If I stay with this driver, will these be affected(this gpu is old(for vista), and has no "official" drivers for 7)?
Also, will I not be able to use future versions of blender?

Will there be any issue such as slower render times or malfunctioning 3d viewport? will it affect rendering even though I use cpu rendering?

Ah. Ok.

And the following is the system-info.txt.

Using the arrows? No. However I can use right click for that, so no big deal.

Since I can't buy another computer or change the GPU, is there any way I can reduce lag while using opengl32.dll?

So does this mean that it is a driver issue? To quote Bastien Montagne (mont29):
"Try to place this dll next to your blender.exe (software OGL, will be slow, but will show whether this is a driver issue or not)."

I'm putting this at the top and in bold to emphasize:
With the opengl32.dll file, resizing DOES work.

1. They are.
2. I downloaded blender 2 days ago, and I don't think a new download is an update. If it is a new version, please tell me and I will download the new version.
3. This did not fix anything.
4. This didn't do anything.
5. I don't have GPU driver settings (this computer originally came with a Vista and was upgraded to 7)
6. When I open blender, it says:

"C:\Users\chef\Downloads\유빈\blender-2.75a-windows32\blender-2.75a-wiondows32\OPENGL32.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support."
Downloading the dll again and opening blender gives same results.
