Random crashes, no problems running memtest

Hi -

I'm running an AMD Athlon 64 processor on a ECS motherboard. I keep getting random crashes after I put in new RAM.

Now I know what you're all saying. It's got to be the RAM. Well I've run several successful runs of MemTest every time I run the computer, so I'm trying other things to rule out.

The thing that specifically caught my attention was "This error was reported by the CPU via Interrupt 18 ". I've heard this is a USB issue, so I disconnected some potentially offensive USB things.

Do you know of any other problem this might be?

Thanks in advance.

MACHINE_CHECK_EXCEPTION (9c)
A fatal Machine Check Exception has occurred.
KeBugCheckEx parameters;
x86 Processors
If the processor has ONLY MCE feature available (For example Intel
Pentium), the parameters are:
1 - Low 32 bits of P5_MC_TYPE MSR
2 - Address of MCA_EXCEPTION structure
3 - High 32 bits of P5_MC_ADDR MSR
4 - Low 32 bits of P5_MC_ADDR MSR
If the processor also has MCA feature available (For example Intel
Pentium Pro), the parameters are:
1 - Bank number
2 - Address of MCA_EXCEPTION structure
3 - High 32 bits of MCi_STATUS MSR for the MCA bank that had the error
4 - Low 32 bits of MCi_STATUS MSR for the MCA bank that had the error
IA64 Processors
1 - Bugcheck Type
1 - MCA_ASSERT
2 - MCA_GET_STATEINFO
SAL returned an error for SAL_GET_STATEINFO while processing MCA.
3 - MCA_CLEAR_STATEINFO
SAL returned an error for SAL_CLEAR_STATEINFO while processing MCA.
4 - MCA_FATAL
FW reported a fatal MCA.
5 - MCA_NONFATAL
SAL reported a recoverable MCA and we don't support currently
support recovery or SAL generated an MCA and then couldn't
produce an error record.

Debugging Details:
------------------

NOTE: This is a hardware error. This error was reported by the CPU
via Interrupt 18. This analysis will provide more information about
the specific error. Please contact the manufacturer for additional
information about this error and troubleshooting assistance.

This error is documented in the following publication:

VAL - MCi_STATUS register is valid
Indicates that the information contained within the IA32_MCi_STATUS
register is valid. When this flag is set, the processor follows the
rules given for the OVER flag in the IA32_MCi_STATUS register when
overwriting previously valid entries. The processor sets the VAL
flag and software is responsible for clearing it.

OVER - Error Overflow
Indicates that a machine check error occurred while the results of a
previous error were still in the error-reporting register bank (that
is, the VAL bit was already set in the IA32_MCi_STATUS register).
the processor sets the OVER flag and software is responsible for
clearing it. Enabled errors are written over disabled errors, and
uncorrected errors are written over corrected errors. Uncorrected
errors are not written over previous valid uncorrected errors.

ADDRV - IA32_MCi_ADDR register valid
Indicates that the IA32_MCi_ADDR register contains the address where
the error occurred.

BUSCONNERR - Bus and Interconnect Error BUS{LL}_{PP}_{RRRR}_{II}_{T}_err
These errors match the format 0000 1PPT RRRR IILL



Concatenated Error Code:

This error code can be reported back to the manufacturer.

I read somewhere a while ago that some AMD computers has a problem with SP3 and it shoudln't be installed on.
I do know that same problem exists in some AMD regarding a virus. restarts for no apperant reason every 1-2 hours or so.
I suggest you check for both.
I'll try and find that article for you.

here's the one for sp3 issues
