Hello all :)

Just build this pc and I am constantly getting BSOD, usually happens while playing Diablo, haven't seen it happen so far while outside of diablo

· OS - Windows 8.1, kept HD from old build which was working fine so I doubt its the OS
· x86 (32-bit) or x64 ?64 bit
· Age of system (hardware) Everything is about 1y or newer
· CPU i7 4770k
· Video Card GTX 760
· MotherBoard MS-7845
· Power Supply - brand & wattage Corsair TX750

· Laptop or Desktop? Desktop
 
A couple things to remember when building a new PC. 1. a new build with new mobo/cpu requires a clean install of the OS. 2. Hardware components must be checked and rechecked for proper installation/firmly seated. 3. That all the cable connections to the hardware components and mobo are in the correct places and firmly seated.

I see no mention of your RAM? How many sticks and how is it populated...it does make a difference?
 
Running x4 4G on my MOBO, so using all 4/4 ram slots. I checked that all hardware was firmly seated a few times along with the cabling. Will try to run some stress test on my GPU/RAM/CPU and see if any of them are getting some errors.
 
Hi,

All of the attached DMP files are of the WHEA_UNCORRECTABLE_ERROR (124)

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 bug check (address of the WER structure) we get the following:

Code: 
===============================================================================

In your case, we're dealing with a Translation lookaside-buffer (TLB) error. It specifically occurred on Processor #4 and Cache Bank #2.

What is a TLB? In a very basic definition, a Translation lookaside-buffer (TLB) is a cache that memory management hardware uses to improve virtual address translation speed. All current desktop, laptop, and server processors include one or more TLBs in the memory management hardware, and it is nearly always present in any hardware that utilizes paged or segmented virtual memory.

By default, a TLB miss whether caused by hardware and/or software complications is not fatal (if the virtual address is not stored in the TLB, it's simply computed and found manually from other source data), but we're crashing on a TLB failure, this implies that the CPU determined there was corruption or a hardware error in date, therefore notified Windows that an unrecoverable hardware error has occurred.


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. Software conflicts 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 you unfortunately seemed to have gotten a dud CPU.

Regards,

Patrick
