@essexboy, like I wrote earlier, I was once able to boot it up with F8 or F10 to get to boot menu, I could see the Safe Mode and other options listed but I could not move the cursor using up and down arrow keys to get to SafeMode option. The mouse i.e the up/down arrow keys didnt’ work which was similar to some other virus which takes over mouse and this is why I was inclined to think this was perhaps not the case of broken screen but virus, I am so not sure.
