I'm trying hard to understand what u r trying to say...

I read, thrice; I got some few points here:
You reformatted your computer last night. (22 April)
You solved all problems except for the blue screen.
The HijackThis log is after u formatted your pc? If after, then there is nothing to check...
You do not need to to disable the dumprep program...

If this is correct, what I want you to do now is:
1. Find an updated driver for your graphics card.
2. Post your new minidump files here.

I suspect that you are installing bugged drivers, that is why u still face the BSOD after reformatting.

Heh, i already know the problem. You using old or non-genuine windows right? Driver updates required...
