Yank all cards except video and then pull video and memory and clean the contacts with a pencil eraser (rub down, not across) and then follow with a Q-Tip dipped in alcohol. Reseat Video and memory. Clear CMOS and try starting tapping the DEL key (most machines its DEL - look at the screen on startup to get into SETUP). Once in BIOS, set for defaults and F10 out. Post back.

Good chance its the PSU - pretty common for them to roll over and die. You can get a cheap - make that inexpensive - replacement at NewEgg.com or ComputerGeeks.com

if you read the orrigional post it said i changed it with several working tested powers suppies it's not the pcu
the thing is ive never had to mess with mother board problems could this be caused by that battery on it being dead or some thing
Edit:oops i guess i put power sources down on accident i ment to put supplies

You may need a micro ATX PSU which is a little different than a normal ATX PSU. Micro-ATX provides 4 output voltage rails (+3.3V, +5V, +12V, and -12V). ATX provides 5 output voltage rails (+3.3V, +5V, +12V, -5V, and –12V.)
Can you give us any other known history on this box. When is the last time it was known to be working?

What PSU's did you test it with? Specs please.
And would you be kind enough to tell me how you went about clearing CMOS?

You'll need to test this machine with a micro ATX PSU or test the PSU with a power supply tester to determine whether or not the PSU is a problem. I don't know how I can make this any clearer.

Based upon your description this is where I would start your troubleshooting. You can argue all you want and if someone else wants to take another approach, thats their perogative. I'm not going to waste your time going through instructions on clearing CMOS and resetting your machine until the PSU issue can be put to bed.

If you are in doubt re: what I've said - why don't you try that power supply in a known good working machine and share your experiences with us.

:tazz:

edit: "that" power supply being the one that was/is in the eMachine. ie: the original micro ATX

i know my pcu is good be cause i connected it to my slightly older computer that works and the pcu turned it on but it wont get the other one to work i think it's the mobo but is there a way to fix a problem like this without telling my friend he'll need a 150$+ mother board if he wants this thing to work again?

my biggest susspicion is that his mom told me it made a horrid noise when it failed could it be the central prossesing unit?is there a way to tell which is the culprit?
and sorry if i appeared to combating you i was trying to say that i had already run the working pc well off of the pcus i was useing to try and run the broken computer. also like i said i can't get far enough to work with the cmos like i said the last noise it ever made was thatannoying buzz or beep what ever it is im tring to be as much help as i can

oh and you keep mentioning cmos is there a way to clear that with no power? like i said ive never had to deal with anything major on a mother board before

The best thing you could do for your friend is to advise him that he needs to take this to a shop with a qualified technician.
