hello sevenforums 
This is my first thread in here .. I have a problem with my VGA when running under Windows 7, I've been trying to fix it myself for three days, was quite tired now, first, please see the system specs that I use, then I wanted to ask, whether the VGA that I use is compatible with my motherboard? if yes, why it makes my PC can't boot? I'm sure that the VGA is working 100%
a little story from my
when VGA is installed, it can be detected by Windows 7, then it automically installing driver, when it asking for restart, I choose "YES" (I forgot the dialog) seems like that, then,.. it makes my PC just can boot until starting windows, it can't full start-up, it hangs until (don't know for sure) my longest waiting is 1 hours
then I turn it off from power button and start it back from safe mode, Uninstalling display driver it installed two display adapter :sarc:
uninstalled both of them,.. then restart, windows found new driver again, until it finished install, I ignore it, I have my own driver downloaded from ATI Catalist Legacy Display Driver which it latest driver for my X550, I installed the driver throught device manager, then restart, it still same result with previuos, can't boot :huh:
then I go to safe mode again but not uninstalled, I just disable
It can boot, but no aero and no VGA detected because VGA is not installed clear, I trying to install catalyst but it can't detect my X550,.. I have downloaded previous driver at amd sites, and trying to install it but still same, now I'm tired 
I'm trying with previous driver because this warning from AMD

I hope with asking here will gives me solution to fix my problem
, I will gives every information in my system log if it needed, but somebody must teach me first how to generate log (error log or critical log or other log).. I'm sorry for my bad english,...
best regards from Indonesia
