Hello all, I'm hoping someone can shine some light on this problem.

Recently my dell inspiron 2600 notebook started locking up and BSODing randomly.. Upon the restart from one of these failures, the computer would refuse to POST, and would emit a beep code of 1-3-3-1. Dell tech support identifes this as a "motherboard failure" however they refuse to elaborate. On a hunch, i removed one of the two sticks of 128MB SDRAM and ran on a flat 128MB. When running on a single stick of RAM, the computer runs fine, aside from being terribly overburdened by lack of RAM. however when both sticks are installed, the computer will always fail by locking up in windows, having the LCD completeley black out and lock up. Refusal to post, or BSOD/locking up at boot-time. I have done numerous RAM troubleshooting steps such as swapping sticks and slots to verify that i didnt have a "bad stick" and i have verified that both sticks are indeed 100% good. Also, both slots are confirmed good as well. This is definietly an issue tied to the physical RAM, slots, or amount of ram itself. The only thing i can think of is that the motherboard is having trouble handling more than 128MB of ram.. does anyone have any ideas?? sorry about the long post, i wanted to make sure i documented everything ive done so far though..

Thanks,
