Thunderbird machine_check_exception errors

Have a Thunderbird 850, 128M Ram, GA-7ZX motherboard with VIA KT133
chipset.

Was running Win98 and had a lot of problems with system spontaneously
rebooting itself. Thought it was spyware which system was infested with
so
bought WD 80Gig HD and installed Win XP Pro.

Still reboots itself, and often get Machine_check_exceptions. Error
report
says STOP: 0X0000009C (0X00000004, 0x00000000, 0x2000000, 0x00020151)

Don't think it's heat, BIOS says processor 30 deg. C, system 70 deg.
C.
Heatsink is clean (was dusty a while back while on Win98, cleaning
didn't
help.

Ran MEMTEST for 9 hours, no errors found.

Reboot problem seems to come when using system more, graphics, games,
ect. but not always. Often machine check error comes when logging in as
a user.

Any ideas? What do the codes mean?

it never happens to me when i type ms codes into the google box but all kinds of stuff comes up on yours. (0X0000009C)

try running prime95 for a while. it stress the cpu.

you might install motherboard monitor 5. with it you can watch your temps and voltages while running prime95. there's a dashboard screen you can put up on desktop.

this should keep you busy. here's ms's thoughts:

CAUSE
This behavior occurs because your computer processor detected and reported an unrecoverable hardware error to Windows XP. To do this, the processor used the Machine Check Exception (MCE) feature of Pentium processors or the Machine Check Architecture (MCA) feature of some Pentium Pro processors. The following factors may cause this error message:
• System bus errors
• Memory errors that may include parity or Error Correction Code (ECC) problems
• Cache errors in the processor or hardware
• Translation Lookaside Buffers (TLB) errors in the processor
• Other CPU-vendor specific detected hardware problems
• Vendor-specific detected hardware problems

STATUS
This behavior is by design.

MORE INFORMATION
A machine check exception occurs when Windows XP and your hardware platform cannot recover from a hardware error so that the system can continue to run successfully and reliably. More specific diagnosis of machine check exceptions is difficult, and there is no general solution. Contact your hardware manufacturer or a computer hardware technician for help with troubleshooting this issue.

Machine check exceptions are frequently caused by one of the following conditions:
• You are running the processor or mainboard beyond its specifications. For example, you are overclocking the processor or bus. We recommend that you run your hardware at the manufacturer-rated speeds.
• Noisy power, overstressed power strips, outmatched power supplies and failing power supplies can destabilize your computer. Make sure that you have a stable, reliable power supply to your computer.
• Extreme thermal conditions caused by the failure of cooling devices such as fans may damage your computer. Make sure that your cooling devices are all working.
• You have damaged memory or memory that is not the correct type for your computer. If you recently changed the memory configuration, revert to the previous configuration to determine what is wrong. Make sure that you are using the correct memory for your computer.
Note Your hardware may support additional error logging features that capture the machine check exception and suggest a more specific solution.

The Pentium and Pentium Pro processors provide a mechanism to detect and to report hardware-related problems such as memory parity errors and cache errors. To signal a hardware error, the processor signals the detection of a machine check error by generating a machine check exception (Interrupt 1. Windows XP reports that the error occurred and displays parameters that you can use to decode the exception. Contact your hardware vendor or processor manufacturer for information about the Machine Check Architecture, or see the Intel Pentium Pro Family Developer's Manual - Volume 3: Operating System Writer's Manual.
