Hey guys, I need some help with my newly assembled system. The system specs as follows: Intel Xeon 3360 S775, DFI Lanparty X48 T2R DDR2, Corsair Dominator DDR2-1066 4GB DHX, Palit Revolution 700 HD 4870X2, Antec 1000W Quattro PSU, Antec 900 Case, Western Digital 320GB HDD, Maxtor SATA Diamondmax 9 120GB HDD. When I started the system, the LED display went through all the codes and it stops at Code 7F. From what I understand, 7F means it's a Bios Checksum error. I tried pressing the EZ Button (both) for 5 seconds to clear the BIOS settings, and still 7F. Pressed F1 and it went to FF, but nothing responding. The card is already seated properly.. or I guess (gonna try in a minute again) More of the bad news is I'm going to use this rig for tomorrow's Lanparty and if I could solve it tonight then probably I would also have the time to setup (format) the pc! Help guys!! I'm getting nuts already! EDIT: Tried the reseating of the card. Still nothing! No nothing at display screen.
