JohnHACK,
Have you made any recent changes ? e.g flashed BIOS, if so, you may have to clear CMOS setup and reconfigure.Quote:

JohnHACK,

BTW - I think this should have been posted in the Hardware forum
try reseating your RAM...bear in mind this is a 5 am answer and may not be correct but it can't hurt.
YEs a Question for thw Hardware Forum.. Also John Delet your other Thread in this Forum.. Be for we start calling you a Multi-Post-Whore....
AS FOR YOUR PROBLEM....
Read this Tutorial .. (I think you were given this link with one of your last problems)
Then let us know what hardware you have..
My first suspicion.. BIOS Backup or CMOS BAttery is dead..
Second.. You have the CMOS reset Jumper in the reset position (most MoBo's won't boot in this pos.. but some will)
Third.. Your MoBo is Fuxor'd
Hmm I thought that there was a couple of others.. kant remember..
Cheers
edit: forgot the url of the thread..(tired0
Perhaps you need to replace the CMOS Battery.
I've already change the batt, reset the jumper, and reseating the RAM, but that msg still display... I'm trying to press Del to enter the CMOS and F1 to continue but nothing responds.
the type of my m/b is Abit AB-BHC6
I've tried searching the ABIT site for your m/b but it can't find it. Google can't find it either.
heres a couple keys to press to enter the bios, however I don't know which one it will be, or if I even listed it since I don't know what kind of bios you have.
DEL
F10
F1
F2
Hell, press all the keys
heres a site that might help you http://www.bioscentral.com/
if it's not the battery then try flashing your bios.
If your able to figure out how to get into your BIOS, I'd recommend you try loading either the "Fail-Safe Defaults"* or "Optimized Defaults"*.. and then save & exit.
*Actual names may differ, but it'll be something like that
I'm pretty sure that when you get this error, it only loads defaults, it doesn't save them. As such, you'll the error on every boot until you force the system to write the new CMOS checksum to the battery.
But then again, I could just be drunk... never know really.. :P
Note: While flashing the BIOS will cause the CMOS checksum to be recalculated, it's a rather risky method of doing so, as flashing the BIOS can fail & a lot of motherboard manufacturers don't cover failed flashes under warranty.
A method to find out what key to press, that works on some mobo's is to disconnect the keyboard, when 'halt on all errors' is on, thus will display a message like 'Missing keyboard press, F1 to continue or F10 to enter BIOS' tada here you are, worked for me a few times... messages may differ so succes with this method is not garanteed.
To correct your checksum problem... try with another battery, reset your bios with the jumper, load to defaults, reboot and load your settings. Although I suspect your mobo to be faulty, you could do a flash but that can be risky... is it still in waranty? Do a RMA.
