Vista - Please help with BSOD STOP 0x00000124

Hey everyone,

I've been having lots of random blue screens recently all with 0x00000124 codes (see attached screenshot) on Vista64 Home Premium.

My PC isn't overclocked. Just deafult settings in the bios.

All BSODs seem to be random. I can go days without one but I've had 3 already today (see attached dmp files). It seems to happen when I'm clicking with the mouse (Wacom pen) but I also have tried other mice and still get the BSODs.

It's driving me nuts. I'm not a huge techie so if anyone can offer advice I'd really appreciate it.

Thanks
John

Hi Artzone, restart your computer in safe mode with networking. If it boots up, update the BIOS from the motherboard manufacturer's website.

Look here it might have your answer:

Stop 0x00000124

Unfortunately, a stop 0x124 is a hardware error report being passed along by Windows. I wrote up some info earlier on how to dig up more information out of the hardware error report, but it's not a particularly simple thing to:

Blue Screen twice - Any ideas why?

@avgwarhawk Thanks, I've tried the suggestions you linked to but still getting the bluse screens.

@kavita I'm already using the latest bios from Asus

@H2SO4 Thanks, I've had a look at your article but it goes completely over my head. Is there any info I could post that could help identify the problem?

Already 2 more BSODs today and it isn't even lunchtime. Maybe it's time to buy a Mac

Seriously though, is this likely to be a fixable problem or is it time for a new machine?

A stop 0x124 is fundamentally different from other types of bluescreens because the "we must crash now" trigger is the hardware, not software. The OS passes on the hardware error report as a "stop 0x124" because it can't do anything else once the hardware has signalled an uncorrectable error condition. It's theoretically possible for drivers to indirectly cause hardware to trigger MCEs by "driving" in ways that are confusing to the hardware, but from the point of view of a home user that disctinction is so subtle as to be irrelevant.

It's important to note that there are literally squillions of different possible causes for that hardware error report (it's called a "Machine Check Exception" - MCE), and one person's stop 0x124 is likely to be entirely different to another's. Hence, posts which begin with "I had that error too, and then I reconnected the mini-molex on my FDD to fix it..." are almost always misguided because they're random stabs in the dark which are statistically highly unlikely to help anyone else experiencing MCEs.

It's relatively simple (but painful) to interpret the hardware's error report. It's in the so-called MCi_Status register, the contents of which are actually visible as bugcheck parameters 3 and 4 in that photo of your screen, as well as each of your minidumps. Interpreting the numbers is just a matter of consulting information published by Intel and AMD. (I've done it below based on your first minidump. This is such a common request that I might code a little utility to automate the process.)

The trouble is that the hardware's complaints are never "practical", in the sense that they would tell you what's wrong in layman's terms and include a recommendation for how to fix it. Instead, it's esoteric stuff which only tends to make sense to hardware folks and driver developers. Hence, a basic "0x124 home user troubleshooting strategy" might look something like this:

0) If it's under warranty, take it back to the shop. The hardware is reporting errors and you don't want to run the risk of troubleshooting it yourself with an uncertain outcome - you just want a machine that doesn't report MCE errors. Otherwise...

1) If overclocking, don't. Hardware that is driven beyond its design specs - by overclocking - can malfunction in weird ways.

2) Open up the side of the case and point a mains fan into the guts of the PC to rule out most (lack of) cooling issues.

3) Update all hardware-related drivers: video, sound, RAID (if any), NIC... anything that interacts with a piece of hardware. This is a desparation step, but it's legit once you're faced with having to rip out and replace bits of the machine, plus it's generally good practice to run the latest drivers anyway.

4) From time to time the OS drivers themselves may be contributing to an MCE. The scenarios are very specific and very rare, but try applying the relevant updates anyway. For example:

http://support.microsoft.com/kb/956115

5) Clean and de-dust the inside of the machine. Reseat all connectors and memory modules. Use a can of compressed air to clean out the RAM DIMM connectors as much as possible.

6) If all else fails, start ripping out bits of hardware one-by-one until a culprit is found. Obviously, this is a lot easier if you've got equivalent hardware lying around to perform swaps.

=========================

The MCE info in the first of the minidumps you've posted suggests a bus parity error is being reported:

Thanks for the reply. I really appreciate you taking the time to answer.

Ok, I've tried all your suggestions and I've even tried a fresh install of vista 64. I thought it had worked but after a couple of hours, I got the same bsod

I've run memtest on the ram and there are no errors. I guess the next step is to start replacing bits. I'm considering replacing the motherboard and CPU at the same time. Not sure of that's a sensible thing to do but it's either that or trash the whole thing and start again.

Hi Artzone

If you go into the bios and set everything to auto/default then download and take screenshot of HWmonitor and the first tab of CPU-Z when it boots. That will help in being able to identify any problems

Hi Stew2,

Thanks for the info.

Screenshots attached...

Mmmmm nothing looks wrong there which means your going to have to find the hardware thats causing this.

Switch off your pc and then opn the side panel and unplug from the motherboard your dvd drives etc. Take out all but 1 stick of ram. Take out any pci cards you have as well

So your left with the motherboard, the cpu, 1 stick of ram, your cooling fans, the hard drive and the powersupply then start your pc and see if it works without getting a BSOD.

If it does then try it with both your sticks of ram. Next install your pci devices and boot up and see if its useable without getting BSOD. Then install your dvd drives etc and see if the problem exists with them installed. The last component that you should install is your graphics card.

Try and run each senario for as long as possible to test the components installed.
