Shader Pack Bug, Crashes When I Select a Pack

I have successfully installed forge, optifine, and the item physics mod. After installing optifine, I downloaded a few minecraft shaders. My game runs smoothly up until the point when I try to select a shader. When I try to select a shader, my game crashes.

Above is the entire copy/pasted warnings in my minecraft game output. Nothing new came up after the crash, so I'm not sure if that helps at all.

I know you have handled similar problems, and I even saw numerous videos involving the solution to my problem, but they all required a program called NVIDIA, which I don't have. I'm not sure what to do, could you please help?

My computer is an hp Pavilion HPE h8-1010 PC, Windows 7, and intel core i5-2390T. It also has a Radeon HD 6450 graphics card.

I'd prefer not to have to purchase anything, if it is possible not to, but if that is what I must do, then I might do it.

Sincerely,
