Why won't my A7N8X Deluxe 2.0 not post

[evident]

confused here... mom calls me at 8PM on sat saying that the computer turns on but doesn't beep!

thinking it was user error, i checked it hte next day and she was right...

The mb still gets power to it (green LED on mb is on when psu is connected to it) but when i push the power button, it does not post or make any beeps. This is a pain in the ass for me to troubleshoot, since I'm scarce of socket A parts. First, i tried flashing the cmos, but nothing happenedstill get power, but no post. I tried sticking in different ram sticks, still get power, but no post.

update: i just swapped PSU's to a psu i had lying around... green LED lights up, fans spin, but does not post!

update2: put the hd connected from that computer on an external enclosure and backed everything up. the HD isn't fried :-D

can anyone give me any clues? I really hope the MB isn't dead
UPDATE 3: PROBLEM SOLVED!!!!
i didnt know replacing the CMOS battery would make it post, but it sure did!!!!
I think it's time to put this thing on ebay and get my parents a laptop anyway, didnt realize how much these things went for!!!


Enermax 350W PSU
AXP-M 2500+ stock
512 MB corsair value PC3200
Radeon X1600XT AGP
WD 160GB IDE HD

if no beeps occurred .. it usually means you have a psu or board related problem....

you've already ruled out the psu.. assuming the 2nd one u tried is ok.....

.. so let's look at the board ...
1) disconnect all of the ide/sata drives.. and any other peripheral... Basically you want to try posting with just a video card and single stick of ram..

2) try reseating the video card ....

3) is the heat sink on the processor sitting correctly ? that could cause a problem, which could prevent the system from posting....

4) if none of these help.. then I would removing the motherboard from the case and try posting with just the video card and memory... to rule out a short between the board and case...

one other option may be to try replacing the cmos battery .. cheap enough to try...

hope this helps

It might be a dead BIOS from my experience and if I remember correctly, lots of nforce2 MB BIOS died even without going into the BIOS. Need BIOS Savior, http://www.ioss.com.tw/web/English/RD1BIOSSavior.html, or hotflash the BIOS, info here: http://www.nforcershq.com/forum/viewtopic.php?t=15104. I never used a BIOS Savior before but I did revive my A7N8X Deluxe with the hotflash method. Hope that helps and good luck.

i'm gonna try getting a new battery... bios savior isn't worth $20, at least for this board.
