[newbie] X Loading trouble

[Solver]

I wonder why this always happens to me, after several days of using Linux. When I type startx in the command prompt, the violet screen comes up, but the GNOME won't appear - or it takes it some 5 minutes to appear, in meantime the PC doesn't even think. Why this happens? The only solution I've found is reinstalling Linux, but there must be something else. At least, how do I reinstall only X? Solver
