what kind of software do you mean? I'm guessing its not an old version of windows, but if it is you could buy a new copy.
If you're having problems with a graphics card (and you have a dedicated card like a Nvidia or AMD card) you should try updating your graphics drivers if you've never done so. Just google the card you have and something like "updated drivers"
Not sure if there are new drivers for integrated cards but its possible. If you do have integrated graphics you should check just in case.
Hope you get your computer issues sorted out soon.
