Hello.
I have done everyhing you ask me to..
Ram was ok, no errors..
Clean all: ok
I have also updatet Bios but i get this " CMOS checksum error"
I am not able to clear cmos data with the cmos jumper. Tryed many times...
I have also disconnected the little battery for about 1 hour, but it still the same.
Anybody know what i can do?

Can it be that the battery is empty?
I have tryed to replace it with one that i had in the tv controller, but i dident help.
Maybe that battery is almost emty to...
JanTore , are you clearing the cmos jumper correctly ( remove from pins 1 & 2 and place on pins 2 & 3 ) for about 30 secs this effectively "shorts" the pins , then replace the jumper back on pins 1 & 2 :)
If the battery is almost dead will it 'short' the pins effectively?
A dead or dying battery can cause all sorts of weird issues, and will certainly cause the Bad Checksum error.
If you have an electronics shop nearby go and buy a new 3v CMOS battery. They're cheap.
Otherwise, enter the BIOS and Go to the Exit Tab and "Restore BIOS Defaults". That will clear the checksum error as long as the battery is good.
Load Optimized would be the one to try first. Then if that doesn't work try the Fail Safe ones.
Be sure to make note of you current and preferred settings on all tabs prior to doing this. You will want to set them back once you get rid of the checksum error.
