Hey peepz need some help. My pc has stopped working out the blue. when starting up i'm getting the above error and the pc is not booting up. I have a asus motherboard running vista 64 bit ultimate. I don't have a recovery disk. I have tried to boot up in safe mode but when I press the f8 key it only give me the option to pick which drive to load from but still get the same error what ever I pick, don't get the boot in safe mode option. checked the bios and the hard is showing but just doesn't want to boot up. I have tried change the sata cables to the hard drive but no joy. don't know what else to try. any help would be appreciated.
