Compatible PSU with socket 478

Ok finished reading bear hunt to kid left it off, power on, psu fan and motherboard fan working. Hdd whirring, Cd drives purring!

Not booting up!

Camuk,
making any progress?

OK, if the motherboard has been replaced in this computer, the boot order may be wrong, (in BIOS) and it may not have anything to do with the PSU. This assumes that the 4 pin CPU plug is connected, and is making good contact.

Sorry to report though, the old Windows installation may not be optimal for your new hardware. (When changing something like a motherboard , XP and all the drivers should be/ may have to be reinstalled). Hopefully this may not be true if the new board is a true identical replacement.

So could this problem cause the computer to not boot up.

All drives are receiving power however does not want to work.

Replaced the motherboard with one that would work with Intel 4 hence a very old motherboard!

Progress, if nothing by the end of the week will film it flying out the car window on the motorway or should that be a free way at 70 miles an hour!!

You tube here I come!

Hi Camuk,
I didn't get in on the first thread you posted in may,where the result was changing out your motherboard. I wish one of the techs you had look at it would have told you that making a major hardware change(in this case the motherboard) requires a 'repair install' or a full clean install (preferred). thats why its not booting. any chance you can locate the missing XP install disc?


Oh yeah....what Captain said

Can get a copy luckly have the orginal serial code on the side of the machine.

Sounds like Captain may be right but how do I change it if it wont even boot up!

Hi camuk,
well you need to go into your bios and change the cd to the first boot priority. restart the machine and hold down delete key (i think it would be delete on yours) and get into advanced bios features. from there you can make the cd drive the first boot priority. then you put the xp cd in the drive, and restart the machine. it may say hit any key to boot from the cd drive. a couple of things.
1) you have to decide if you can do a full clean install (will lose all data on the previous install) pics, docs. etc. if you cant do that you can do a system repair of the original install.
2) you will need the product key for the XP disc to activate the installation.

Will try but if I cant even get to the BIOS or Dos I am in big trouble!

That's what i mean by not booting up!

you cant get into the bios?

Nope computer will not switch on, fan start, disc start and HDd start so all making noise but not starting i,e. no bios no on screen message, chooses when it wants to start up so I know something must be going as it has logged in and asked me reinstall windows which is the problem I had before switched off at the back of computer left for 10 minutes and since then will not switch on!

The only technical term I can give is FUBAR

are you hitting delete key to get into bios? and are you getting any beeps?

even better no internal speaker!

like i said i wasn't involved in the first thread about your motherboard, so i have no idea why they (the techs ) thought you needed a new one. and i don't think its your PSU at this point. so if you want to start from scratch, give me a holler.

The techs refer to the guy in store.

Going to take it to a mate and see if he can fiddle with it! So fed up

by the way this is the kid solution.

One every one in the house so none gets upset when someone else wants to go on.

So he can play tonka and I can cruise the internet!

Tech Speak......

1. "Won't boot.....! This means the computer won't load the OS (Windows).

However; Won't POST (Power On Self Test). Is more like what's happening to you.

This is when you can't even get as far as the BIOS screen.

S*** happens in this order, The computer tests itself (POST), then the BIOS "boots" (not exactly) the BIOS polls the hardware ( screen rolls by with the hardware and controllers listed), THEN, the computer "boots" into Windows. So we're missing a little in the description.

There is a thread around here about computers that won't POST, which is here; http://www.techspot.com/vb/topic113137.html

Eureka,

Its fixed.

Well guys my kid brother drove 4 hours last night and brought up 3 old computers fitted the internal speakers and finally we found out the error code 2 beeps then 6.

So he unistalled the motherboard, reinstalled the other one, swapped out the PSU no joy.

Put it all back put another motherboard, tried different memory and then at 4am this morning changed over the usb jumper. So simple!

Happy to report computer now back and working with second fan to combat overheating problem. All working, games, antivirus and all the other junk loading on, just trying to learn how to use windows 7!

By the way it was a ps2 to keyboard jumper.

The clue was apparently in the 2 beeps!

if you solve the problem
plz share it
