I have Windows xp and have had no problems til after I installed my linksys pci network adapter.. worked fine for a while, lent the computer to my brother and now it wouldnt even turn on..I took the pci adapter off of the computer got windows to start up. I however now cant uninstall the driver for the pci so that I could reinstall it. I got the internet to work with an ethernet cable and then put the pci adapter back in and had it working for 2 days and then the computer shut down and wouldnt start back up til i took it back off. now i cant connect even through the wired connection. I had to use system recovery and cant figure out how to make anything work now.. where do i start?
