Miguel, The system just out of the blue reboots. &nbsp;No BSOD at all. &nbsp;I replaced the motherboard and Video card and tested the RAM and is still is doing this. &nbsp;This system was just built clean with all new items. &nbsp;New MB/RAM/Case/Power Supply/Hard drive, &nbsp;everything brand new. &nbsp;The default gateway is set to 192.168.1.1 and my dns server is set to my ISP DNS Server. &nbsp;<br />
<br />
Thanks for helping.<br />

Windows XP reboots with Event ID 4321

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
