Core 2 Duo 7400 Blue Screen of Death

By rosst3mp
Aug 7, 2009
  1. I recently started having problems with my PC freezing, at first it happened very occasionally and I disregarded it as a software flaw, however it became more and more frequent until I reached the point where I felt it would be a good idea to re-install Vista. It had worked fine for around 15 months prior to the problems.

    My Specs:

    Intel Core 2 Duo 7400
    MSi G33M Motherboard
    Unbranded RAM (2x 1Gig 800MHz)
    Radeon X1650 GFX Card
    Deskstar (is that the IBM brand?) 500 Gig HD

    (The machine is a Philips HEPC 7501, sold by PC World using the Philips name under licence)

    I had overclocked it, from 333Mhz FSB (2.67GHz) to 400MHz (3.2GHz). I always used CoreTemp and never saw temperatures above 50C. I pushed this back to standard to see if it would stop the instability - no effect.

    Tried booting to safe mode - no effect.

    Tried using different (known good) RAM - no effect

    Tried using different (known good) HD - no effect

    Tried clearing CMOS - no effect

    Tried using different (known good) PSU - got a "crack" noise on first power up, then it powered off, then powered on fine and then crashed as previous - no effect

    Tried using different power supply socket / surge protector - no effect

    Basically, it seems to be either the mobo, CPU, or GFX card. I can't test the GFX card as it does not have on board GFX, and I don't have another PCI-E card to use. As mentioned above, I tried to re-install, both XP and Vista, but the machine hangs even when running the installer from CD. The only error codes I managed to retrieve were from when I was running Vista:


    Shut down unexpectedly

    Problem signature
    Problem Event Name: BlueScreen
    OS Version: 6.0.6002.
    Locale ID: 2057

    Files that help describe the problem (some files may no longer be available)

    Extra information about the problem
    BCCode: 124
    BCP1: 00000000
    BCP2: 864A5028
    BCP3: B2000040
    BCP4: 00000800
    OS Version: 6_0_6002
    Service Pack: 2_0
    Product: 768_1

    I wouldn't mind upgrading the CPU or GFX card, but want to know if anyone can advise what is most likely to be the issue? If it's likely the mobo - then my GFX/CPU upgrade will have to wait!

    I cannot interogate any of the dump files as I tried one last re-install and it always crashes during install now, so I am stuck with nothing. I am loathe to take it in to PC World (where I bought it) as they charge through the nose for this sort of thing, and I have built and repaired many PC's in my time.

    Any advise appreciated as always.

    Guess I found what made the "pop" noise!

    One of the transistors, underneath the CPU cooler. Looks like it's time for a new Mobo.
