PCI Controller error

  Paspatoo 14:08 PM 16 Aug 11

Hi all,

Has anyone else experienced the following:

Boot your laptop and, shortly afterwards, before windows starts up, you see in the top left of the screen: "PCI controller error".

It gives the option (for a very short time), at the bottom of the screen, to press "f1" etc. but if I do nothing it continues to boot up as normal and windows starts.

This does not happen all the time as mostly the laptop starts without this message appearing.

My question is:

Should I be worried about this intermittent message as the computer seems okay?

Or should I try to 'fix' it?

I have scoured the net but cannot find anything which relates to this in this circumstance.

Anyone got any ideas as to what may be the problem?

Any suggestions/advice welcome

Next time press F1 which should take you to the bios , then have a look around and find "enable express card", "Disable USB legacy Support.Press F10 then enter to reboot your laptop.

But I must add that if your PC normally boots up without a problem then you have to wonder if it is worth the bother. Try it and see you can always reverse it.

Thanks for the advice gengiscant.

I agree with you as to whether it is worth the bother as the laptop appears okay but you know how it is, these things niggle away at you everytime you see it and it gets you wondering if things are about to go haywire if you don't 'act on the message'.

I sometimes feel computers are sentient beings as they apper to chide at us, goading you to 'uprade', 're-install' or 'fix' things that you are perfectly happy with and then refuse to work because your 'fix' is 'incompatible' with something else which then needs 'fixing'.

I think I have finally solved this little enigma.....

Gengiscant's suggestion, about disabling USB legacy support, got me thinking about what I had plugged into the USB port... a wireless mouse.

I removed this from the port and, it seems, this has eliminated this message from appearing.

I now plug the wireless dongle in AFTER booting.

Just thought I would update this so as to assist anyone else who may be faced with this, seemingly, inexplicable message.
