    8460p with motherboard 161C KBC version 97.4B (with ATI 6470M) BIOS 68SCF vers. F.27. CPU i5-2520M. Need upgrade CPU to i7-2720QM ES. After replacing processor - system was booting, I hear sound after windows start up, correctly shutdown, but during this I can't see anything on display. How to init display (ati 6470M may be instead internal intel HD 3000?), or add full support CPU into BIOS?
