Just ordered and built a computer for the first time in my life. Motherboard ASUS M4A88TD-M USB3 AMD 880G Motherboard CPU AMD Phenom II X4 955 Black Edition Quad Core Processor RAM Corsair 4GB DDR3 RAM Video Card EVGA GeForce GTX 550 Ti Hard Drive Seagate Barracuda 1TB Case Thermaltake V3 Black Edition Mid Tower Case Power Supply Cooler Master GX Series 650W Monitor Asus VH197D 18.5" Widescreen HD LED Monitor Assembled everything to the best of my ability. Everything screwed into (hopefully) the right places. Power supply is connected twice to the motherboard, once to the graphics card, and once to the hard drive. Hard drive is connected to the motherboard. All the wires from the case have been plugged into the motherboard. Connected the computer to my monitor and turned the computer on. My graphics card, CPU, case, and power supply fans all started running. LED lights all turn on. No beeps were heard, and the little motherboard speaker has been plugged in. And my monitor doesn't get a signal. Anyone know what the problem could be? I just bought everything new, so I doubt its a hardware issue. Have I missed something I should have plugged in somewhere? Also, I've tried putting my stick of RAM into each of the different slots, and it hasn't worked for any of them.
