First check memory to see if it is causing a problem.Change memory out from a good machine if possible.
If its the CMOS battery that has failed,you will have to replace it with a new one on the mother board,Removing the battery will cause you to lose all Bios settings.
To replace the battery,you will want all BIOS settings recorded from the control(F2 or Delete)at the start up screen,you need this info to reset the settings after the battery has been replaced to make a less difficult transition.If there is a Manufacturers hand book it would be better,all the CMOS control panel settings are in it.Remove the battery from the motherboard and take to computer store with you so that you can get the exact battery.It would be a good idea to down load a upgrade to your bios before starting this process.
Good Luck

Hi,

I would suggest that you shut down you computer system, and unplug the power cord from the computer. Open up the computer, and remove and reseat one memory chip at a time if you have more than one chip.

If you do not know how to do this, maybe you could ask a friend who knows how to do this.

The constance temperature changes in the computer can make the contact work it way loose from the slot. I would try this first, before any other solution.
