any help would be much appreciated,
thanks alot,
bright.
(Note: I can install windows 8 again , i dont care what system I have, i just need something that works properly)

Not real sure what you're saying here. You mean your windows installation is 250gb's? Did you follow these guidelines in your install? Clean Install Windows 7 There are other factors involved in an upgrade from 8 to 7 also.

My harddisk size is 250 GB, and i followed everything in that tutorial.
but like, the free space of harddisk storage is decreasing by itself, thats what i need help with, not to let it decrease without doing anything
D:
someone help meeeee

Is this a new PC with Windows 8 Pre-installed?

no no
i installed windows 8 on it, but then i wanted to format it and i installed windows 7. and this happened
the PC originally came with Windows vista, but that was years ago, and it was all fine till i formatted it yesterday and that happened
also, i formatted it many times before and nothing went wrong, i have had windows 7 before, i have no idea why this is happening now

Lets see whats eating up all your space. Download and run this, and then post the log/or a screenshot.

That's what I got.

There is no image. Can you upload it here ?

I would Check your Users folders.

you have 50GB of .avi Video clips.

Dang. Look, the Users folder is taking up all my space,
but really, its emp-ty.
EMPTY.
Doesn't make sense
