cant start windows, screen just turns black
hi everyone, im new to this forum, i just found it on google when i was trying to find out what was wrong with my computer. When i start my computer it does everything its supposed to but after i type in my password for the network, the screen just turns black. In safe mode, it does the same thing, but it turns gray. i tried reinstalling windows and it wont let me because there is a invalid long filename extention or something when it runs scandisk and it says to run scan disk for windows, but when i do that it just keeps restarting and i let it run all night and it didnt finish.
now for my other computer. i think its an easy question, the video card doesnt work, the monitor button turns green for a second then turns orange again and the keyboard and mouse dont turn on. do you think i need a new motherboard?
