Computer BSOD on heavy loads


I recently got a new processor, an fx 8350 black edition, replacing a sempron x4, but when i try to run a cpu-intensive game (rome 2) or run stress testing such as prime95, it crashes out to blue screen.

There are a few different bsod memory dump messages that i haven't been able to make sense of, but they all point to ntoskrnl.exe issues.

It's not a heating issue, i ruled that out with a new cpu fan and i was watching temperatures on safefan anyway to see that it never really went above 50 degrees C. It also does not appear to be any of the other hardware, as i can put the sempron back in and this issue stops happening.

also while trying to resolve this i've reinstalled windows and downloaded everything fresh.

This link is to cpuZ's validation of my specs, and i noticed the cpu frequency was in red, could this be the problem? I'm not too experienced with changing those sorts of settings.

Does anyone have any ideas of what i can do to resolve this?


All drivers are recent and updated, here are some of the error codes:

0x00000101 - (no listed error)

0x1000007e - system_thread_exception_not_handled

0x0000000a - IRQL_not_less_or_equal

0x00000024 - ntfs_file_system

Whenever I see "IRQL_not_less_or_equal" it's usually RAM that's underpowered, especially if you are mixing different RAM modules that have different speeds. Increasing the voltage on them usually helps. Also, try running MemCheck86 ( to check if you have any bad modules. Note: undervolted RAM will throw errors during MemCheck (see picture: You should invest in a $15 power supply tester, and have that in your tool box.

Very rarely have I seen issues caused by bad cabling of the 4-pin CPU power cable.

If you have a second monitor attached, run HWMonitor ( and check the MAX voltages while your PC is reaching heavy load. If it's going over your CPU's recommended voltage, it might BSOD due to that (it's farfetched, but just throwing that idea out there).

BSODs can be caused by a lot of factors and you need to isolate that specific factor if you want to find what's wrong.

The first thing you want to do is a RAM test (at least 2 hours), then the second thing is a HDD test, block by block. If both your RAM and HDD are correct (assuming you are already with a fresh OS install), then you go with CPU test and GPU test.

The last components are the motherboard and the PSU. Really hard to test but if all the other components are good, you will need to find another motherboard and another power-supply to try it out.

Swapping the components one-by-one is another way to find out.

Remember that it is not always an exact science.
