Blender freezes Help

Hi, Whenever I start Blender it freezes (see image), sometimes it ends up working after 30 or 40 seconds of freezingand other times it simply doesn’t work and there’s no way I can stop the program (can’t kill the process via cmd or ctrl-c in the console, or through task manager) and I have to rebbot my computer and it’s really annoying me.
I have uninstalled Blender and reinstalled it, I have tried the version without an installation (the zip file) and it doesn’t work.

Can anybody help me please.Thank you

PS: I have been using Blender for 2 years and I had never met this problem before.

My specs: Intel celeron 735 MHz/256 Mo RAM/Windows XP/NVidia GeForce4 MX 440

I had a problem with QuickTime Alternative 1.71.
I had to unistall it and then blender work again clearly.
So try to remeber what have you installed before your problem appears.

BTW probably bad forum section…

please ask this in Support -> Basics & Interface.
