-=PCTechTalk=- Re: computer won't boot

Did try another card. Neither has a power plug, just run off
the mobo. Maybe
it's time to start trying parts in another computer. Might
be worth changing
power supply first. I'm thinking mobo problems but I don't
want to, and I've
never seen one go so quickly without warning. Whats the boot
sequence/ I see
it checking the drives, what's next, counting RAM?

Jo Ann,
    I'm getting down to much smaller ideas, so bear with
me.
 
    My next thought is that some video cards require a
separate power cable
from the PS.  Can you check and see if yours has a
connector?  It would be
on the side edge of the card opposite the metal blade (with
the screw) where
you plug in the monitor.  If there is a connector and
there's already a PS
cable running to it, reseat it to ensure good contact.
 
    Oh, and please confirm that you did try a different card
in there.  And
that if that second card has the connector above, that it
also was plugged
in.
 
Peace,
GMan

Jo Ann,
    This only seems like it's affecting your video signal,
right?  If so, I 
don't see the PS as a main culprit.  Doesn't mean it's not,
but it's 
unlikely.  Unless the PS isn't rated high enough.  To be
frank, I'm 
concerned about the video card not having a screw when you
opened it up.  If 
you were only getting a partial connection with the port,
it's possible that 
it could have shorted out something (and you probably know
what that 
something would most likely be).  Still, replacing other
parts is easier 
than tearing the system down and rebuilding piece by piece.

    Turn on the system and power is supplied to the
mainboard and everything 
else that is directly connected to the PS.  Optical drives
initialize, hard 
drives spin up and fans begin to spin while the BIOS jumps
into action.  The 
BIOS reads the data in it's memory and starts testing the
items it's 
supposed to have (in  no particular order:  mouse, keyboard,
system timer, 
chipset, CPU, RAM, floppy drive and finally the  hard
drives).  At this 
point, it turns over responsibility to the hard drive
designated for storing 
the OS info in its Master Boot Record (MBR) and Windows
takes over from 
there.  Since it only gave you a single beep, we know that
the mainboard is 
unaware of anything wrong.  A single beep is the universal
BIOS signal that 
no errors have been found.  All other beep combinations must
be looked up 
for that particular BIOS, since they are all different.

    Reading that back to myself, it dawned on me that a
connected, but still 
loose, keyboard or mouse cable could cause bootup problems. 
Try reseating 
ALL of the stuff connected to the back of the tower.

Peace,
GMan
