Welcome Newcomer!
First, there's no XP SP4 and I doubt there ever will be more than XP SP3 -

I am totally confused what is going on ""asus p5kpl-am epu"(the blue thing)" - if you mean the BIOS Splash screen then you'll need to disable it in the BIOS:
1. Restart press the "Delete" key
2. Arrow to the {Boot} tab in BIOS
3. Change Full Screen Logo -> {Disabled}
4. Press "ESC" key and choose Save & Exit Yes.
Good Luck!
