Need computer makers help.. error messege when i first boot my custom pc..


"Cmos checksum error - Defaults loaded"

Other than that, everything is beautiful so far! I thought the processor would burn and fry as soon as i fired this puppy lol.

I think there is an option to bypassing this error by pressing F1, but i dont know what I'll run into if I do that.

I almost looked over everything in the mobo handbook, but I cant remember any "Cmos" being mentioned, although, maybe they did. Does anyone know what this error indicates and how I would go about fixing this? Thanks

PS - People to helped me buy computer parts thanks again! Pics are coming

I have an old pentium 166 that I use for backup purposes. It gives me exact the same error message but adds the line: "CMOS battery failed". Since this is an old computer I can understand this and just press F1 every time it has to boot (that's not so often since it's running Linux). It forgets the date and time every boot. So maybe something is wrong with your battery as well...

CMOS is the memory in which your BIOS configuration parameters are stored (i.e. date/time, boot sequence, what onboard devices are enabled/disabled, etc.) A checksum error indicates the contents of that memory are corrupt. The usual cause is an improperly installed or bad battery.

edit: I need to type faster. Since this is a new mobo and lithium batteries last several years, if reseating it doesn't do the trick you should probably RMA the board.

I've had CMOS troubles before, more so on older PCs, but there are a couple things you can *try*, they might just fix your problem.
1. Pick up a new battery, places like Walgreen's / CVS have a great selection of special batteries.
2. Consult your motherboard manual, specifically the part which pertains to the CMOS reset jumper. Follow instructions.
3. Flash your BIOS, there is probably a new version available if your computer is getting up there in years.

Hope that I contributed something useful.
