Within few months of normal use of Windows XP running Toshiba NB200-10z laptop it has started showing problem. The drivers of my laptop went missing thus making it impossible for me to get on to the internet. When I checked the Device Manager, there is a question mark inside a yellow triangle near the “Ethernet Controller” and the “Network Controller”. What must be the problem with my laptop? Does anyone have any idea regarding this matter then please help me. Thank you in advance.
