Dell Latitude D820 WinXP SP2 2Gb RAM 2.00GHz Intel Proset 3945ABG Card A month or ago, I was trying to setup a bluetooth connection between a Trimble GPS unit and my laptop to transfer files. Something happened and I'm not sure what. Since then every time I flip on my wireless switch the system locks and crashes after about 3 minutes. The BSOD, when I get it, gives an STOP 0x000000F4 error (0x00000003, etc.). BUT my computer works flawlessly when I don't turn the wireless card on. I've reinstalled Intel's proset software, and reinstalled drivers. I've even removed the software and turned on the wireless switch (with no connection software present) and it still locks up and crashes. Any ideas?
