"STOP 0x0000007E" error message after you upgrade to Windows XPhttp://support.microsoft.com/?kbid=330182
(Personally I would not update the bios until it becomes the last possibility because an error during a bios flash can toast your motherboard - make sure bios settings are set to safe default configuration and the boot order to boot from CD first - you can change it back after completing your Windows installation)
If you have just done a fresh install of Windows (or are trying to do one), do it without any peripherals connected to the computer and minimal installed devices, IE, 1 stick of ram but a minimum of 128mb, no sound card, no video card either unless you do not have an on-board video adapter on your motherboard.
Use a basic wired mouse connected to a PS2 port (not wireless or usb)
Only the keyboard (wired and PS2 not usb), the mouse and the monitor should be connected.
Do not connect your nic card to a cable modem or router
You can install all other devices after you get Windows set up, but do them one by one. reboot and make sure each installation was successful and caused no problems.
