I am using Dell Inspiron15R(N5010) with Intel i3Processor, CentrinoWireless - N 1000 and Intel HD Graphics installed with Windows 7. I am facing the problem since yesterday that whenever I am trying to start my system, it is showing an error - RealtekPCIeFE Family controller Series v1.19(08/10/09) exe-8:E61: Media Test Failure Check Cable. I have 4 GB RAM (2 x 2GB) which I removed and tried to power on but system does not go beyond the error message. I also tried to re-install Windows 7 but getting the same error time and time again. Please suggest.
