My Inspiron 8100 will not complete the load on the BIOS screen. I was getting a bad memory error with F1 to shutdown and to remove the one closest to the front of the machine

I have taken in and out all the cards I can find. Even the video card just in case. No luck. I've booted without one out of the two memory cards in it (someone else suggested that on another site) and it still does it. Any suggestions? :emotion-9:

After about 10 minutes the computer just shuts itself down.
