  1. Booting

    When I turn my pc on it has a screen theat says the following

    Cmos Battery low
    PS2 Mouse not found
    Cmos time/date not set
    Press F1 to run set up
    Press F2 to load defaults value and continue

    I can press F2 and boots to another screen and I have to press esc to continue to boot?

    I am running Vista Ultimate everything works fine after all that but my time and date stays wrong after booting.

    Any ideas

    Most likely you need to replace your CMOS battery. They do falter after a time. You can buy them at your local drug store. Open up your computer and on the motherboard is this round, flat, silver colored battery. It will have a number on it. That is the kind you need to get.

    Warning: Make sure the PC is totally shut-down and unplugged and make sure you are grounded because one spark of static electricity can fry your motherboard. I touch my power supply to ground myself.

    Here is the thing: Before replacing go into your BIOS and write down all your settings. After you replace, reboot and put your configurations into the BIOS that you have copied.

    You can set the time and date in your BIOS.
