cmos button pushed numerous times without effect, window 7 cd inserted - no startup-black screen-motherboard cd inserted with crashfree bios program but no startup-black screen, hard drive spins up, fans spin, usb slots work prior to board lighting up like a christmas tree has to mean all the voltages and settings are off....possible reason for initial lack of detecting dram?
