I just installed LoL on this computer, i have it on another computer and it gave me no problem, this tho is a bit old, and as i try to run LoL it says that "Video card does not support pixel shader 2.0". anyone knows if the problem can be solved? thx

I know the DxDiag info might be of help, still i don't know how to attach a file here :P i'll paste it below

Your DxDiag copy cuts off before the video card information. Looking at the stats posted, it looks like your computer is a bit old, if that's the cases most likely your hardware is not new enough to meet the minimum requirements.

Yeah, your GPU is causing this issue, you can shop around and see if you can pick up an old VGA card that supports Shader 2.0 (it allows pixel transparency or somthing along those lines thus games with transparent pixels in them can't / won't run) because I am assuming that on such an old system you don't have any PCI Express slots.

If there arnt any VGA cards with shader 2.0 support your only solution will be to replace the Motherboard to a more modern one, this would result in you needing to upgrade pretty much everything else ( bar the HDDs), so if I were you, I would either throw in the towel or get a new Case and build a system from scratch.
