Two days ago HP's 'Health Check' recommended that to flash a BIOS and I flash the BIOS of our new laptop hp pavilion dv9000. During the update process(a windows bios flash), the system froze. I waited for several hours just to make sure it would comeback but not. I recycled the power and now I get BIOS ROM check sum error. The system is 15 months old so just out of warranty. Can I replace my motherboard? or any suggestion for me?
