Hi I have just installed my motherboard and all pc parts into the new case (antec sonata 2) and the pc does not start up. Sometimes it starts only when I turn off the power switch and turn it back on after about half hour, the system then starts normally and then after a few hours it would freez up and I would then have to switch it off via the main power switch. If I hit the reset button on the pc all I can see is the two dvd drives lights go on and the drives make a reading noise and the screen goes blank with no beeps or bios. The power light comes on but no hard disc and the screen stays blank with just the 2 dvd drive's lights flash. I set the dvd drives to master and slave, used the two connectors from the IDE cable to connect onto the drive and I can't see why it's doing this. Can anyone please help?
