Tl;dr: Most games are crashing with a c0000005 exception. I have formatted discs, swapped out RAM and GPU but without any luck. Thinking of buying a new motherboard next. Thoughts?

I probably should have included some crash dumps, but I haven´t got my computer available at the moment.

NOTE: I have done memtest for several hours, ran stress test on CPU and GPU, disk check, watched temps and nothing out of the ordinary.

EDIT: I flashed my BIOS to the newest update some weeks ago. After that both GTA V and Farming Simulator 2015 worked for like 40 minutes total before the crashing started again.


Ever since i built my PC about 1.5 years ago, there has been some instability, especially with certain games. Most of my games are crashing with a memory_access_violation error and the error code is c0000005. Google Chrome tabs are also crashing, though not as frequent as my games. The only games I haven´t had any problems with are mainly blizzard games(they do however crash when running the 64-bit clients).League of legends, Trial fusion, Assassin's Creed IV: Black Flag and The Long Dark have not yet produced this crash either. I have had about 15 BSODs since I built the computer. Most of the BSODs has been ´irql_not_less_or_equal´ and has not occurred very often when running windows 7 professional. In windows 8.1 however , this would happen about 2 times a day. When I first installed windows 7 on my SSD it would not boot after install. I managed to solve this by reseating the cables to the SSD. I d

Not very long ago I installed some updates through MSI Live update, and i experienced some major instability. Windows explorer would continuously crash with the c0000005 exception and the same happened with svchost.exe. After that I formatted my system drive, but the crashes kept happening. I then removed my RAM(hyperx) and installed a RAM stick(corsair)which I borrowed from a friend. This seemed to take care of the explorer and svchost, crashes, but not the crashes happening when playing games. I swapped out the borrowed RAM with my own and this did not trigger the explorer and svchost crashes. In addition to testing with different RAM I also tested with a different GPU, but this didn´t fix the game crashes either.

Yesterday I got a BSOD, which I haven´t experienced in about two months. This time it was a machine_check_exception BSOD. From my testing, I have concluded that this is hardware related, as I have done clean install of windows several times, but without any luck . A new GPU and RAM has also been tested, but this didn´t solve the problem either. So my question is: which component is likely the culprit ? I am thinking the motherboard, but i wanted to see if I could get some input on the matter before buying a new one.

I appreciate all answers .

Yes, I did. I will try adding the extra volts now.

EDIT: Turning the voltage up did not seem to have any impact on the crashing.I also reseated my RAM and SATA cables. After 3 minutes in Farming Simulator 2015 I got a different application error.

This time I got two application errors: "Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program GIANTS Engine 6.0.2 because of this error." and another with exception code 0xc0000096.

After disabling DEP on my fresh windows install(tried disabling DEP on previous installs aswell) I got a BEX64 crash with the exception code c0000409.

EDIT: Added some crash logs to pastebin
The most recent crash log from GTA V

I currently have 3 fans installed in addition to the two radiator fans. All fans are produced by noctua. Some 6-7 months ago i tried to install a 4th fan in the bottom of my case. This did not work properly, as it would not start spinning by itself. Nothing wrong with the fan as I have been using it in another computer.

Could the PSU be causing the problems i´m having?

Running Prime 95 now:
I ran the Large FFT' test and I've gotten errors from workers 4 and 8. The error on worker 2 happened about 5-6 minutes after starting the test. The other happened at roughly 13 minutes. It runs at 4199.07Mhz(99.98x42) on 1.609 v. TurboBoost enabled.
Worker 4: FATAL ERROR: Rounding was 0.4988333088, expected less than 0.4 Hardware failure detected, consult stress.txt file.
Worker 5: FATAL ERROR: Rounding was 0.5, expected less than 0.4 Hardware failure detected, consult stress.txt file.
Maxtemp was 70 degrees celcius in core #2 The rest of the cores had a maxtemp of 65 degrees celcius.
Status: Running the small FFT now and im getting a max temp of 79 degrees celcius on core #2. The other cores from 74-76 degrees celcius.
I guess i'll be running memtest when I go to sleep tonight. I have tried different memory sticks, but the same gamecrashes kept happening.
EDIT: I've uploaded the crash report generated by BlueScreenView to my dropbox
