When my coputer boots up it sometimes does not get past checking nvram.  What causes that problem?  I have changed the cmos battery and checked all the memery connections.  I have the current version of the bios but I don't no if re-flashing the bios will help.  The bios is AMI.  The motherboard is ASUS P4C800-E[/face]

   How often does it not get past nvram?

Hi Ray

Thanks for getting back to me.  When the computer hangs up on checking nvram I tried just using the restart switch but it would keep hanging uo on nvram.  I had to shut all the power off the unit using the switch on the power supply.  I waited 15 seconds and power it back up and it will boot up.  As of lately I have not had a problem but I am nervous that it will happen again.  When I started having problems it would happen every second or third boot up.  As I state in my previous message I did chance the cmos battery and thought I had the problem solved but it did hang up one time after the the battery change.
