I went to bed last night and left my computer on, this morning I woke and and it was still on, but the monitor was blank (as usual). I went to my desk and clicked my mouse once to start the monitor back up again, but nothing happened. Now, this happens sometimes and normally I just restart my computer, but this time when I did I got 4 beeps a couple seconds after powering it on. Also, the monitor recieves power but no signal. The first beep is longer then the three after, but I have no idea what this means? Any help?

First of all - welcome to BC !


Make and model of computer ?  Since the beep codes are not standardised this information is important.
