Hi, Am having trouble with a Single Beep Sound at startup. Am using Intel P4 3.00 Ghz Processor, Intel 915 GAV Motherboard with 512 MB DDR1 Ram. The problem came when i installed a new 1 GB DDR1 Ram. Pc has detected the ram and working fine, but with a single beep when i switch on the pc.. and dere r 4 memory slots and am in a doubt dat in which slot should i use my 512 mb and new 1 GB DDR1 Ram.. Could u plz help me.. Thnks in Advance Aneesh
