I have a HP Pavilion a1338.uk running WinXP SP3 IE8 and have problems with the dvd writer which was already installed when the pc was bought. No discs came with the pc. When a bought music cd is played, there is noise in the form of clicking. It is random clicking and not very loud, but audible. The cd plays ok in a different player. When recording music files to a cd, the clicking is present. But when the cd that has just been made is played on a different player, it's ok. No tapping. The burner is a Sonic DigitalMedia Plus v7 all-in-one type. By that I mean it coppies a disc, then ejects it and asks for a blank cd to copy to. The time it takes to do a copy has slowed right down, too. Ideas anyone. Thanks in advance.
