hey guys, im using nero to burn CDs with my CDRW. i have a dimension 4600 and its been acting up lately. the last 8 CDs were bad burns and i tried 2 different mediums. All which worked before. i even tried different software record now, and easy CD creator. It starts the burn but fails in the end. the simulation works fine but when i actually have to burn the CD it fails. i turned off all other applications and have over 700mb of ram. whats the problem guys? or have u guys had any problems like this. my dell is only 3months old, what should i do?
