Hp pavilion 700 black screen help

[prod7]

my computer turns on but when it gets to the xp start up it just goes black. the screen was also small i fixed that but it still will not load and it then shuts off i think its the power supply because my kid was messing with it but what else could it be if not that?

will it boot up in safe mode?

it wont give me the option for safe mode , i tried f1, f9 , f10, i have f'd it to death lol. and no it will not come up i get as far as when it starts loading windows xp and then it just stops and goes black.
