I'm having the same issue. I've been looking for a solution and haven't seen one yet.

Ive just send it for repair today, i couldnt even press f12 there was no respond what so ever, thanks anyways

So basically the computer isn't booting into Windows.
My best advise at the moment would be to start by running a Preboot-System Assesment.
In order to perform this, you must start your computer and tap F12 to get into the Boot Manager.
Near the end of the screen there should be an option that says Diagnostics, PSA, or EPSA.
Please run the basic test (Without running the Extended Memory test... which takes like half an hour). And tell me what you got.

I'll await both of your responses.

It's like the computer freezes towards the end of the post inabling me to hit f12.

Iwas at the tech center today they told me the cpu was not working and the whole system had to be reinstalled..

Did they happen to give you a suggestion on how to do that?

wonderful

I was reading more about the beep errors during bios but i know for a fact my beeped from day one so i thought it was normal.

They said a new cpu were required and it would cost around 300$ for cpu alone because the current cpu in alienware x51 is no longer to be bought

Pretty sure its suppose to say that beep one time on bios screen
