P5NT won't boot

Mobo will not POST. I do not grt a POST beep. Tried clearing CMOS (number of times). I think I need a new BIOS chip. When I turn on the system the green pwr lght on the mobo lights & I hear the HD actuator activate. The HD access light stays lit. Other than that... nothing.

    I disconnected the HDD, pulled out the memory & removed the video card. Nothing attached other than power & CPU to the mobo. same simptoms... no change. The issue started when I was messing with the BIOS setting to oc the FSB & memory. Memory is OCZ SLI ready 1066 Mhz (2Gb). I set the FSB & mem both to operate at 1333Mhz (I thought anyway). Machine POST by didn't boot. I was able to get back into the BIOS & set the FSB & mem back to 1066Mhz but then my problem began & nothing seems to change the simptoms. I am trying to get a new BIOS chip from ASUS. If that doesn't work, and I am not doing something wrong, then I will have to RMA the board.

    Bios crashed wen i tried to oc. P5n-t deluxe model. Get no POST beep although the power light is on. reset cmos,, doesnthelp. What do i do?

    Much the same problem, long story:
    MB was working fine for 7 months until I noticed SLI was not functioning. Tried BIOS upgrade etc. - no joy, the system only recognized one video card. I eventually RMA'd board.

    Got the same serial numbered MB back and it would not POST. I sometimes could get into CMOS setup, but it would lock up hard. Single RAM stick, single video card, would not POST. RMA'd board again.

    Got the same board/serial number back and it still wouldn't work, with the same symptoms, so I bought a new CPU. Same problem. Bought a new cheap MSI MB. All of my gear worked fine on the MSI board. Oh, and by the way, I couldn't use that new CPU I bought according to ASUS b/c my BIOS was too old. That's hilarious guys, I sent it back to you with a newer version than you returned it to me with. WTF?
    ASUS had me send my GPU, my RAM, and my CPU back on the final RMA. That's right, my stuff. I sent one GPU, CPU and 2 sticks of RAM and used the MSI board in the meantime with the remaining peripherals.

    They sent me back a P5-NT Deluxe MB different serial number. All the gear works fine, the BIOS is 1303 (Oct-2008).

    Seems to me that ASUS has a bad batch of these boards floating around. My greatest problems with them was resending me the same serial number motherboard back 2x, and downgrading the BIOS. Evidently they could not recreate the issue with their own gear. This whole fiasco took 2 and a half months to resolve and probably lowered my lifespan by 6 months.
    Again, the new board works fine now.
    So, if you RMA, see if you can get a new MB shipped and verify it by serial number. That's my two cents. Good luck.
    And ASUS? I truly hope you're reading this. I won't be purchasing any of your products ever again, for anything, not even a mouse pad.

    Try booting with no memory in it and no HDD connected and post results here.

I had the same problem; I had to turn it on and off about 10-15 times to get it to boot. It seems to have been caused by my USB keyboard and mouse. So I removed the "Removable storage" from the boot menu, in the BIOS settings and it works fine now.

Posted on Sep 15, 2008

It turns out that the BIOS was corrupted somehow.I contacted ASUS & worked with a tech who was ready to RMA the motherboard but I asked that they send me a BIOS chip first so that we could try that before we RMA the board. I got the chip yesterday. I repleased the old version 1001 BIOS chip with the new version (news flash! New BIOS a/o 6/10/2008) 1104 BIOS updated chip. Walla! I GOT POST! Of course the machine had no memeory, HDD or vid card attached so I put it back together & I am up & running!

System: CPU Q6600 MEM 4GB Vid 9800 GTX HDD WD 500Gb

Have you tried clearing the CMOS by removing the battery with PSU off and then shorting the 'reset cmos" (or similar) pins on mobo?

Also found this on the ASUS web site under the specs for the P5NT WS board...

P5NT won't boot - 01.gif ASUS CrashFree BIOS 2
The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support DVD. Users can reboot their system through the support DVD when a bootable disk is not available, and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

Have you tried this?

    Just another thought....

    Does the PC seek the FDD or CD when it tries to boot? If so you may be able to recover bios by d/l the BIOS and either the DOS tool or the Phoenix Award BIOS flash tool and writing them to a disk to boot from.

    Look HERE and select BIOS and/or BIOS Utils for the available versions


    I corrupted the BIOS on my Gyigabyte boatd and could not even boot off floppy to recover bios.

    I read somewhere that where the BIOS is corrupt and wont even seek the FDD, you can force it to do so by shorting the datalines out. This causes some sort of internal check to fail and initiates a FDD seek. I did this and was able to rewrite my BIOS and recover a working MoBo.

    ***WARNING*** you MUST ensure you know what you are doing so you ONLY short DATA lines. You need to determine whatthe BIOS chip is and get the datasheet for it to even attempt this. If you short any other signal or power it will not work and may DAMAGE your board permenantly !!!!!

    Oh and if you manage tio get into BIOS make sure the FIRTS thing you do is select the "default" or "optimised" settings and save/reboot before trying anything else

Asus P5NT motherboard - will not boot to bios

The voltage output onto the three main rails as you put it is 12 volts and 5 volts. As you say that there is no beeping, you must be getting power lights and fan spin up. This would indicate a failed graphics card. I may am only going on the information you have supplied. Although if there is no lights or fans it may be a failed psu. You also don't identify your PSU. if you have the one that came with the tower, it isn't surprising.

Probably your BIOS battery, replace that and setup you BIOS again and it should be fine. BIOS batteries look like little round watch batteries.
