[HELP] Blender 2.49 screen load really slow on Win 8.1 64 bit

Hi guys, please help me
I had never had this problem before when I use my old win 7 32 bit,
It came after I had clean install OS Win 8.1 64 bit,
My blender 2.49, the screen run / load really slow, for eg. the splash screen when you first open blender, it load line by line really slow, and all the screen when I click like: file, add, timeline, and other panel option it load really slow line by line.
The funny thing is it only effect my screen load, other like import and modelling no problem
I think this problem because of my driver adapter (Mobile intel 4 Series chipset family (mircosoft coorporation - WDDM 1.1), I already update it btw and still the same problem
Are there any solution to this problem, should I get another drive adapter or do anything?

BTW when I run above version of blender 2.49 like blender 2.5x & 2.6x, this problem didn’t happen, but I really need to use blender 2.49 because it has .nif script, which can’t be run on above version of 2.49

I hope someone can help me
Thanks
