mini hp

[Imon Fyre]

hey all.. heres whats wrong with this comp that came in today...

its a little itty bitty hp celeron 700 w/ 128 mb of ram, and the stupid thing will not post...

it will power up, i can hear the hd come on and can see the cpu fan doin its thang, but it will not post!!

ive taken out the ram, reseated it, tried a diff psu, no dice, took the cpu out and put it back in, taken the modem and nic out, taken the hd and the floppy out, and still nothing...

any ideas????

Try just putting the CPU in, leave everything else out. no ram, no vid, no nothing. if you get post beeps (even if they indicate errors) then you know those are good, then just start adding in components.. If your lucky and have a port 80 card, it will tell ya in a flash what's wrong

Sounds like something is hosing up at least one of your power supplies...either the 5v or + or -12V...can you check all of them for proper voltages? I suppose it's possible that the mobo itself has gone Tango Uniform.
Which HP model is it? Go here for <a href="http://www.hp.com/cposupport/software.html" target="_blank">HP's drivers & downloads</a>. Quite often, you can find the Service Manual or we might be able to find a good troubleshooting guide for you.
Go here for <a href="http://partsurfer.hp.com/cgi-bin/spi/main" target="_blank">HP PartSurfer</a>. You can find part numbers & HP prices. And you know what HP stands for...High Priced. <img border="0" title="" alt="[Eek!]" src="eek.gif" /> <img border="0" title="" alt="[Eek!]" src="eek.gif" />
Let us know how it goes...Good Luck!

Could be a faulty voltage regulator.
Also try removing leads to all other devices, including power to IDE and floppy devices.
Was anything added before this happened?

I didnt see you mention the video, is it integrated? if not, try a different card.

So which HP model is it?!? Are all of the DC voltages good or are they being loaded down?
