So I was rendering a video on my computer and my computer suddenly shuts down. At this point the computer has a blank cd in it and two usb's. I reboot my computer , the hplogo pops up, then for whatever reason I get a message from my monitor saying auto adjustment in process. Once this goes by I get a black screen with a flashing underscore, which seems to last forever, hitting ctraltdelete restarts the hole process. I went into bios and changed my boot settings so hdd comes before cdrom,however nothing changes. by the way I have removed all those usbs and cds from my computer. I have a ot of important work on that computer and could any help given. But please make it understandable my knowledge of computers is not that deep
