    Check your manuals to see if there's a jumper to reset the CMOS. If so that jumper might have been placed in the, "reset" position and every time you start your computer the CMOS will be reset thus rolling back your system to BIOS defaults.

Computer clock resets to 1 Jan 2002 when I switch off? How do I reset the BIOS to default?

When you get the BIOS POST screen you need to press either "f2" or "Del" then look for the "Default setting" selection. The chances are that the cmos battery has failed. a new one is very cheap and easy to fit. It about the size of a Quarter or a ten pence piece. Good luck.

Hello Saifthesmart51, Hi looks like you need a replacement battery for your motherboard, after replacement, set the time in bios or in windows. The battery looks like this. CR2032 cyberdyers_4.jpg

I have a 945GCT-M/1333 motherboard but my processor is a Intel Pentium 4 - 2.66mhz and it seems to run for a little while and then shut down the entire system. I am running a Ram chip 1GB speed 533MHz...

I always suspect overheating first in these cases. Are the fans, especially the fan on the cpu heatsink running?

You can check the system temperatures on most systems by booting the PC and entering the BIOS setup ....often by pressing the DEL, ESC or F2 key repeatedly as it starts up (the screen will tell you . which key to press to enter setup) . In the BIOS setup navigate to the "HArdware Monitor" or "PC Health" section. Watch the CPU temperature. On idle in the BIOS setup the temperature really shouldn;t go above 40C.

If it's a lot higher than this then the CPU heatsink fan needs attention.

Is the CPU fan spinning? have you tried a different VGA card? (though if it's a brand new board, I'd be taking it back as it'll still be covered by the warranty)

Intel Desktop Motherboard D845GRG

Hi Jan,

The drivers for your Intel D845GRG motherboard may be found here.

If the PC came with an add-on video card, you need to determine the brand/model that we may be able to get the necessary driver(s).

Please be reminded that drivers are OS specific.

Hope that this be of help. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
