It looks to me like you have lost your SATA controller on the motherboard. "Reboot and select proper boot device" means the system can't find any drives connected to the system. Since they are physically plugged in and powered up (can you hear them spinning?) this means that the problem is at the motherboard.
Based upon the other information you supplied there are a couple of possibilities. But first off, have you made any recent changes to the PC (added/removed components)?
But in all cases like this it is important to start with the basics. First we need to determine why you can't enter the BIOS, which is an independent function that does not rely on the drives.
So first I would disconnect all hard drives and CD drive SATA cables, then boot. See if you can get into BIOS.
If you can get in, then add just one drive back and test again. If that works then test the other drive (alone). Then add them all again. Report here the results of these tests.
After these tests are complete you should try a ClearCMOS procedure. This will reset the BIOS and force it to rediscover the components in the system. Note: CLRTC and ClearCMOS are the same thing. Refer to your motherboard manual to find the ClearCMOS jumper.
- Shut down the computer > remove the power cord.
- Remove the 3v battery.
- Move the CLRTC jumper from pins 1-2 to 2-3.
- Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.
- Put the CLRTC jumper back on pins 1-2.
- Replace the 3v battery > replace the power cord > boot.
- Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.
