If you can Shutdown, then press the power button or such, then it's something like:
A. Drivers. Many are just learning the Microsoft doesn't supply/install drivers for your hardware. Many are rudely awakened when asked "What video card do you have?" so drivers can be found (and for motherboard and more.)
B. BIOS. The BIOS must be uptodate and not set to any agressive settings. Many resist having a current BIOS, and will have to live with their decision since this is "on the list."
C. Other software. Review the XP Shutdown article a couple clicks off of the page at http://www.aumha.org/articles.htm
When I reboot, it goes through the cycle until the background screen comes on. Just before the icons come on the desktop, It makes an attempt to go to the A drive for no reason. No Icons end up coming on to the wallpaper background. The background wallpaper is displayed with the cursor. I can start in safe mode, the icons come on but can't seem to restore my computer. I choose a checkpoint date but it does not want to restore it. I can't get on the internet. I'm running XP on a router. Any help will be appreciated.
