[Wolves] Any clever Ideas???

[Octavio Augusto Sánchez Velázquez]

Hello, I don't know what happened to my computer, it was working fine, I
could use desktop effects, and I could watch movies with mplayer and
stuff like that, I tried to view one movie on my tv connecting it to my
pc (I have done it before with a proyector) It told me it needed to
reconfigure something (i didn't understand completely what) and I
clicked ok, gave my password, then restart my session and now I can't
use effects nor view movies, it says I have not enough resources, what
can I do? If you can tell me how is this kind of problem called, I can google it, any way, thank you.
