I need some help with a PC I've been given.  Here's a little background first...

The computer was given to my mother by a friend of the family.  They told her that it may have had some viruses, etc, and the problem they have (whatever it may be exactly) would cost a lot to fix.  So they went along and bought a new one, hence why they passed it on to my mother.

Anyway, they tested it and stuff to see if it went.  Things were OK at first, until something happened that ended up frying the power supply.  I offered the ATX from one of my old PC's...but due to the size of our friends' computer (an HP Pavilion, about 3/4 of the size of your average tower), my ATX is too big.  But I had a cunning plan...

I took my old tower with the ATX in it (my mother decided to just give the other PC to me, by the way) and then I opened it up in a way so that I could link the 2 towers together by its cables.  In other words, my old PC tower is powering up the smaller one.  (not a bad theory, yes?)

But this is where the main problem I'm facing comes into it...........

For some reason, the monitor always wants to remain in standby mode when it's booting up.  I know it's not the monitor, because I tried it on 2 other monitors (including the one I'm looking at now).

What do I do so I can see what's happening to the other PC?  I'm stumped.  Truth is, I don't wanna have to put the drive into this computer to format/scan it, in case anything harmful gets into my important files.

Anyone?  (sorry for rambling)

wowowowo ... hang on a sec ... a little complicated let me have a go at getting a picture of what you've done ...


HP Pav                            ATX
Motherboard ----------------Power
Video card-------                   |(? this one)
everything else |                   |
                      |                   |
                      |                   |
                Monitor------------------> Mains (? this scenario)

So apart from the power supply you havent touched any motherboard related stuff and the monitor worked before and now using all the same cable it's not working at all (or just at boot as you may be trying to imply)? And you're sure it's not the monitor because you've tried other working monitors.

Does the computer progress to boot (can you hear hard disk purring noises?

Pull out the connection at the video card and reconnect.

Or are you trying to suggest that you're plugging the monitor into the power box and it has problems? Get an electrician!

Here's a rough guide of the setup as it is now:

PC #1 - My old computer, containing...

ATX power supply - with its cables plugged into the motherboard of PC #2
3.5" Floppy Disk drive (which I can't remove, due to a stripped screw)

Everything else, except the power switch and its cables have been removed.


PC #2 - The one given to me, containing...

Motherboard, etc
CD-R (possibly DVD Player) drive
3.5" Floppy
HDD (unknown size, so far)
RAM (unknown amount...)
Sound Card

All necessary hardware, such as mouse and keyboards, have been plugged into this one, plus PC #1's ATX.
Monitor is plugged into this PC, yet it stays on standby.  Tried the monitor it came with, then the one from PC #1, and then the one I use for PC #3 (the one I'm using now).

Are you sure your ATX power supply is suitable to use in the other computer? i.e same voltage etc. if its not as powerful its obviously not going to work it.

the best way to find the problem is to strip the whole computer so theres just a motherboard in the case, then replace the other pieces of hardware 1 by 1 until it works, if this doesnt work then most likely its the graphics card

hey there it's not that no one can help - your problem is way too non specific, it's like asking "why doesnt my car start ... anybody?"

the only 2 categories i can think of is either there is a video card/not plugged in properly/cable/pins problem or something else!
