My notebook is HP DV4 3115-TX,and I use Win7 23bit now.When I want to use the tools"Ready For 4GB"to get the full 4GB memories,my computer will restart automatically.If I turn to the safe mode or uninstall the Intel graphic driver at the standard mode,the problem will be resloved immediately.So I suggest you to fix this bug.Maybe you would suggest me to use the 64bit system,but in China,there are too many people around me complain about this bug，and now the 32bit system is the most widely used in china.I hope Intel would slove this problem,and it will made the customers more convenient.
