It is sounding more and more like it. Hopefully running the above will help determine what is causing the error either the graphics or CPU (unless it goes black with both of course).
Best of luck anyway.
Ok well thanks for trying at least.
The one thing we do know is that the error seems to be generated on the CPU side of things as opposed to graphics.
Ideally it would be really handy to test each component in a different machine. Do you have a friend who would help perhaps or do you have enough parts lying around to cobble together a test system? Either way you could then test the cpu and see if it does the same thing. If it doesn't then it's probably to do with the motherboard but until you start testing it's hard to say for sure.
I’m certainly no expert and I know you guys have put a lot of hard work and effort into chasing down this problem, but……..
From your very first post.
I checked my CPU it has black lines.. See images.
I tried to rub it with cloth and it was getting off, is that dust? Will that effect? If yes, then how can I clean it in a better way? Is this CPU is issue?
Do you have any idea or explanation as to how that corrosion may have come to be?
While the pictures you included are not of the best quality it looks to me like something either got very, very hot, or you may have had a leak from a possible liquid cooler, or else some thermal paste has somehow found its’ way down into the ZIF socket.
In any event I would take it very seriously and make every effort to completely eliminate it both from the processor pins as well as the socket itself.
As to how to actually accomplish that…. It would probably be dictated by what it is and how it came to be there in the first place. I would try some compressed air and maybe a very delicate / soft brush of some type.
From post #16
It looks to me a hardware issue, as when I was in safe mode, and I tried compressing some file using winrar and winzip I got black screen.
Did you do anything different from the last time we posted?
What about Troubles observations?
Did you act on his advice at all?
To me the CPU looks like it's been getting hot or it's been marked from some electrical discharge or it could simply be, as suggested by Randy, some thermal paste that's gotten into the socket. I tried looking through google to see if I could find an image which matched yours but no. On checking photo's relating to electrical discharge the marks looked different which is why I held back on passing comment.
It could be that whatever was troubling the CPU has burnt off but keep monitoring the situation and post back if need be.
I have send my processor and motherboard for RMA and got it back now.
AMD send me a new processor.
But ASUS repaired the mobo and send me back.
After using it, I am again getting black screen on load work.
Also, I have noticed one thing..
I got the black screen after using my computer for few hours.
Means I was working on same thing which I was doing last night after using my PC for 7-8 hours and getting black screen.
I was playing throne rush on fb with 4 more pin tabs open in google chrome and got black screen.
Today in morning, I have done same thing and no black screen.
What can be the reason?
Or maybe some other component failing after using for few hours?
As temp can;t be the issue, as I have CM trooper cabinet with 8 fans installed, including 1 200mm on top and 140mm on back and other 120mm.
