I recently build a PC using the following specs (Intel Core 2 Duo E600, MSI Neo P965 mobo, 2gigs of DDR2 667 ram, a SATA 250 hd, Radeon X1800XT, two PCI device and a dvd burner, plus a 520 wat psu.) I installted WinXP fine, and was able to successfully start up Windows about 5 times, but then I added a PCI wireless network adapter and ever since then it will start up but then I'll get a blue screen of death error. Any advice would greatly be appreciated.
