MB:Asrock 970 pro r2.0
CPU:FX-8350 @4.0ghz
RAM:4x2gb DDR3 1333mhz Corsair XMS series
GPU:GTX1060
PSU:Corsair CX600M 600w 80+ Bronze
HDD:1x Seagate 2TB 1x Samsung 500gb

Hey guys I've had a problem with my system where it blue screens and shuts down/restarts randomly, sometimes even freezing completely during games. I had the MB replaced but still, it blue screens and freezes. The repair shop I took to who originally fitted the board advised maybe the CPU is at fault, I am taking it back tomorrow for another test.

Stressing the system I noticed on prime95 blend it quickly shows cores failing with normal temps but I tweeked some bios settings and I've tested for 3 hours twice, no errors. Currently 5 hours into an 8 hour test, no errors so far. However, the system still blue screens most days, usually during games or an hour or two afterwards. My GPU also bugged and was stuck at pcie x1 and giving terrible FPS until I reseated it thought not sure if this is related? Getting some pixels and artifacts on the screen for some video playback too but its rare.

Do you think my CPU is faulty like the technician has said? I've heard its extremely unlikely. They have also said RAM, PSU and HDD were okay but I really don't know. My gut instinct is that its not the CPU because no errors on prime95.

Any feedback much appreciated, cheers.

Reverting to default and running prime 95/OCCT I get errors within seconds. When I set my OC settings to manual and set it to stock speed it seems stable on prime95. I got it to run for 6 hours no errors. Then a couple hours later it blue screened when I was watching a yt video.

It's possible that it's a faulty CPU. What are the blue screen error codes? Usually those can point to an issue with specific hardware

The most recent was ''ATTEMPED EXECUTE OF NO EXECUTE MEMORY'' and it is often ''IRQL LESS THAN EQUAL'' all point to ntoskrnl.exe. I can probably upload the .dmps if you need them.

Do a clean uninstall of all of your drivers using some kind of software, and reinstall them. Attempted Execute of Noexecute Memory is a driver issue.

Update: Coming back from repair they told me it was fine after a windows reinstall. Looks like it was a software issue, some other interesting details though.

As soon as brought it home and plugged it in, it bluescreened immediately. Then the pcie went back to x1 instead of x16, had to reseat it like last time. I asked the repair shop if they had any problems like this when they were testing and they said nope.

I am about 95% certain the causes for the crashes is TV I use. I noticed refresh glitches before bluescreens. I also had a similar issue with bluescreens on my old PC which used the same TV. I am fairly certain that the TV is somehow corrupting drivers and causing crashes. The TV has been faulty for a while showing an extremely grainy/pixelated picture for 10 minutes when I turn it on then it will subside one row at a time (best description: it looks like someone hit the screen and broke it but then it subsides).

My plan right now it to buy a new HDMI cable and see if that's the problem though I have strong suspicion its the TV itself in which case I will buy a new monitor. Don't have anything else to test it on really. I know it seems terribly unlikely but this TV is very unpredictable to say the lest. I think it may have even crashed my xbox360 a few years back, I always put it down to overheating.

Ill post again the results once I have a new monitor up and running.
