Windows XP Pro - SP3 Freezing Randomly

By maolin34

  1. Have four of these with identical parts...

    Antec 4480 Case w/ 380W PSU
    XFX Nvidia 630i Geforce 7150 Mobo
    Intel Core 2 Duo E4500 775 CPU
    2GB Corsair XMS2 DDR2 800 Memory
    Lite-On 20X SATA DVDRW
    Seagate 7200.10 250GB 7200 RPM
    Windows XP Pro SP2 with Windows Update to SP3 current.

    Computer boots fine, opens programs fine. After sitting idle for a few minutes and it is frozen. Mouse does not move, no response to Ctrl-Alt-Del. Reboot required to restore. Have tried several things.

    1) All cooling fans are working.
    2) Swapped memory for a known working 2GB kit of OCZ Reaper DDR2 800.
    3) Re-installed Windows XP Pro from scratch.
    4) Installed latest drivers for chipset, video, and sound.
    5) BIOS is current.

    All of the computers are running the same software, drivers, etc. One different program, Cloud Desktop Spamfilter. Removed the software, still no difference.

    I am at my wits end. Help!

    XMS RAM usually works at higher than stock voltages. Maybe it's undervolted. Have you tried to adjust the voltage in the BIOS?

    I have not upped the voltages at all, the BIOS settings are at defaults...just as they are with the other three computers that do not have this problem. I did try other memory (brand) and still the same result. The 630i board is not dual channel, so I used a single stick of Corsair XMS2 2GB DDR2 800. I tried two 1GB sticks of OCZ Reaper DDR2 800, and some OCZ Platinum DDR2 800.

    At this point, I feel I have eliminated software, and memory...

    1) If it was the board, I would expect it would not even boot or have boot problems.
    2) If it was the hard drive, I wouldn't expect it to handle a full format, and re-install
    of Windows XP without a hitch, full updates to SP3, and install of about 15
    different programs.

    So, that leaves the PSU or the CPU....PSU sounds pretty thin, as does the CPU.

    Against what I have stated above, I'm thinking of replacing the drive.

    Advice anyone?

    I misunderstood. I thought you meant all of the PCs had the same problem.

    No overheating issues? CPU, PSU, graphics, etc.?

    Sorry, I wasn't clear. Only one of the four computer is having this problem.

    There have not been any issues with any of these computers until this one started freezing. It has been running since 7/08 without freezing until recently.

    I am trying to figure out what course of action to take at this point.
