I have an inspiron 1525, it hasn't really worked for about a year. I have the charger and it charges and turns on, but after the dell logo loads, then the screen just goes black. I can tell that the computer is still "on" but i cant do anything. Ive gotten menus up and stuff by pressing f2 or f12, but i don't really know what to do beyond that. I would like to try to do this myself rather than paying for someone to look at it. Thanks
