I get black screen after booting windows 7 before login

Hi, all
I thought this is the correct place to ask this question. I upgraded my system with intel DG41 board and 8GB of ram, and it works fine...

only somtimes when I boot into windows, after the booting screen, just I see a blank black screen, no task manager and explorer too,
I tried different drivers for my nvidia 9500gt, and still same problem, and when i shutdown (holding the power button), and restart, then it works, it log in to windows normally

can anyone help, please

Re adding RAM
Ram comes in various brands, voltages, and timings.
You want to be sure you match those specification if you desire to keep the same type of memory you have.
It is said that the speed of memory you put in your PC is important because putting a slower speed stick of memory in your PC will cause all of your memory to run at that slower speed.
{I have never added RAM thus no experience here}

Links FYI.
