I installed win 7 home premium onto a new HDD. Everything went OK. I even activated windows but the computer boots only from the installation CD. When I enter bios and try to change setting to boot from the HDD everything stops. The keyboard is not working and the clock is stopped! Then I can only power down the PC. I switched keyboards but with no luck! When win 7 starts via installation CD everything is working fine. Do you have any suggestions to overcome using the installation CD for booting? Could the motherboard be damaged? It worked fine until the installment of windows.
