Only fans run then PC's shut down.

[mjfletch]

Hi,

I recently changed the hard rive on my father's Lenovo 3000 J105 8259. Unfortunately, when I turn it on, the CPU and cooling fan engage but nothing else happens, the pc then shuts down in about 2 seconds. I have checked all connections and cannot see anything loose. I have also tried this with the old drive in but the same happens.

The spec of the PC is a follows:

Lenovo 3000 J105 8259

Sempron 3100+ 1.8ghz CPU

2gb RAM (was 512)

500gb HDD (was 80gb)

Thanks,

Have you checked that the PSU is working properly.

Yes I have checked the PSU setup on Lenovo's page and it is configured correctly. So It should be working properly. For example the light on the back of the machine stays on showing me that it constantly has power.

What happens when you turn the pc on without any hard drive connected, do you see the POST screen?

Hi,

 

I have now tried disabling the hard drive but im afraid the same thing is happening. I also checked the CPU. After putting it back the PC now does what it did before but doesn't power down just sits there with the fans whirring away.

Hi,

can I ask why you took out the old hard drive and replaced it?

If it was because you thought there was a fault in it as it wasn't working as it isn't now, I actually suspect the power supply could be the real fault.

There are various sections within a PSU, giving different voltages out of the supply, it could be any one of them not working but still giving the power to the fans.

 

Please also bear in mind, that when a power supply fails, especially in the lower voltage outputs, it can do damage to the mother board as well, resulting in the need to change both the power supply and the motherboard.

 

However if it is at all possible to obtain another power supply and try it, do so and see how you get on.

Please let us know one way or the other.

Hi,

I can confirm that I tried the drive in an external IDE device that allowed me to attach it as removable storage to my laptop. It sounds like the arm in the HDD was not engaging properly. Anyhow, I took another look at the motherboard and found that the CPU mount was slightly broken, so I swapped the motherboard and CPU out. Now I have a motherboard that boots into the bios (thus taking the power supply fault out of the equation). Unfortunately, although it recognises my hard drive it will no show the capacity within the BIO and now when I try to load an OS the machine will not recognise the drive as available. This means Im going to have to open a fresh request under the relevant category.

Thanks for your help

Hi again, OK we can rule out the PSU I hope if you can get as far as the BIOS, However I am puzzled about "I can confirm that I tried the drive in an external IDE device that allowed me to attach it as removable storage to my laptop. It sounds like the arm in the HDD was not engaging properly"

Do you mean there were clicking or knocking noises coming from the hard drive when you had it connected to the laptop? Could you access or see any of the files, do you have access to any partitions and what they contain, or even whether it was set for FAT or NTFS file types while it was connected?

I am suspicious that the hard drive is duff, which would account for all your problems.

Is it brand new or a second hand unit?

If new I would take it back and ask for it to be checked, or replacement of it.

Nev.

i agree i reckon yur hard drive maybe faulty.

especailly as the bios is not showing the capacity properly, and XP setup doesnt even find it..

if you can put it back in the caddy, and run a chkdsk on it....this will tell you off any issue.....

also the drive manufacturer will have diag tools, maybe worth running them against it too.
