Computer Keeps Freezing

  1. Hi all, recently i upgraded my computer with more ram. After the upgrade i turned the computer on and everthing seemed to be running fine. Then all of a sudden it randomly started to freeze completely. Nothing would happen when i moved the mouse or anything. I ran memtest but that found no problems. I am now wondering if it might be compatibility issue. I opened up the computer and checked the ram and noticed that the biggest 128mb module is ECC and the other 2 64mbs are Non-ECC. Could this be the cause of the system freezing? Or would it be something else?

    PC Specs:
    Intel Pentium III 800mhz
    256mb SDRAM
    250watt Power Supply
    32MB Nvidia GeForce 256 (DDR)
    1st HDD: 4.8GB Quantum Fireball EL5.1A (System Drive)
    2nd HDD: 10GB Seagate ST310014ACE (Backup Drive)
    Windows 2000 Pro SP4
    Motherboard chipset is Via Apollo Pro 133a

    Thanks, Nissanman

    you could try to run the pc on the single 128MB ram and see how that goes..
    Which was the original RAM (before the upgrade)?

    ok, i removed the two 64mbs and left the 128mb and it seems to be working fine now. Could it have been mixing the ecc with non ecc that caused the problem?

    That's a good bet. RAM is a tricky thing. When replacing RAM or upgrading, it's best to follow the manufacturer's specs in the motherboard manual and ALWAYS do it in matching pairs (sticks).
