And with the integrator when the pc restarts freeze in the Intel screen, and when i turn off and turn on again windows runs normal but i get this error "Flash update bios failure". I dont know what to do now i try everything and nothings works.
Hi try using the recovery method, it is usually teh most reliable: http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm
Before you do it unplug teh system completly form the power and remover the CMOS battery for 15 minutes or so tehn put it back in and do the BIOS uodate.
Aslo from what BIOS are you upgrading from?
