Alienware X51 R2 Corrupted Bios (?) What can I do?

This question is not answered


Apparently my little brothers 'desktop' broke down - he has the Alienware X51 R2 - it has had some driver issues in the past week which I resolved by starting safe mode and doing a rollback on the amd (r7 270)  drivers. The system is Windows 10.
Well, today the PC suddenly shut down while he was listening to music and, when I try to turn it on the lights will turn on, the fans spin - then a single (!) beep and it shuts down again, no text on the screen, no alienware symbol, no loading BIOS. 
From consulting the beep code explanations, a single beep means corrupted BIOS, no? 

So my question to you, and I would be very grateful, were you to answer it, is what I can do on my own to solve the problem - can I somehow force the BIOS to reset or install new BIOS, if the motherboard is still OK? Should I reset the CMOS battery? (Never done that) 

If all that fails and there is no other option, is a new MB viable?

Thank you in advance for your advice.

  • Hello Lamperouge,

    as the system keeps power cycling I would exclude the "1 Beep Error" as no valid error code. When a POST error code is audible, the system should stay on and repeat the code multiple times.

    I recommend you to exclude as many hardware parts as possible for you. You will find a general troubleshooting guidance for such problems on the following webpage:

    If needed you can find also a step by step guide written by my self in German language:

    With kind regards,


  • Thanks, I'll do that. I didn't look, but it's fine geographically; I just automatically resort to using English on the net. 

    Danke Also!
