Problem with PCI devices

My A85-S107 keeps having a problem with the pci devices after a reboot. I've used the system disk to restore to original & it'll work for awhile, then when I turn it on again, it does a search for the PCI device drivers. Checking the device manager, there is yellow marks on 3 pci devices & secondary IDE channel. I uninstall the problem devices & reboot & it then goes through it's mode of searching for drivers with no success? I've tried to reinstall the drivers from the disk with no luck! After several attemps 4-5-6 times of rebooting, everything is back to normal & works fine? I've flashed the latest bios from toshiba's site & that didn't help either. Any idea's out there?

 

I've got 2 0f these machines & both of them have the same problem. However, I noticed that if I disable the onboard Lan in bios, the problem goes away. Not a problem if you don't use a lan connection. It seems that Toshiba had a problem with the models A75, A80, A85's, So far I haven't been able to find a permanent fix.

 

The A85 has a problem with the southbridge where it will cause either the Wifi card (which runs on the PCI bus) or the network card (which also runs on the PCI bus) to not work properly. The southbrige is what has failed, not either of the network cards.

The problem can be intermittent, and if you hold down on the southbridge you can temporarily fix it, but the only permanent fix (barring having a 40 thousand dollar maching for repairing motherboards) is to replace the motherboard.

As Bourbonpete said, if you dont use these devices, its not a problem.

Bourbonpete, the A75 does not have this issue. It has issues of its own, but the network controllers and southbridge are not one of them.

 

After 2 days of Google and trying EVERYTHING i could think of, I came across this post and the 2 perfect responses that told me exactly what the problem was and how to deal with it.

I did turn off the LAN in BIOS as u suggested, and bingo.....no more conflict on those 3 pci devices! I am not sure what the other two devices are....since so far all that I think that I am having a problem with is my wireless card does not work. I do use my laptop on LAN, so now I have to decide if I want to try to attempt a "fix" to the Southbridge. Any suggestions on how I might put pressure on it to make it stay down permenantly? Do you think some type of adhesive? Is it posible to wedge something over it between the top side of the chip and the case?

OH....Would I still have the same conflict if I used a USB wireless card. I assume that the LAN would have to be put back on in the BIOS, and I assume that I would get the conflict again..... but not sure.

Thanks again yall!!!
