i thought if i changed the title, maybe it would attract more people to help... :]
I have a Windows XP Desktop PC and it was working just fine earlier today. perfectly, actually. no pop-ups got through and nothing froze and everything was great. So i got off and powered down and when i tried to turn it back on it stopped and did that thing with the flashing underscore [i'm not very computer literate] and said something along the lines of "Reboot or get new boot media..?" i don't remember. anyways. i need my computer back for school.. so people should definitely help me out please! haha. i'll get what it told me word for word later but i can't get on the computer right now.
PLEASE HELP ME!
