Re: BSOD
Hi,
Both new dumps attached are fatal hardware bugchecks: WHEA_UNCORRECTABLE_ERROR (124) and MACHINE_CHECK_EXCEPTION (9c). MACHINE_CHECK_EXCEPTION (9c) is entirely the same as *124, however, it occurs on older versions of Windows, as well as sometimes
very rarely on Windows 7 when the WHEA isn't fully initialized.
Unfortunately, with your 9c dump, we are unable to get any information from it for the following reason:
Concatenated Error Code:
--------------------------
There's no CEC.
STACK_COMMAND: kb
SYMBOL_NAME: ANALYSIS_INCONCLUSIVE
FOLLOWUP_NAME: MachineOwner
MODULE_NAME: Unknown_Module
IMAGE_NAME: Unknown_Image
DEBUG_FLR_IMAGE_TIMESTAMP: 0
FAILURE_BUCKET_ID: 0x9C_GenuineIntel_ANALYSIS_INCONCLUSIVE
BUCKET_ID: 0x9C_GenuineIntel_ANALYSIS_INCONCLUSIVE
There's no symbol, module nor image we can refer to to run a lmvm on to get more info.
Let's take a look at the *124 dump:

[COLOR=Red][U][B]Error : Internal timer (Proc 0 Bank 0)[/B][/U][/COLOR]
Status : 0xa200000084010400
As you can see, you have an internal timer issue on proc 0 bank 0. The CPU is possibly damaged, however I'd need to see a bit more *124 dumps to make that call for sure.
Other possibilities are overheating (please check temperatures and ensure they are within standard with any software of your choice), as well as outdated BIOS not complying with the rest of the drivers on the system.
Three things I can recommend for now:
1. Let the system keep crashing and attach ANY new dumps you get. Please do not attach old ones, only new ones.
2. Update your BIOS if possible (I know it may be hard if the system is really that unstable, and I actually wouldn't recommend this step at all if it actually IS that unstable). You can find the download for new BIOS versions on the manufacturers website. If you give me the make and model # of your system, I can find if it's available for you.
3. Unless the system is entirely unstable, you still need to update to Service Pack 1. This is of little relevance though now that we're seeing fatal hardware bugchecks.
