Report "I just bought this system: SYX OSG-2 Intel E5700 3.0GHz, Genuine Windows 7 Home Premium 64 Bit, 4GB DDR3 Memory, Nvidia 1GB GT430, 500GB Hard Drive, Lightscribe (SYX-1060), from TigerDirect. It powers up fine, the CPU fan is running, but the monitor is telling me to check the signal cable, and it's securely plugged in and all. I have no idea what else to do"
