hello im new to this forum and i have a big problem. one day while i was on my computer i got up and went to go get something to eat. when i came back the screen was black and the blue light was flashing. i moved the mouse and it didn't come back on so i turned it off and turned it back on. the problem went on for a few days until one day i left it on and turned it that thing i told you earlier. so i turn it off and turn it on again, but this time it turned on but it didn't show up on the screen. i thought it was the monitor but it wasn't. the wierd thing was that the computer was on but it sound like the fans were working overtime. it still does not work and it has been a week. my computer is a HP pavillion with NVIDIA graphics and AMD 64 AnthlonX2. i don't know what some of that stuff means but thats all i can tell you. i wll appreciate the help.
