zero.

can you provide more detail on the nature of the 'trouble' you have
been experiencing?

Well, the computer will boot up fine I'd install my Windows XP on it.
Then I turn it off. Couple of hours later, I come back to turn it on
and there would be no BIOS screen. The computer seems to reset it self.
Or if it boots the hard drive, it would show different error messages,
such as corrupted installation. Last night it hung during Windows
install. Seem to be a variety of problems.

Chieh
