Hello guys I have the same problem with my Asus P5gd1-vm
It wont boot up. No Display. NO beep. But when I remove the memory it will beep those error codes. I dont know what to do next. I'm electronics Tech. I consider myself pretty good with computer. I checked the CMOS BATTERY VOLTAGE, Power suplly Voltages. They are good. But this one is a headache for me. I suspect anyway that the motherboard is damaged. My memory is Samsung ddr400. The exact model of memory is not on the APPROVED LIST according to Asus. Could this be the problem?And could this motherboard to picky with memory? By the way my retailer warranty is over. I dont know how much hazzle or how long Asus will replace this board if i send it. Thanks guys, for any help.
