Resource Conflict, PCI Serial Bus Controller on Motherboard

By TelMan349 ·
My laptop will not boot up. I get an error saying: "Resource Conflict - PCI Serial Bus Controller on Motherboard". There are no devices attached to the laptop. And when I try to go into the Setup to try to boot from a CD it still does not work. Basically I am not reaching the Windows part of the setup.

Is the NB showing the POST Screen?

If it is you can try to enter the BIOS and reset everything to it's basic setting and try again.

The error message that you are getting is telling you that some devices directly connected to the M'Board are in conflict and are attempting to share the same resources. This generally happens when the BIOS has been incorrectly setup or the M'Board is failing.

NB's by their very nature lead a hard life and quite often it can be a short life depending on how they are treated. I've seen people allow them to go into Hibernation and pack them away in their carry bags and then wonder why the CPU gets cooked as they think that the unit is turned off when its actually still running. They also tend to get placed in positions where they are subject to bending the chassis and this causes problems with the M'Boards as well and eventually they will fail totally.

But if someone has altered the BIOS recently that will most likely be the problem as everything is built into a NB and they all need their own resources to allow the NB to run. Remember that just because you have nothing connected there is still at the very least the LAN connection, Dial Up Modem, PS2 Port, Monitor present at the very least and these need to have the correct resources allocated to them to allow the system to work correctly.
