I have a dell dimesion desktop, with pentium 3.2ghz, 2 gb ram running XP sp3.
Since yesterday, it wont boot up from the power on button, but if i clear the cmos, it will autoboot. it will restart ok once booted, but if i shutdown, i have to clear cmos again before it will start. However, after i insert the power cable, all the lights come on for just a second then it dies. I have tried playing with the RAM but to no avail. Is there anyone who knows of a similiar prob ?

This a neither Windows problem nor a CMOS Battery Problem. It is problem with Motherboard BIOS. You get your bios upgraded or Check Motherboard for any shorted near CMOS Battery and Jumper.
Thank You.

No, when the battery is busted the CMOS is cleared every time u shut off the computer.

I think somethimg in windows is corrupting the Bios settings.
Try a System Restore to the point just before this issue began. http://www.microsoft.com/windowsxp/using/setup/support/sysrestore.mspx
