K7S8X's BIOS P2.30 doesnt start...

Question

when I turn on the PC the start up is blocked at the display of :AMD Athlon(tm) XP 2000+ (133x12.5 CPUID :0681)I have tried to clear the BIOS with the jumper clrcmos2 but when I shutdown the pc again later it has the same problem on the restart. the power is on but nothing seems to go on. I have this problem for the first time unexpectedly, the computer restarted by itself.where is the problem?! a BIOS upgrade is needed or is a kind of virus?need some help...
