I have purchased a new Asus motherboard, (P4V8X-MX) and a celeron D 340 processor. I installed it and hooked everything up making sure it was right. When I turn it on and try to get into the bias, all I get is a blank screen. I know the monitor is ok as I unplugged it and hooked it up to my other computer. I already went through all the steps that were in the trouble shooting guide in this forum and still have the same problem. The motherboard is sitting on a peice of cardboard, so it's not shorted out to the case with only the cpu/heatsink and fan, one stick of memory in the main slot, the mouse and keyboard connected, the wires for the power switch and of course the monitor. I have pulled the battery and moved the jumper to reset it, moved the jumper back and installed the battery and still nothing. I double checked the processor installation and of course used some heat sink compound when installed. I don't know what else it could be or what I can try. Any ideas out there or if you had this problem yourself or heard of it before, please let me know. It's definitely frustrating and disapointing to say the least. Thanks for your time and help.
