Exist some problems that can cause that: 1- The CMOS battery. Solution: Change it for a new one. 2- Some problem with the time specifications in the BIOS. 3- Some drive that isn't connected properly. ahthurungnone August 12, 2010 11:57:23 PM I reset the bios and input the correct date and also reconnected the main drive to the mobo. Everything is fine now. Thanks.
