Well after cleaning out my computer yesterday of dust, today it's been giving me problems in loading it up, it'll take a few minutes and doesn't like to just load up, it'll start then suddenly it'll turn off.
Once it's on it doesn't give me problems, but it's getting it on which is the problem.
I think it's the power supply but I wanted some more opinions before going out and spending money on another power supply and time installing it.
