Computer freezing up

  1. Hi All,

    I've been having intermittent problems with my computer freezing up. I bought and installed 2 x 1gb PC3200 ram modules. And I bought a Logitech wireless keyboard and mouse combo.

    Installed the combo and it all went sweet, no problems. Took the computer apart. I had 2 x 256mb ram sticks in pos#1 and #3. I added my 2 new sticks in pos#3 and #4. Plugged the usb wireless receiver back in and booted up. Seemed alright, put software CD in computer and it locked up.

    I restarted and it froze in about 5 seconds. I reverted back to my standard keyboard and mouse and got back to the software installation which required the receiver plugged in which froze the computer again.

    I restarted and removed the receiver but after a few minutes I got that blue screen memory_management error. So in the next reboot I removed the CD and it's been going good for at least 10 minutes.

    Can someone give me some suggestions? Could the CD have caused the issues?

    Also is there a specific way of installing ram? I noticed the 2 new ram modules were a little difficult to push down so the white clips locked. But all 4 definitely locked and both the system specs screen and the ram optimizer accurately register that I now have 2.5g ram.

    Thanks for any suggestions.

    Unlikely it's the CD itself, but maybe something that is loaded from the CD. Have you tried using other CDs to see fi the CD drive is the problem?

    It froze again without the CD in the drive. I don't think anything was installed off the CD.

    This time though there was no actual description on the blue screen. Instead it reference file win32k.sys. Any ideas?

    I reread your description and the only change you made that's left is the new RAM. Try removing it and see if the freezing stops.

    I want to leave the new ram modules as the absolute last option. I've taken out the 2 x 256mb modules and I generated the minidump for the original win32k.sys error. Can anyone glean any useful information from the following?

    This is a very common bugcheck. Usually the exception address pinpoints
    the driver/function that caused the problem. Always note this address
    as well as the link date of the driver/image that contains this address.
    Some common problems are exception code 0x80000003. This means a hard
    coded breakpoint or assertion was hit, but this system was booted
    /NODEBUG. This is not supposed to happen as developers should never have
    hardcoded breakpoints in retail code, but ...
    If this happens, make sure a debugger gets connected, and the
    system is booted /DEBUG. This will let us see why this breakpoint is
    Arg1: c0000005, The exception code that was not handled
    Arg2: bf82686a, The address that the exception occurred at
    Arg3: acf2bfec, Trap Frame
    Arg4: 00000000

    Debugging Details:

    EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at "0x%08lx" referenced memory at "0x%08lx". The memory could not be "%s".

    Time for the last option! Put the old RAM modules back in and take out the new ones! Let's see if the freezing stops! (I'll bet it will!)

    You new RAM might be flacky. It's not uncommon.

    I seem to have fixed it, hopefully. Everything is working smoothly including the wireless keyboard and mouse. I think one of the 2 unused slots that I first placed the new ram modules in were faulty.

    I had left the sides off the PC for quite a long time and I'm guessing that dust has settled into the unused slots. Is that permanent damage or can it be fixed easily?
