computer problems, what kind of notebook do you suggest/have Options

alright, as the title says my computer is screwed up
-to start off, i have a dell inspiron 1150 (not the best in the world) and it keeps shutting down on me. i can rarely get it to turn on (it was just working fine a couple days ago) and in order to turn it on (most of the time) the cd/dvd drive has to be open, and even then after it does boot up, if i eversomuch as touch it it will automaticaly shut of on me, i have tried many things and i can't seem to figure it out.
-i was told the problem could be the motherboard and that would cost me more than the computer is worth.
-i know that i will probably need another computer, but i just wanted to know if there is anything i could do to maybe try to fix this problem.
-this did, like i said just happen all of a sudden, i dunno why, or if this is common.
-any feedback or suggestions would be greatly appreaciated, for i am not very computer savy.

im pretty sure that my power supply is good because when i hit the power button the power light goes on. the light usually blinks on and off and nothing happens, but occasionally the light will go on and the fan will also go on but nothing else will happen.
-that ever happen to anyone else before?
