I flashed the bios to P0H and my problem has disappeared. I applied the same overclock settings in this bios and it boots everytime. Also, it boots faster, and XP loads noticeably quicker as well. Also shutting down in Xp is quicker as well. Before it seemed like windows locked up while shutting down as it took a long time. Now it shutsdown in about 8 to 10 secs. Clearly there is something wrong with the 130 bios. Also, does anyone happen to know what the Auto Xpress feature is, and what it does? I currently have it disabled.
