I just installed service pack 2 and when it told me to restart i restarted and the computer wont turn on. I press the power button and nothing happens on my screeen. My monitor power light shows up as if the computer is not on but my computer power led lighs up. The computer turns on but nothing comes up on my monitor. This happened right after I installed service pack 2. Does anyone have a idea of what if messed up on it. Its a celeron 1.4ghz 256mb ram compaq computer. The time before i installed service pack 2 the computer turned on but it just froz and restarted so i just reformated now i dont get any screens so i cant reformat nothing!
