Remove ALL media from the machine DVD, CD, USB, etc. Check/reseat all Monitor cables. Reboot. If that fails, unplug , plug back in in 30 seconds or so. reboot, if you get a Dell Logo, Open the boot Menu and select Boot from HDD first.

The CD Drive has probably gone bad. You will have to buy a replacement drive. I recommend newegg.com. The price will be about 30$ for a DVD burner. If you want just a DVD player or CD Burner then it will be even cheaper. Dell provides a very easy to read step by step guide with pictures on replacing your drive here:

You clearly have an SMPS(power supply issue). Not 3 days ago I worked on my dad's PC that had the same problem. I found that the board had some leaky caps, and the circuit board inside it partially burnt. I could get it working by replacing the caps, but dont know how long it will last(I'll be getting a new PC soon anyway). Its advicable you replace the power supply. Should cost you around 30-50$ at MOST!

could be a bad driver..try booting into safe mode F8

The blinking yellow light on the power button is almost always a power supply failure of some kind. You should try disconnecting the PC from the wall and letting it sit for 10 minutes to let all the power in the capacitors drain. This will do a mini-reset on the power supply. Plug the power back in and then try it again. If that doesn't work, find the 110/220V red switch on the power supply, unplug the power from the wall, flip the switch a few times, make sure it lands back on 110, then connect the power and try turning it on again. If those don't work, you'll need to replace the power supply unit.
A solid green light means the computer is operating normally.
A solid yellow light indicates the power supply is operating normally but the computer is not processing data.
This could mean there is a problem with the CPu or another component on the motherboard.
((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))
A blinking green light means the computer is in standby mode.
You should consider visiting Dell Support and downloading the manual for your
your Dell computer. So use the LED power light codes if your Dell computer has them.
hope this helps
