Your minidump history that you has given here shows the problem since 30 Dec 2007.

Aa okay.

Wait a minute

i got into this web > http://www.biostar.com.tw/app/en-us/mb/index.php

But i do not know which to download for my mother board + i cannot find where to dl it.

Please advice, once again.

Please identify your BIOSTAR motherboard model number. The previous report can't say more about your motherboard model

You can use CPU-ID software to look for this info.

Here's my info
Motherboard

Model : i845GV-8712F
BIOS : award soft international, Inc.
Version : 6.00PG
Date : 09/03/2004

So now what  ><

Huh, can you look on your motherboard physically for the model number. The one you see just now only reveals your i845GV chipset.

I've found the section in which i can download
In biostar..

Intel 845GV

P4TPT  and P4TGV

Which should i dl?
*
Your chipset is 845GV. So, P4TGV is the correct one.

Alright i've downloaded it..

But i cannot seem to open the file. ( . BIN )

Is there some way ?

Or should i save the file to somewhere?

Are your sure your motherboard is from BIOSTAR?

No, you need to use BIOS Flash utility to flash your BIOS with new data (.BIN) . Be careful and read instruction properly on how to use it to avoid you from "bricking" your BIOS and system. Most importantly, make sure you are connected to a stable mains power supply and wish that your house is not facing black-out while updating your BIOS. sweat.gif Close all anti-virus, anti-malware programs and other applications.

This one runs from Windows environment.

Read this first!

The previous link says that Biostar BIOS has the option to flash the BIOS while in the BIOS setting environment rather than in Windows environment. This is only true for recent motherboards but not for legacy motherboards.

Then, use that BIOS flasher utility that can run under Windows environment.

Hello, horcruxes.

I revisited your problem.

Microcode or microprogramming is like designing a "firmware" for microcontroller (MCU) or in this case, Intel CPU Pentium Prescott. There is a small size of programmable grid arrays (PGA) in Intel CPU Pentium Prescott. This "small" software (low-level coding), is emulating certain hardware functionality. Why Intel decided to create a microcode to emulate CPU hardware-level functionality is beyond my limited knowledge.

It seems that this microcode is unstable, maybe due to excessive heat which causing the memory area that stores this microcode to accidentally erase the microcode. That is why your crash reports keep showing zero-length CPU microcode bucket error. The memory area is quite volatile. Or, the way the user programs are using this microcode memory is triggering the crash.

QUOTE
Microcode updates are not stored permanently within the processor; they vanish when the power is cut, so every boot has to re-assert them.

....

If you have a Celeron with 256k Level 2 cache, or a Pentium 4 with over 1M of Level 2 cache, you have a processor that may be at risk.  In addition to this, if the revision level is less than 8 (in some cases 7; typically it will be 0) then you are definitely at risk.

.....

How do I get out alive?

There are two ways; one that allows you to uninstall SP2 and carry on as if nothing had happened, and another that lets you keep SP2, with one file out of use.

Disable Level 1 and Level 2 cache in CMOS

This will leave the system running so slowly, you will often think it's crashed!  Have faith; XP will load fine, and you will be able to go to Start, Settings, Control Panel, Add/Remove Programs and uninstall Service Pack 2 from there.

Expect this to take some hours; when it's done, shut down the PC.  On the next boot, go back into CMOS setup (the magic keys to do that vary between PCs; Del, Ctl+Alt+Esc, Ctl+Alt+S, F1, F2 and F10 are good guesses), find your way to where you disabled the Level 1 and 2 cache last time, enable these again, save settings and quit.

This is exactly what I did (thanks Cari for the tip!) and it worked fine.

Rename away Update.sys

For best results, keep a copy of your old pre-SP2 Update.sys somewhere else before you install SP2.  To find the file, navigate Windows Explorer into your Windows base directory (typically C:\Windows), then into System32, then into Drivers.  You may have to change settings so that Windows Explorer actually shows you these things!

