Random idle BSOD 0x124 @ ntoskrnl.exe. ~Once / day

Today the errors started appearing in rapid succession (around7 times). Added new zip file with more info

Anyone? Seems like they cannot help me at the store, as it is not obviously broken :/

I cant believe my problem is so much worse than all the other posts here that nobody is replying!

Just exhausted my last 2 options I could think of:

- Overvolting the CPU (VCORE) by +50mv from the BIOS
- Disabling USB 3.0 ports all together in the BIOS

Anyone?

Anyone?

Code:

BugCheck 124, {0, fffffa8005000028, be200000, 2110a}

Probably caused by : GenuineIntel

Please reset the BIOS settings back to their default values - How To Clear CMOS (Reset BIOS)

• Hardware - Stress Test With Prime95

Enable "Round off checking" before the test (see first post below tutorial).

• 
  Stop 0x124 - what it means and what to try

All the hardware seeming to be running stable and tests reporting no errors, could mean a bad motherboard.

Thank you for your reply.

Are you sure that all the hardware is running stable? From the report you posted I read this:

Error : GCACHEL2_ERR_ERR (Proc 3 Bank 7)

Could that not mean that the CPU is bad? Considering the L2 cache has invalid values with specific bank numbers?

I already tried resetting the BIOS (both with jumper as 'soft reset' factory defaults from the menu. BSODs keep happening.

Also, I have run both Memtest and Prime95 stresstests before as indicated by the link you posted. These show no abnormalities. This is in line with the fact that the BSODs are not seemingly linked to system usage / stress but also happen randomly.
