I was trying to open Google chrome in my Toshiba L455D-S5976 but it didn't shown anything aside from the URL and the bookmarks bar. The content of the app was pure black. Right after that a blue screen appeared saying "windows has encounter a problem, to prevent further damage the system will restart" or something like it. When it came back up it say “run Windows repair" so I hit enter and restored to back previous recovery point...but now is pure black. I can hear the fan going up and down but that's all it does. I took the battery out and hold the power button for 3mins but it didn't work. I also check the RAM stick and even change it from one slot to the other but still the same...I don't know what else to try, any help would be very much appreciated. Sorry if I'm not very helpful...I'm not that good with computers. Please help me.
