I have a PC that runs Windows XP that I have been using for a few years. It
is custom built using an MSI 865GM3-LS motherboard and an Intel Pentium CPU.

On booting up it now gets stuck at the first bootup screen which
displays an MSI logo on the top left corner, and Intel Pentium Logo on the
lower right corner and some text in the middle that reads "8Xtreme Series",
"Performance, Durability, Stability",

I have reset the CMOS by setting the jumper to reset it, but still have
the same problem.

Help!! What is wrong? Is the motherboard bad, is it the battery, what is
it?

Thanks!!
