My computer randomly freezes, crashes and restarts.

  1. Ok, it sounds silly but it does exactly that. Sometimes it restarts itself, sometimes it just freezes and sometimes it gives the BSOD. Totally randomly. It may happen few times within one hour or it may not happen for a day. Usually it happens few times a day.
    Here is what I have done:
    1. Cleaned all the dust.
    2. Tried to remove memory sticks one by one and run with just one of them. If I only have one stick it crashes less often but still does.
    3. Run memtest with one memory stick. After 30 passes still no errors.
    4. Upgraided from vista to windows7 ultimate.
    5. Checked power supply voltage - OK. Re-checked next day - still OK.
    6. Checked processor temperature with everest and speedfan. Looks OK though T goes up to 47-50 the maximum is 55 for my Athlon 64x2 5000+.

    Don't know what else I could do... Here I attach 5 latest minidumps and I would really appreciate any help.

    Are there any yellow exclamation points in the device manager?

    Tmagic,
    Thanks for reply. There is nothing unusual in the device manager. No yellow exclamation points...

    "Upgraded from vista to windows7 ultimate"...
    So this freezing was with Vista too?

    Yes. This started with vista.

    So then this is a hardware problem then... Not a software or driver issue, or maybe a it's a software personal choice

    I wouldn't argue with that...
    My main question is how to locate and fix the problem?

    I added to my last reply, any software used on Vista and now on Win 7?

    Don't know if this will be of any help, but I also noticed that if I'm logged in as administrator it crashes/freezes more often than if i'm logged as user...

    Nothing special. I have MS office, photoshop, Mozilla etc. No games of special applications...

    Update. Actually on vista I had LabView and Visual Studio. But I did not install them on windows7.

    Is the computer's inside clean and are all the fans working normally

    Yes. The very first thing I did - I cleaned off all the dust. Fans are ok.

    Maybe a weak power supply?

    "If I only have one stick it crashes less often but still does"...
    Reset the bios to the defaults, then replace the memory errors or not

    Just did.

    Sorry, I didn't get this...

    Memory is cheaper than a motherboard if the bios default doesn't prove anything

    OK. So, you think it is either memory or motherboard?

    By the way I left the computer running overnight and it did not crash (yet)...

    "By the way I left the computer running overnight and it did not crash (yet)"...

    The bios reset might have done the trick in getting rid of the BSOD's

    Resetting bios did not help. It froze again...

    I'm leaning towards a bad motherboard, but as I said, memory is cheaper to replace

    Tmagic,
    Thanks for your help. I will look for the new motherboard. You are not the first expert who blames the motherboard and I think it makes sense...
    I appreciate your advises and at least after resetting bios it does not freeze/crashes that often...

    Just a quick update.
    The problem was a bad motherboard. I installed a new one and for a week had no problems at all.
    Tmagic, thanks again!

    If it freezes, I'd blame the ram but I'm not an expert, just personal experience.
