Hi all,

 

I have a problem with my Dell Dimension E521.  I installed wrong bios update (C521),

and i cant return it to E521. When i start my PC, I hear a strange sound.

When i start my PC with Windows XP cd , it starts normal. But i cant start always with Windows Xp cd.

 

When i start, i see the name C521 at BIOS.  I have try E521 bios updates, but it says unsupported system.

 

Please can anyone help me, i dont want hear a strange sound when i start my PC always.

 

 

Thanks!
