No post on IBM Netvista PC

[alan.surry]

I've got an IBM Netvista PC that would not boot sometimes, but would boot OK on other occaissions.  It has now ceased to start at all, with no P.O.S.T. screen or BIOS beeps.

The power supply has tested OK,  I've removed the PCI cards & graphics card & note that there are no BIOS beeps indicating a lack of graphics card & the same applies if I try to boot it without RAM.  The odd thing is that is powers up, stops for a few seconds, then powers up again, but never gets any further.   The CPU fan is working fine, but without a spare CPU to test it with, I don't know if the  CPU is OK.  

If anyone has any ideas, I'd be grateful.


Best regards, Al.

How many sticks of Ram installed?
Are they seated properly
Can you remove one and try starting it, if that doesn't work, replace one with the other
Unless of course, you need both to work properly

Have you ensured all internal cards are seated properly
They may be a short on the board, just a possibility

Try disconnecting all periphials again, including keyboard/mouse
Will it boot

Just tossing in some suggestions

Will it boot with the Windows XP cd?

Thanks for the reply.  There's no cards & only one stick of RAM, but I've now made some progress.   I've replaced the AGP graphics card with a PCI card and it boots as far as the P.O.S.T. screen before giving me a warning "0135 fan error", which the IBM /Lenovo website list as CPU fan or Motherboard failure.  I  can choose to ignore this error and it boots OK, but I can't disable the fan error message in the BIOS. As the fan is spinning away like buggery, It looks like the board is on it's way, which could well explain the AGP port going down.  Looks like it's destined for the spares bin.

Regards, Al.

What is the exact make and model of your computer
In some cases a bios update has fixed this issue
