Adding memory to my computer running windows xp.

[Guest]

I added 256 RAM, along with the 128 RAM already there. Everything worked
fine. So now I have 384 mb of RAM. Today, I added another 256 RAM, same make
and model, but my computer goes crazy. My Dell troubleshooting guide says I
can max at 768 mb and covers what needs to be done for Windows 98 and NT, but
not XP.

Can anyone help me please?

Try a diffrent slot for the new memory,with a P4 board with 4 slots,1 & 3
must be the same size,with yours,try 256 in 1 & 3,put the 128 in 2.

In fact, I don't suggest you mix defferent size RAM in the PC, you had better
install the same memoy for stablility.
