It is best to keep the optical drive and hard drive on separate channels, as in on separate cables, but this sounds unrelated.

What you should do is go into the BIOS and set detection settings to Auto on the optical drive if it's not set as such already. If this does nothing or it is already set to Auto, then clear the CMOS. First shut off the computer completely and unplug it. There should be a small jumper down on the bottom edge of the motherboard that says CMOS next to or under it. Move the jumper so it covers the middle pin and the one that was previously uncovered. Leave it there for 30 seconds. Move it back to the previous position. Put the panel back on the tower, plug it in, power it on and see if this helps. If not, then disconnect the DVD drive and floppy drive. If you boot up fine and don't hang, then shut back down and plug in the floppy. If you boot fine, then it's the DVD drive. If not and it hangs again, then remove the floppy and plug in the DVD drive. If it hangs as well, you know that both may be interfering. This could be 2 bad products. If it hangs no matter what, then unplug the hard drive and boot (it should try to boot from CD). If it does fine with the DVD plugged in, then it is the hard drive and it may need to be replaced. Try another hard drive and see if it works fine with that.
