Last week I tried to install new SSD disk. And it doesn't detect by the system. so i tried to unplugged VGA card and existing HDD about 6-10 times. Still not working. So i tried to change the BIOS setting of the PCI setting and enable "compute" in all slot. After reboot, PC can't boot up and beep 6 times. According to the manual, it is because of the VGA card issue. So I reset the BIOS setting by removing battery, and pressing CMOS button. But it not working. Then I remove the jumper which is beside the CMOS button to "Crisis recovery jumper". After power up, it beep 8 times and come up with BootBlock Emergency recovery mode and show that System BIOS image is corrupted.
