BSOD 124 and random hangs up during idle

[deeper33]

Hi, I've experienced BSOD 124 for a week or two now. I'm blind to which cause is to be suspected. As I am an ordinary user, I would like to get some help from the pros. Thank you in advance.

p.s. today BSOD 50 came up and it tried to search for some unknown driver

· OS Windows 7
· x64
· Windows 7
· full retail version Windows 7 Ultimate
· 4 years
· OS re-installed to solve BSOD, instead of solving BSOD, brought with it random hangs up

· Intel (R) Core (TM) 2 Duo CPU T6600 @2.20 GHz 2.19 GHz
· ATI Mobility Radeon HD 4500 Series
· MotherBoard - (you mean) INSYDE 1.50 ??


· System Manufacturer - TOSHIBA
· Exact model number (if laptop, check label on bottom) - Satellite L510 -PSLFLL-009001

Yes, thanks!

Many of the attached DMP files are of the WHEA_UNCORRECTABLE_ERROR (124) bugcheck.

A fatal hardware error has occurred. This fatal error displays data from the Windows Hardware Error Architecture (WHEA).

If we run an !errrec on the 2nd parameter of the bugcheck (address of the WER structure) we get the following:

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

  Status      : 0xb200004000000800

BUSL0_SRC_ERR_M_NOTIMEOUT_ERR = Implies that the processor sent out a read request to L0 Cache, and there was a delay in return (cache miss or corrupt / invalid data in the cache).

The majority are of this error, however I saw a different one as well:

There is only so much you can do with a bugcheck like this until it comes down to a faulty processor that will need to be replaced. Start from 1 and work downward:

1. Ensure your temperatures are within standard and nothing's overheating. You can use a program such as Speccy if you'd like to monitor temps - Speccy - System Information - Free Download

2. Clear your CMOS (or load optimized BIOS defaults) to ensure there's no improper BIOS setting - How To Clear CMOS (Reset BIOS)

3. Ensure your BIOS is up to date.

4. The only software conflict that can usually cause *124 bugchecks are OS to BIOS utilities from manufacturer's like Asus' AI Suite. If you have something like this software-wise, remove it ASAP.

5. If all of the above fail, the only left to do is replace your processor as it is faulty.
