Brand new XP user & system with errors

I have a brand new XP (home version)system and in the first 2-3 days of use I have encountered some strange errors that I am clueless to. I hope someone can offer some assistance. This is not a networked computer. 40GB, 256K, 2.4GHz

1) WindowsMedia Player V8.0 error code C00D2EE7. No other information.

2) When logging onto Windows:
*Unhandled Exception C0000005 at address
100016b8.
