Does the machine boot?
My PC (with Windows 7) has a problem when starting up, when I turn it on, I click start Windows normally (like how I used to do) then it get stuck and take me to a blue screen saying stuff about newly installed software and hardware, I searched online and it said to use the safe mode, I saw videos and other stuff, but when I try on my pc, I click safe mode with networking, it loads some stuff then take me to the blue screen again, I thought maybe I need to reinstall windows, I don't need to backup my files. If I need to, can u tell me how to delete the current one first?