After you install SP2, and the system can't boot Windows anymore, etc. then fire up your maintenance OS, find the Update.sys file as described, and rename it away.  If you kept the old pre-SP2 copy, then copy that back in as Update.sys - that is currently how I'm running my test PC, and time will tell how well this works.

Note: Running XP, perhaps especially with SP2, with Prescott that isn't microcode-updated to revision 8 or better, is not the ideal situation.  You really should update BIOS so that it updates the Prescott processor properly, for the definitive fix!

The problem of instability occurs with Windows XP SP2.

I suggest you to update to Windows XP SP3 to alleviate the problem as I see you use Windows XP SP2 as evident in your crash reports.

Any ideas as how to find out which drivers is incompatible with SP3 ?

The problem is greater than the sum of its parts. Remember, we have two kinds of memory: the one from system memory (SRAM cache) and the one resides on-die, part of CPU design (the L1 and L2 cache). Of course, the memory test can check both nowadays.

However, when it comes to microcode, this does not involve those types of memory. Now, we have another kind of memory: the registers. The registers are high-speed volatile memory inside CPU itself. These registers cannot be tested directly by any memory tester.

In Celeron and Pentium 4 Prescott which implements FC-PGA design, they lack "hard-wired" floating point unit (FPU). Due to this limitation, a microcode tries to compensate the lack of FPU by utilizing the available registers, namely arithmetic and logic unit (ALU) to emulate the FPU functions. The microcode is "downloaded" to the target hardware to give the necessary "software" functions. Microcode is common in writing a MCU or FPGA.

The zero-length microcode error can occur until the OS manages to find a "kludge" to fill the "hole" or "flaw" in CPU microcode. This is the solution made in most Linux distributions to patch the zero-length microcode error in Celeron and Pentium 4 Prescott.

QUOTE
Risks

Linux (on x86 PCs) has a patch program that fixes botched CPU microcode. Of all UNIX (and UNIX-like) operating systems on Intel (and Intel x86-compatible) PCs there has been an ongoing requirement to patch erroneous microcode since the FPU multiplier problem that was endemic to some Pentiums.

    * Microsoft Windows also has similar patches, but does generally not label them as such since Windows XP.
    * So far only x86 CPUs have microcode patches. This is unknown with RISC CPUs as well as general purpose DSPs

http://en.wikipedia.org/wiki/Microcode


Flaws in CPU microcode download can happen in small samples from number of CPUs in production.

If you are lucky, you should ask for a replacement CPU from Intel or blame Microsoft for not solving the problem completely, unlike Linux which its open-source programmers can patch the risk in the quickest amount of time.

Any user programs that use floating-point math will suffer the most when running on a CPU with no built-in FPU. In your case, you need to get a patch for your Warcraft 3 game that can solve the FPU issue.

Or, stop overclocking your CPU if you did just that.

may i ask wat is the problem??

If your hard disk is SATA type but your BIOS settings for hard disk mode says "AHCI mode", then it will display BSOD if you are using Windows XP SP2 CD since it does not have built-in SATA driver. It will try to install IDE driver, albeit the incompatibility (unless the "IDE mode" is chosen).

Even, the newer Windows SP3 CD may not have the built-in SATA driver support. Unless the OEM provides the custom made version with SATA support.

You need to choose F6 Setup mode to install the SATA driver for your chipset/motherboard from a floppy disk first in "AHCI mode".

SATA hard disk works better in "AHCI mode" only when the SATA kernel driver has been installed during the setup and that mode is selected.

But, it can run in "IDE mode" when that hard disk mode is used during setup. In this "IDE mode", it runs in "IDE emulation" speed with the default IDE driver.

If you are using Windows XP SP2 CD and you don't have a floppy disk, you can use nLite to create, customize and burn your own Windows XP CD with proper drivers. http://www.nliteos.com/

If you like the other way of doing this (for Intel systems), you can refer to http://www.tacktech.com/display.cfm?ttid=414
