Try replacing the power supply, if that doesn't work then replace the motherboard.

It's strange that the dvd drive gets no power. As rscole said, possibly the PSU. Have you searched for what the flashing LED means? It could be a motherboard warning, telling you what's wrong.

Fossie: ...Have you searched for what the flashing LED means? It could be a motherboard warning, telling you what's wrong.

It sounds as though it's stuck in Sleep Mode, for whatever reason. Which would explain the lack of power to the DVD drive.

However, that shouldn't be happening given that you have switched the power off at the wall and then tried to restart.

Most likely a stuffed motherboard in my view, failing that, a faulty power supply. Not what you want for Christmas

Also, have you made sure you got a surge protector? A friend of mine plugged her new computer in to the wall, and in less than 30 minutes, it blew right in front of my eyes. She got a new motherboard (without charge) and also a surge protector board.

Disconnect DVD drive and hard drives for starters, modern supplies do have overload protection.

I have had this problem before with my desktop computer running Vista! I once accidentally clicked on "sleep" instead of "Shutdown". When I tried waking up the computer, it wouldn't. I even turned it off and on at the front and still I saw nothing on the screen.

Scary stuff!

My solution? Turn off the power switch at the back of the computer (not the wall switch; the on/off switch at the back of the computer) and turn it back on. It should then work. Give it a go.

I also had a similar problem fairly recently, it was a hot day, the computer was over heating, and then BAM. It turned off. Teh really weird thing was after shutting the computer off and turning off the power supply, the HDD & Power led on the front of the case were still going.

Puzzled I then removed the power cable, nope. Lights still going.

Finally discovered that there was an external HDD plugged in (who put that there?!) and it was supplying power back into the computer via USB port!! Weird.

Okay, so unplug all USB devices you do NOT need. Only keep Keyboard & Mouse if possible. Then try turning the PC back on.

In our case we had to get a fan, open the case and have the fan blowing cold air into the case while in use (as well as unplugging the external HDD). Have not had any problems since! (even without the case off & fan blowing)
