Got this a few days ago, suddenly stoped booting into windows

Basicaly this is what happened.

I was playing Battlefield 2 bad company today, everything was fine, then I stoped playing and I closed the lid (the pc went to sleep) then a bit later I opened the lid but it stuck on trying to come back from sleep for so long that I decided to "hard" power it off, which is just pressing the power button for a while until it turns off.

skip a few hours, a few minutes ago I try to turn the pc on and now it takes me to the "Windows couldnt start up properly bla bla" and gives me the usual 2 options, Launch with windows repair or Initiate windows normaly. if I try to go into windows normaly it just loads windows then reboots, never takes me to the windows start up screen. If I click the start up repair thing, it starts to load the windows setup files but after 3 seconds it takes me back to the options screen.

So I went to the extra options where I have the option to start in low res or start in safe mode etc.

I tried to start in the "last known configuration that worked" and it still rebooted the machine.. basicaly every option rebooted the machine, except safe mode. But here is the kicker, safe mode bluescreens before going into windows then reboots. In other words, I cannot log into windows and I do not own an external optical drive so I cant boot with the cd I got.

I know there is no way to go to alienware respawn from boot the way I could on my old M15x can I?

Anyway, I have no idea what happened, I've only owned this for 4 days and I didnt install any new hardware or anything. the only thing I did on it was uninstall mcafee and install battlefield 2 bad company. I did install bit defender but I am pretty sure that is not the problem as it has been running perfectly for 4 days until this happened.

It hasnt been in any extreme temperature situations.

Now I am not worried as I purchased the complete care waranty from dell so I will give them a call tomorrow, even though I am sure I could fix this if I had an external cd drive.

Any ideas? this is pissing me off to no end, I had a friend coming over today and he was bringing his laptop and we were going to do some battlefield and I am going to have to cancel.. my wife already gave me the "i told you not to buy alienware again" speech, as this is my fourth alienware machine and the past 3 croaked at some point. The one reason I went with alienware again is because this is the first one I've owned that wasnt made in Miami before they were part of Dell. So now I have dell's support and warranty which is valid in my country, with door to door service, which is why i said I am not worried.

Please help me into trying to figure out how to fix this without an external optical drive.

Actualy I just remembered two more things I did with this machien.

I installed a desktop theme a few days ago and updated every driver 3 days ago. The machine still worked perfectly for 3 days before this happened today
