I recently found out that my BIOS/CMOS has been hijacked. I have a 500gb HD that I was going to replace and or even wipe but I first noticed that the monitor does not turn on until Win 7 starts up. when I tried to hold down or hit F8 of F12 the computer start up stalls (start up actually halts and does not do anything). I have tried with a new blank HD and I have a Win 7 repair disk but nothing is helping. I even tried to use the 'config' program in windows 7 for other boot options but no luck.
Yesterday I found a possible fix to remove the CMOS battery from the motherboard for factory reset but now I am not getting anything. computer just boots up to a blank screen and after about 10 minutes the computer shuts off like it would automatically when you set for power options. I have the CMOS battery out right now and am going to attempt another start up with battery back in.
Thank you for helping me with this matter. Lemme know if you need specs, I will try to get them.
