I've got an X51 that a friend of mine gave to me. I originally had BIOS version A05, but while tinkering with the BIOS settings to try installing a non-Windows OS, I tried upgrading to the latest version, taking care to upgrade one step at a time and avoid the two versions with known issues; long story short, it was a bad idea. Basically, the PC tripped right out of the gate. The X51 was working just fine until after the BIOS update, but now when I turn it on, the buzzer beeps in three-beep cycles.
According to Alienware's beep codes, three beeps indicates a possible motherboard failure or chipset error. Nothing visual will load on-screen, so I can't use the BIOS to fix the BIOS. I also tried cycling the power and resetting the CMOS by removing the battery and toggling both the Clear CMOS and Password jumpers, all to no avail. I know the problem is an incompatible/corrupted BIOS. My question is, can it be fixed, or did I just brick the X51's motherboard?
I don't know if it's relevant, but the X51 I have doesn't have all of its original parts. I upgraded both the RAM and CPU to 16GB G.Skill Ripjaws X and an Intel Core i5-2500k up from the stock i3-2120.
