Hello!

I have some crazy problem.... When my pc is in idle the the computer freezes and the picture turns either black, yellow, grey or red (the sound for example while watching movies stops but all the fans etc are on like they should)

There is no error code on the motherboard (Asus maximus hero Vii) and no red lamp lit on the mobo or anything when it happens, and there is no error code when I restart it by the restart button or error message on start up.

I just restart the pc with the button and It works like normal until it happens again (like 2-4) times a day under a couple of hours of use.


I recently changer my ram from 2 set of different corsair (2x4xms3 and 2x4 vengence with same specks 1600mhz xmp cl 9, and they worked like a charm for a long time) to 2x8 hyperx savage 2400mhz cl 11, i ran these at xmp profile 2 in 2133 because my pc refused to boot with xmp profile 1 2400mhz. (tryied the xmp profile 2400mhz at stock Cpu and with 4.4 oc and
It didn't matter it won't start at 2400mhz so I settled for 2133mhz.

I also changed my gpu at the same time from r9 290 tri x to a gtx Msi 980

Right now Im running the Cpu at 4.4 at 1.198 vcore as I did before the ram and gpu upgrade and it has worked perfectly for a long time (this was before the ram and gpu upgrade). I've run alot of realbench bench tests and no crashes or lock ups or anything and my temps are never over 70 while benching (I've never let the temp go over 82 while trying to push it to 4.6)

So can it be my ram who is faulty or is it my gpu or gpu driver's (the most recent) or is it my Motherboard or ram slots?

It always happens under idle (away from pc) or while watching movies never when I play witcher 3 even tough a session can be like 3 hours, cpu temp while gaming is like 67 at the hotest core.

I have power option at high performance and Ive done so nothing is going to turn it self of not the screen, hard drive anything and the system is set to not go in to sleep mode or anything like that even thing is turned of and att max performance.

As I write this I've disabled xmp to see if the problem is going away when I run the rams at 1600 mhz stock.

I hope it's not my gpu as I bought it used and with no warranty...

So help me pleas to figure this out I personally think it's the ram but I really don't know... I'm gone run som memtesting to night or tomorrow.

I have tried some immense oc'ing with alot of volt changes to alot of things etc etc but for now it's just multiplier and vcore that is changed if it goes on I will reset bios and se if that helps.

Really hope someone can enlighten me on this!

Kindest regards John
