BSOD constantly with same ntoskrnl.exe error and disk indicator is frozen

BSOD constantly and the disk indicator is frozen.
Error do not happen immediately, usually an hour after boot up.

Here is the Minidump:
Bug Check Code = 0x00000124
Caused By Driver = ntoskrnl.exe
Caused By Address = ntoskrnl.exe+4b094c
Crash Address = ntoskrnl.exe+4b094c

Seems to be hardware problem, but I checked RAM, no error.
I have two HDs installed, system is on SSD, data is on HDD.
Checked SSD with the properties->tools->error-checking , no error.
Re-installed several times, still happens even after removed HDD.

Configuration:

• SSD: Crucial M4-CT064M4SSD2 with Firmware 0009
• Intel HM65
• CPU: i7-2630QM
  

The SSD is set correctly, SATA III 6Gb/s enabled, and everything worked perfectly for nearly a year.

I checked system events, it seems caused by an error from WHEA-Logger
A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor ID: 0
The details view of this entry contains further information.

Cache Hierarchy Error, does this mean the CPU is broken?

This has a lot of options - too many to copy into the body but the accepted answer was:

AVG has been known to cause or aggravate these issues so I would uninstall it and run the AVG Removal Tool to prevent trouble causing remnants from being left behind. Below are recommendations to use while testing, even better permanently.

Here is what I use and recommend : (These are all Free versions and very effective.)

Avast and Prevx have proven extremely reliable and compatible with everything I have thrown at them. Microsoft Security Essentials and Prevx have also proven to be very reliable and compatible. Use MSE and Prevx or Avast and Prevx however not all 3.

Avast Home Free - stop any shields you do not need except leave Standard, Web, and Network running.

Prevx - Home - Free

Windows Firewall

Windows Defender (not needed if using MSE)

IE - Protected Mode

IE 8 - SmartScreen Filter ON (IE 7 Phishing Filter)

I also have IE to always start with InPrivate Filter active if IE 8. (You occasionally have to turn it temporarily off with the little Icon on LEFT of the + bottom right of IE)

Two versions of Avast are available 6.x and 4.8x

Avast 6.x - Home - Free - Stop the Shields you do not use (except File, Web, Network, & Behavior) - double click the Orange Icon in Notification Area - Real Time Shields - click the Shield you want to stop - STOP. To stop the Orange Icon from showing an error indicator - click the Orange Icon - Upper Right - Settings - click Status Bar - uncheck the Shields you disabled - click OK http://www.avast.com/free-antivirus-download

Avast 4.8x - Home - Free - stop any shields you do not need except leave Standard, Web, and Network running. (Double Click Blue icon - details next to OK. - upper left Shields - Terminate those you do not use.) http://www.avast.com/free-antivirus-download#tab4

Or use Microsoft Security Essentials - Free http://www.microsoft.com/Security_Essentials/

Prevx works well along side Avast or MSE

Prevx - Home - Free small, fast, exceptional CLOUD protection, works with other security programs. This is a scanner only, VERY EFFECTIVE, if it finds something come back here or use Google to see how to remove. http://www.prevx.com/ <-- information http://info.prevx.com/downloadcsi.asp <-- download

PCmag - Prevx - Editor'a Choice http://www.pcmag.com/article2/0,2817,2346862,00.asp

Also get Malwarebytes - free - use as scanner only. If you ever suspect malware, and that would be unsual with Avast and Prevx running except for an occasional low level cookie (no big deal), UPDATE it and then run it as a scanner. I have many scanners and they never find anything of note since I started using this setup.
