Hello,
i've cx620 3d msi notebook with intel processor core i3, windows 7 32bit, 4gb ddr3 ram and graphic ati mobility radion hd 5470 1gb .
oneday while i was working on my notebook suddenly screen turned to black and notebook was still running when i restarted notebook same problem was there .
finally i had to install windows 32bit again loosing all my data was saved on it without drive of graphic card because when i try to install it can't be installed .
now my notebook is working only with builtin graphic card in low power although graphic card is mre than 1gb but it doesn't work with games that need more than 512 m graphic with low acceleration power.
