I have a Toshiba Satellite C655 installed with Windows 7 Home Premium.
Earlier today, I tried to edit the Virtual Memory limit. It worked fine the first time, but upon restart a second time it would not boot. I am seeing the Toshiba logo screen that offers the F2 and F12 menus briefly, but it's mostly a black screen with a white blinking cursor.
I've tried the classic "Turn it on/off", reinstalling windows, etc. I cannot get the menu for Safe Mode to come up by pressing F8, either. Is there anything I can do?
