penitenziagite Posted January 23, 2011 Share Posted January 23, 2011 When booting PC, I got this message:CMOS/GPNV Checksum BadThe HD didn't appear in the boot device list. I booted the PC from Hiren's boot CD, and then I could boot normally.What does this mean? Is it the Mobo, BIOS, anything else?Thanks. Link to comment Share on other sites More sharing options...

ck_kent Posted January 23, 2011 Share Posted January 23, 2011 I usually replace the CMOS battery whenever I see an error like that. You could try that since it's easy and cheap, and set the date and the time correctly and see if the error still returns. I'm not saying that's always the case, but it's the easiest thing you could do to isolate the problem. Link to comment Share on other sites More sharing options...
OhMyGod Posted January 23, 2011 Share Posted January 23, 2011 You could have a faulty device connected to your system. Unplug all externals devices on your computer except for your keyboard and mouse and see if the problem still persists.Run CHKDSK- http://www.computerh...com/chkdskh.htm on your hard drive that has Windows installed on it. Also could be your BIOS battery or corruption in your BIOS settings. Boot into your BIOS settings and check your performance monitor if your BIOS has one.Check your boot device order to make sure that it is setup correctly.Good luck.:D Link to comment Share on other sites More sharing options...
