Hi All

This is an ancient machine which originally ran windows xp but I put Windows 7 x64 OEM in it and have kinda had all sort problems with it and I am fairly sure the motherboard has died but see what you think.

OK here is what happened .. I had moved it and plugged it into my TV and used for an hour or so no problems ,,shut it down .. moved it back to its usual place, re-connected everything, pressed the power button and NOTHING!!! no power.

ok here is what I have done:

Re-Checked ALL Connections
Checked it with another PSU ..still nothing
used the unplugged all power sources and pressed power button for 15 secs trick thing...still nothing
tried removing ram 1 stick at a time and then both ..still nothing
tried changing the cmos battery ..still nothing

my main reason for posting is to get clarification that is sounds like a motherboard failure and also if I put another motherboard in it how will it affect me will I need to purchase another key or will I not need to do that I am clueless with these matters whats right whats not so and so on.

Also I have a similar motherboard just slightly later version, would all the parts work with it RAM,CPU etc etc or in theory should they work.

Old Motherboard: Albatron P4M800-775 v1.0

Replacement Motherboard: Esys P4M800/775 v3.1

if you need more info on all the parts I will try get them as soon as I can, I do not really what to spend any or very little on this as I am not sure it is worth it but if I can get it up in running again using what I got then it is worth considering


Regards :)

I agree that the "no power" could be a dead motherboard but it may also be a problem with the power switch or the circuit between switch and PSU.

In my opinion there is no point in spending any money on this (you could buy a refurbished Windows 7 machine as one alternative). Whether you spend any time using parts you already have is up to you.

I completely agree with this suggestion. Spending time and money on that "ancient machine" isn't worth it.
I just purchased a refurbished Dell PC for $230.00 which comes with Windows 7 64-bit and has much newer and much faster hardware.

Hi Guys

Thanks for your advice I totally agree that spending money on this machine is madness and looking at a refurbished machine is something to consider in long term .. but with that being said if it is lost then I see no reason to try and use that other motherboard to see if I can get some use out of it .. unless I would have to shell out for other parts then I give it up.

one thing about my current windows 7 install would I have to shell out for another key or do you think I should be OK

Regards :)

If you can convince Microsoft that you have replaced (not upgraded) a defective motherboard and have a legit Windows Product Key (you apparently don't, since on a computer with XP pre-installed you should have a retail Windows 7) then you'll be OK. If you get the computer running you can always fall back on a Linux distribution to make good use of the machine.

Hi

I forgot how to connect up the power switch and stuff to the motherboard if anyone can help

picture of pins on motherboard :

motherboard pin 1.jpg

connecters are:

Power SW
Reset SW
HDD LED
Power LED

All are black with 2 pin slots (probably all are just giving info)

Also got this thing from some page but not sure how right it is

Pin configuration pic.jpg

hope that helps but I am seriously thinking of just get a refurbished Windows 7 machine but if this powers up then I will know it was the motherboard.

Regards :)

Moved thread to Hardware (from Windows 7), as you definitely have asked a hardware question now. :)
