  1. heres the story
    the problem started when my twinmos speed premium rams start causing my system to reboot randomly
    so went to rma,they verified it was bad,got it changed,went back and it was ok
    then one week later,the problem came back again
    so i went to test my abit is7-e at the tech support,it came out fine for the ram slots,the rams were ok too
    so i got my rams changed just in case,a few days the reboots happened again
    so i changed to kingston rams
    now it still happens,so its not the rams so what is it???
    my temps are ok,i got all my fans,including the northbridge one running
    i put my rams in different ram slots just in case and upped the voltage to 2.65v
    i havent installed any new hardware for a long time
    im running on NOD32,Sygate firewall

    my system specs at the moment are

    Abit IS7-E+P4 2.8c Ghz
    Kingston ValueRam DDR 512x2 CL2.5
    1xWD40GB,1xWD80GB
    ATI Radeon 9800XT
    Audigy Soundcard
    Verudium 450W

    i am in need of help because i dont know if its the PSU or the memory controller or software problem

    Hi,

    When do you replace the faulty ram? Before 22th Sept? As one of your minidump taken on 22th Sept was crashed at IRQL x'1C' which is clock level interrupt. This is the symptom faulty hardware. Most probably it is faulty CPU or RAM. The RAM is replaced so the L2 cache memory of CPU maybe the culprit.

    BugCheck 1000000A, {2000, 1c, 0, 804e1637}
    Probably caused by : ntkrnlmp.exe ( nt!KiUnlinkThread+7 )

    Suggestion
    Downclock the RAM.
    Check whether the RAM is compatible to the motherboard

    i changed to kingston 8hrs ago
    and after that,while playing warcraft3,the reboot occured
    prior to changing,the reboots were related mostly to running a bittorrent app called Azureus,which is closely related to rams;or some random reboot

    when i changed the rams to kingston,i switched the ram slots as a precaution
    im running the rams as DDR400 CL2.5 timing 3-3-8 which is perfectly ok

    Hi,

    You have three alternative
    1. Downclock the RAM and clean the dust within your PC
    2. Change CPU
    3. Call Mircosoft

    are u saying that even before changing to kingston,the root of the problem was not even rams?

    It is hardware error. It is no harm to downclock the ram for problem verification.

    If you want the detailed explanation of your problem, call microsoft. Microsoft develop windows and they should be able to find out the culprit.


    I use trial and error approach to diagnostic your problem and I cannot guranteer my recommendation is always correct. Hence my suggestion
    1. Downclock the ram
    2. Change CPU
    3. Report the problem to Microsoft.
