Hope someone can figure this out. I have the same problem as the above (ie, you can get only so far in the installation of XP and the computer switches off). Took the darn thing to CompUSA and they took it down to just the graphics card and motherboard but couldn't do any better. They called Microsoft and were told it was a hardware problem, then called Soyo and they blamed the operating system. I've emailed Soyo about a week ago but gotten no reply. I've since tried loading Windows 2000 but get the same results. If anyone knows anything I would appreciate any insight.
