Hi there! I have and Advent 5303 laptop, it runs on Windows 7 Ultimate and has Nero 360 installed. I know I dont have a virus because I've scanned multiple times. When I start my laptop up I hear one long beep. Iv searched everywhere but cant find out why it does this. I know there are lots of other types of warning beeps, like one long 3 short etc, but cant find out why mine does one long and nothing else... Could anybody help me with this as it is really annoying. Its near enough brand new, iv only had it about 6 months. Any help would be very much appreciated! Thanks in advance, Eamonn.
