I am trying to remove a Linksys WMP54G V4.1 PCI wireless adapter from my PC. I have uninstalled the drivers and software for it, but after I removed the card, the system would not boot. The BIOS is set to boot first from a CD and then the hard drive. However, it will not boot from a CD or the hard drive. It completes the POST up to the point where it is supposed to start Windows (XP SP3) but Windows does not start and the system locks up. I have tried setting the CMOS back to default values, but that did nothing. If I put the card back in the machine, it will boot normally, but not without the card. There are no error messages. I have an Alienware Area 51 7500 desktop, 4GB of memory, a 1.5TB RAID 5 with 3 drives and a 1TB disk for the C drive, and a 2.7GH quad processor.
