Oh god, I feel so damn idiotic today.
I'm working on a PC, a Window's XP one, very old but is a really good machine. Needed more RAM installing because the machine wouldn't run these new game's very well.
My granddad came up and helped me, and me and him broke it together, damn it.
It won't boot up, or anything, the screen will go on, and then flicker to idle.
Well, at least my computer isn't mega buggered, my granddad has gone down to fetch a XP boot disk, so I just hope it work's.
Also, this laptop I'm writing on can run these game's fine, but has a stuff hard drive space, so I can't really install any steam games on this machine.
