I have recently purchased 8gb of ram to replace the 4gb I have in my pc at the moment. I followed all instructions I could find, and I'm certain that the ram is compatible with my motherboard. However when I installed it, my computer boots ( lights on, fans working, ect ) however the monitor says that there is no signal. I have tried each stick individually in every port possible, and still no change. I have also tried removing the cmos battery due to suggestions on forums, and again, still no luck. I also read on other posts that most people have installed their ram from before, and have the same problem. However when I installed my old ram, my computer worked the same as before. If there is anymore information needed please let me know. Thanks in advance.
