Booting problem

[jsam74]

Hi,

New to forum and have only limited knowledge so no expert.

I have a pc from my sister which required a new mobo. I have installed a new mobo , new cpu (amd) and memory (1gb). These were recomended by the shop.

I have installed all the hardware and went to power up. I have power, fan running, power to HD (can feel it running) but "no signal" on screen.

Have I forgot to do something. Not sure what i was expecting on the screen but it says no signal. I have checked all cables to the mobo and the screen.

Regards

John

Do the out-of-case-troubleshooter as described (motherboard out of the case with only the parts listed assembled together) and then let us know what happens.

What kind of computer is this? Home built or name brand?

Do you know the entire system specs? If you do, please list all the parts by brand and model including the power supply.

If this is a name brand computer did you check to see if the motherboard power connection from the power supply has a standard ATX pin layout or a proprietary one?

Hi Cricket,

The PC is a Packard Bell Imedia 4706
It was bought complete from shop. It s my sisters unit, wouldn't start so she took it to shop and they aid new mobo and it would cost here £180. Thought I would have a go.

Packard Bell 4706
AMD Sempron (am2 socket)
NVidia NF6100-400 MOBO
Kingston Memory 1gb
Western digital HDD (original)
Eye T IDE controller card
FGP Grp Power
Input 115/230v , 10/5A , 60/50Hz
Max Output 200w

I have just noticed that when I fire it up I cannot hear the CPU running (normally a crackling type noise).

In terms of the test you asked, do you want me to take the MOBO out of the case and take off the memory card, expansion card, CPU?

Apologies if I am asking silly questions Cricket, this is my first attempt.

Regards

John

Packard Bell? From what I remember they are very proprietary and you can't just use any off-the-shelf parts in them. If the power supply uses a proprietary wiring scheme you may have killed that replacement motherboard.

I am not sure around the power supply.
I did take the model and the old board in to the shop.
If this was the case what would you advise as the PC is around 7 yrs old I believe and they do not manufacture the same mobo's any more.
Is there something I can do to change power or is there a certain mobo I should be looking for.

Regards

This is going to sound brutal, but see if you can return those parts. A 7 year old Packard Bell is not worth repairing or upgrading, it needs to be completely *replaced*.

Also that PSu woulnt've wrked at all with the motherboard, it is 20 pin and probably lacks the 4 pin cpu power. Take glc's advice and try to return the parts and use the money to buy a new pc.
