Cant run Java on my computer

I'm running a XP pro (eng) with sp2 fully patched.
I've tried with several several versions of JRE but no matter which one I try, I can never get Java to work on my PC. Even Java control panel window apears grey to me.
[edit] Basically what happens is that I install a whichever version of JRE (lately i've tried 1.5.4, 1.5.6, 1.5.8) and after instalation I just basically try to open Java Control Panel on my windows control panel, and the window is just a slate of light grey. No tabs no nothing... just grey. [edit]
Any ideas?
