Unable to start PC in at all, even in safe mode

Hi All,

I am unable to start my PC in any mode. I have set the boot sequence to CD drive but I get a blue error screen with “A problem has been detected etc” finishing with STOP: 0x0000007B (0x0F89DB524, 0x0000034,) I suspect I suspect some malware somewhere & deleted some trojans yesterday but couldn’t get to safe mode to delete from there. I use windows XP. Any help appreciated
