Hey All,

I am running out of idea's here. Any help would be appreciated. I did a new Z390 build (everything new, except the GPU) and everything was working perfectly for the first week or two. Then minor crashing started with some applications. Didn't think much of it until it became common. All graphics drivers and Windows 10 are up to date. It was to the point where I would open of a webpage, command prompt, or ...anything at all, and the program would close. The desktop started to have graphical errors and taring and started to get BSOD for everything from System Exceptions to the Nvida BSOD error. I clean installed Windows 10 on a freshly formatted drive, though same issues. It is now to the point were I cannot even boot off a USB Windows 10 UBS drive without getting a BSOD. The computer POSTs just fine.

Current Setup (all new, except GPU):

Gigabyte Z390 Aorus Ultra
i5-9600K
EVGA Supernova 750 G3
Corsair Vengeance LPX 16GB (2X8GB)
860EVO 1TB
Nvidia 770 GTX


Testing so far:

Replaced Nvidia GTX 770 with older 570 (known good) card. Then removed card and used the on-board graphics. No improvement found.

Swapped SSD's with known good SSD from last build (Windows 7) and still had BSOD.

Removed each memory module to see if problem persists. No improvement. Ran Memtest86 on both, then each module. All cases had errors on Test 6. This doesn't make sense to me and I question if these are false positives, given some other experience people have been having. Being these are both brand new, the chances of both failing after a week of operation seems very slim to me. Perhaps I am wrong?? I may need to follow up with Corsair regarding this.

Looking at the BIOS, the CPU temps are low. There has not been any overclocking done to any components. I have updated the BIOS to the latest (after the problems started) and this did not help.

I am running out of ideas, at least without swapping parts. I am left with the Motherboard, PSU, CPU, or perhaps the memory. Has anyone else experienced this?

Kind Regards,

Brandon


Update:

Swapped out memory and reset CMOS. No improvement found (actually got worse. Could not even finish Memtest86 due to too many errors). Narrowed down to either the CPU or the motherboard.

Update 01/23/19:

i5-9600K is the culprit. New one is installed and running. Hope this isn't a larger issue with the 9th Gen CPU's. What a pain to diagnosis.
