Power supply is ok (tested twice in stand alone method), on board green LED lit as i plug in power supply to AC outlet but no light came out from power LED, HDD LED, and then tried switching the front panel button but no reaction after that just the green LED (on board) are lighting.

- First thank you very much pin_0018... :)

This is what really happened. I got usual black screen with my PC until i had enough. I opened the casing then saw the aluminum heat sink on top of a embedded chipset MOBO (location: in between of processor and AGP slot). Somekind of 2 butterfly arms/clip attached to the aluminum heat sink that firms the position of the heat sink. those clips has 4 "U-type clamps" that solded to the board. 2 of them I found were dettached. 1 missing 1 recovered. I pull out the MOBO from casing then removed/dettached P1 plug, video card & other card attached to PCI slots retaining the processor and the memory. I started bending 1 copper wire same shape as 1 recovered "U-type clamps" to replace the missing one then re-soldered it. After the trouble i returned all cards as it is. I plug in AC, the usual green LED lit up (knowing everything's fine) then i push the front button swicth and there's no reaction after that. I eve try checking the power supply by stand alone method. jumper the green wire to adjuscent black then then pun a load of chassis fan and it runs.... so meaning the power supply is in good condition. I been doing checks for 3 days now and still no progress. Please help me revive my asus P4XP-X no bad capacitors were replced during the re-solding of clamps.

- If ever you want to see the MOBO pic check this site http://www.baber.com/motherboards/asus/asus_p4xp-x.htm the chipset with an aluminum heat sink is the in silver almost in the middle of the mother board. All I did was provide and re-soldered existing clamp to return firmly the popped aluminum heat sink. Thanks need your expertise.

- i don't think so..... I clean the back surface of mobo by brush. What i noticed while the northbridge heat sink was still detached is that thermal paste is already dried up. Should I provide new thermal paste? I'll go check the back foil again.

May 18, 2009

- I just gave myself a break I've been working for this mobo for two weeks already. I'll do what you advice and will keep you posted on any result each steps.

- I'm Still hoping that my MOBO is stil working. Thanks again for your post replies and insights, now I double check the back side of my MOBO's circuit board print (looking for any traces of damage) so far I see none. I provide thermal paste for the north bridge chip and re-attached the heatsink permanently, plug in the 2 power supply plugs to MOBO socket, chasis fan and then the speaker. After plugging it in to AC, the MOBO instantly powered up (the green LED lit).

Results: time started 1:45 pm
1. MOBO green LED - OK
2. CPU fan runs - OK
3. Chasis fan runs - OK
4. Speaker socket - Plugged in (no beep sound)
5. HDD LED socket - Not plugged in
6. Power switch socket - Not plugged in
7. Poer LED socket - Not plugged in
8. Reset switch socket - Not plugged in
9. DDR Memory - Not installed
10. Video Card - Not installed
11. Hard Disk - Not installed
12. Monitor - Not installed

Without item 9 to 11 i should be hearing soe beeps right? how come I receive nothing? North Bridge Heat sink has temp but not as hot as my last post. 2:30 pm my MOBO still running, anyone please help?

01. MOBO green LED - OK

- reisenstein, pgh_pa_guy & pin_0018 thank you guys for the insights and advice I really appreciate it. The hardest thing to accept is that if I repair somebody's MOBO I can easily fix it like the P3 board that i replaced all bulging capacitors (6 months ago), but when it comes to mine nahhh like my friends always say "Sh#t happens". It's hard to find same MOBO (the one i'm working on) here in my place. All I want now is to access the "my documents" folder of my boot HDD from the damaged Asus MOBO. I have spare unit that made the boot HDD as slave. However I can't find the link directory eventhough I tried to reveal or unhide the hidden folders. The computer says I don't have permission to acces the directory of file folder, contact administrator. All I need is to get all the data inside the my doc folder. My HDD is not damaged I can actually see other folder and open it except accessing the My Documents folder. Please help anyone?

- "Log on to the machine using the same log in you used when that drive was the boot drive."

You mean that I'll change the log in/user name or the computer name name from the spare CPU? Then using the old boot disc providing a jumper as slave then I can access the file inside?

Jun 01, 2009

- "change the user name to try logging in as the old user to gat at the data. The drive must be configured as a slave and it should work.

Ok the spare unit I'm referring to is too far from me right now and it's almost midnight here. I have here now is a laptop of mine i have an external box that will the existing boot drive. If this is possible my next question is I'm using Vista for this laptop and I used XP pro from the existing boot drive will this be possible? Thanks again reisentein.

Jun 01, 2009

- Cool thanks reisentein, I might do this tomorrow my eyes are heavy now. I'll take note on all of your advice.
One more thing I kinda "forgot" the previous log in name i used on the old boot drive, is there a way i might see it again? Its been or almost a month since I never used the old drive.... don't worry i didn't use any password during start up or log on password just clicking the icon.

Jun 01, 2009

- :) Thank you Sir I really appreciate all the help, thanks for your time hoping for future... problems :) cheers to a hero. see you soon

Posted by reisenstein on May 21, 2009

If the computer did not boot up and you KNOW that the power button is plugged in correctly...You probably damaged the board when you soldered it.

Posted by pin_0018 on May 16, 2009

Nop that thermal paste has got nothing to do with the issue.Wel check ur moniter(do a selftest on it).try runnin ur system with out the HDD/DVD Rom.try if ur system is able to Show the Bios page.ie run ur system using ram/pron ur mobo nothing Else Connect to ur system.if nothing Happens run ur system without ram.Do let me knw the Result.

You've now spent more time than this board will cost. Replace it...move on.

Either the board was damaged during the repair attempt, or was bad to begin with. The original problem description (black screen) sounds like typical mobo "no boot" trouble. The loose heatsink on the chip may have contributed to the failure, or it may have been simply coincidence. Given the low cost of motherboards, it's silly to spend any more time on attempting to diagnose and repair a problem. Just replace the board and move on.
