Hi guys. i'm new here so i just wanna say THANK YOU for existing. What a site! 
Next, my sincerest apologies if someone has already posted this problem and received a solution. i've been scouring this site and testing all solutions for hours and i'm at a dead end (but due to my tenacious personality am NOT ready to give up just yet!)
Ok, here's the scenario.....
My friend has an old desktop (build date circa 2005) with an ASUS P4S800-MX motherboard with an INTEL psu (though i can't tell you which coz the pc won't boot up). It was running XP and all was apparently fine (this all happened a year ago before i met her) but it had become slow whilst loading pages on the internet. Instead of defragging, clearing temporary files, cookies, history etc, checking with the ISP and doing ping tests, her neighbour decided that all it needed was more ram, a new graphics card and what the hell, lets chuck a second HDD in there while we're at it!
Outcome: a computer that started but was completely unstable. Would totally freeze just doing simple tasks where they had to shut it down via Task Manager. That eventually failed to work so they had no choice but to shut it via the front power button. More and more separate problems arose so the neighbour spent more time 'fixing' it than they could ever using it. Connecting to the internet became virtually impossible. Towards the end of its life, the keyboard apparently failed to work. Frustrated they shut it down via the front power button again and that's the end. It never fired up again.
My resurrection attempts to date:
(Please note that all external equipment used or exchanged in for testing purposes ie. monitors and their cables, keyboard, graphics card, IDE connectors, ram, system speaker, PSU and main power cable are all from my own desktop (an Xaser V Thermaltake gaming tower and mobo. Same circa era, same O/S and ALL have tested and retested during my resurrection attempts and ALL are working perfectly).
ALSO, ALL jumpers, pins and connections have been checked, removed and re-installed using the ASUS User Manual (that i gained online) whilst observing guidance from threads on this site.
Remove the new ram and graphics card. NOTHING. No system beep. No monitor. No mobo LED.
Restore power to mobo (cant remember how. it was a jumper or pin somewhere). LED is lit. PSU is working. Cpu fan works. SiS 661FX Northbridge thing below it warms up. HHD (i've disabled the 2nd non-original HDD) heads are spinning soundlessly. CD drive opens and closes. STILL NO SYSTEM BEEP AND NO MONITOR.
Check for system speaker and exchange for one known to work, connecting and flipping the connection as i go (always powering off and disconnecting the power cord before EVERY change). NO CHANGE.
Remove, recover and reinstall now functioning original HDD (couldn't swap in my own HDD as it only has SATA connections and the ASUS mobo doesn't have this function). NO CHANGE.
Disconnect everything from mobo except psu and cpu fan. NO BEEPS AND NO CHANGE.
Exchange psu for one of the same voltage and known to be working perfectly. NO CHANGE.
Reset CMOS by removing battery, waiting and then re-installing. NO CHANGE.
Reset BIOS (as per directions the mobo's user guide). NO CHANGE.
Reset switch disabled. HDD Led is observed not to be funtioning on front panel despite HDD sounding and feeling fine.HDD Led connectors checked, reversed and reversed again to original setting.NO CHANGE AND STILL NO SYSTEM BEEPS.
Rams removed, switched, swapped. Using original 512 ram only (this ram has NOT been tested on my own tower yet as i've ripped all the guts out of trying to get this mobo to run), i've swapped DIMM connections. NO CHANGE. (original ram is NOT listed in the user guide's Recommended and Tested brands listing but it used to run just fine with it before so i'm assuming all is still ok with it).
Replaced ram with my own of same type (DDR400) and memory. NO CHANGE. Replaced with same type but 1gb of memory. NO CHANGE.
Well i think that's all it though its highly possible that after working nonstop for over 9 hours that i could've omitted a few other tests.
So, if anyone is still here reading this essay, does anyone have any more ideas???
