (4 was blocked in Factoty) and put all 8 connectors together. Even fans stop working. I was afraid that burned motherboard...
And I found on my Pover Supply 4 connectors on wire - I put back manufacture cover (block 4 connectors) and connect to the boottom 4 pins.
Moterboard start beeping! (BECAUSE NO EVEN MEMORY WAS IN MY CONFIGURATION - only keyboard and videocard).
I put 1 GiG memory stick and my black screen after 30 seconds start to see BIOS !!!

Thank you all my dears!
Good luck!
