Ram suddenly not being detected
My computer was running fine and dectected my 1.5g of ram, then all of a sudden after I restarted, I noticed only 1g was being recognized. I tried swapping out a couple different sticks of ram (as well as trying the ram in another computer, and they are all functional), and it seems all the sticks work as well as all the slots, but my computer won't recognize all the ram that is in there. Anyone knows what the problem could be? Could it be something happened to my motherboard and it only recognized 2 out of the 3 slots?
Forgot to mention, the sticks are from different manufacturers, but they are all PC2700 DDR333 Ram.
