Networking problem - My computer shuts down.

  1. ----------------------
    Here is my Situation:
    ----------------------
    My computer#1 is unable to finish the job to SEND/TRANSMIT data (via a LAN) at 100 MBps full duplex mode. Whenever I begin to transmit/send data (example: copy and paste files) from computer #1 to computer #2, computer #1 crashes/restarts/shutsdown within the first 5 seconds +/- of data transfer and this only happens if I do the SENDING in 100 MBps full duplex mode or higher at either computer. But Computer #1 will RECEIVE data fine at any speed including 100MBps full duplex mode. PLEASE NOTE that Computer #2 is perfectly fine and does not crash/restart in any transfer mode or situation. The problem I have is with computer#1.

    -------------------------
    Here are the Symptons:
    -------------------------
    As soon as computer #1 crashes/restarts, I got the BSOD (blue screen of death):

    "*** STOP: 0x000000D1 (0x00000000 ,0x00000002, 0x00000000, 0x00000000)
    DRIVER_IRQL_NOT_LESS_OR_EQUAL

    Beginning dump of physical memory"

    OFTEN the computer restarts cold, sometimes it simply shuts down, and rarely it gives me the BSOD.

    ------------------------
    Below is my diagnosis:
    ------------------------
    By process of elimination, the NICs, the slots, the sound card, SCSI adapter, video card, the RAM, the IDE cables and the voltage supply to the OC'd CPU are not causing the shutdowns. However, I've not fully tested the OC'd CPU as to whether it is too hot due to lack of cooling. So those 'could' be the culprit or is it something else like a defective CPU? BTW, I've put the CPU at stock speed (366mhz) and the problems "seems" to be gone but I've not fully tested in that area either. Please post feedback if anyone have had experience with this particular problem.

    -------------------
    Here is my Setup:
    -------------------
    Proper LAN hardware connections are fine and both computers are able to communicate normally through file sharing and browsing with no problems. There are only:

    1.) two computers within this LAN,

    2.) using a LINKSYS BEFSr41 v1.46.02 Router,

    3.) two Gigabit NICs
    (D-Link DGE500T for Computer#1
    Netgear GA311 for Computer #2),

    4a.) D-Link DGE500T general properties:
    normal settings-------------------------------
    Client for Microsoft Networks.....[checked]
    File and Printer Sharing............[checked]
    Network Monitor Driver.............[checked]
    Internet Protocol (TCP/IP).........[checked]

    advanced settings-----------------------
    Jumbo Frame Size........[Value = 1500]
    Network Media.............[Value = 100 Full]
    [ALL other values = default]

    4b.) Netgear GA311 general properties:
    normal settings-------------------------------
    Client for Microsoft Networks.....[checked]
    Network Load Balancing............[unchecked]
    File and Printer Sharing............[checked]
    Realtek LANPkt Protocol............[checked]
    Network Monitor Driver.............[unchecked]
    Internet Protocol (TCP/IP).........[checked]

    advanced settings-----------------------
    802.1Q VLAN ID........................[value = 1] [defualt]
    802.1Q/1p VLAN Tagging............[value = Disable] [defualt]
    Jumbo Frame.............................[value = Enable]
    Link Speed/Duplex Mode.............[value = 100Mbps/Full Duplex]
    Network Address.........................[value = Not Present] [defualt]
    Offload Checksum........................[value = Enable] [defualt]
    Offload TCP_LargeSend.................[value = Disable] [defualt]
    WakeUp on ARP/PING...................[value = Enable] [defualt]

    5.) blue cat5e cables for both computers

    6.) Computer#1 is a ABIT BH6 (440BX chipset) mobo,
    with 32-bit PCI slots,
    PII 366MHZ Intel Celeron MMX (SLOT1) OC'ed to 458MHZ at 2.30V,
    cooled w/ dual 80mm fans
    (128MB DIMM +128MB PC100 +512MB PC133) = (384MB DIMM),
    FYI this mobo has a maximum of 128 MB per slot
    Windows 2000 Professional,
    I am sure I am not running any software that could be the problem such as firewalls, anti-viruses programs, spy/malware, etc. My processes list is very clean and short (13) and only has the crucial system process/files running.

    7.) Computer #2 is a ABIT VIA VT82C694X (Apollo Pro133 Chipset) mobo,
    with 32-bit PCI slots,
    PIII 1.0 GHZ (SOCKET 370 FC-PGA) OC'ed to 1.2 GHZ at 1.8V,
    cooled with a 120mm fan and aftermarket heatsink
    512MB PC133 + 512MB PC133 = 1024MB PC133 total,
    Windows 2000 Advanced Server

    For now, I will post this up for anyone to contribute any advice and help and/or feedback. Let me know if there is anything I should mention that is important. I'll look into other possible solutions along the way. I will post my findings later. THank you for taking your time to read all this and very much appreciated in advance to those who advise.

    EDIT*: I have latest W2k Pro SP 4, latest BIOS/MOBO firmware version.

    Hi

    Can you install different mobo drivers to test?

    I really have no choice but to keep the latest mobo drivers because they enable the mobo to read HDs that are 60GB and over while my primary HD is 60GB. If I revert to the older mobo drivers then my mobo will not be able to recognize any HD 30GB and over. Besides, the ABIT website offers one set of drivers newer than my original mobo firmware.

    But the odd thing is that I just recently was able to succesfully xfer the data as soon as the windows is logged on. But if the windows sessions has been on for quite awhile like maybe 2 hours + and I begin to send the data, the problem persists again. Could it be heat generation? In that case I'll try blowing my 16inch desk fan into the case and see if heat is really the cause.
