Will changing the CMOS battery cause my Dell Inspiron N5010 to give me a beep code of 4 which is ram trouble I posted once on here this morning and no-one ever answered my question bout this I get a 4beep code but I've check my ram and stuff it's all good but my Dell still wont boot up to windows it just beeps the 4 code , fan runs HHD runs everything seems ok but keep getting that code I can't figure out what could be wrong unless I have to buy a new motherboard or something. If someone with the expert know how could advise me on this I would be Grateful Thanks in advance .
