Hi Guys, I have also the same problem of black screen then PC rebooting.
I just recently changed my MB and CPU, and the rest of my hardware i tranferred (GPU, RAM, DVD burners, HDD). This is what I’m running:
Asus Z87-k
i7 4770
Ati Radeon HD 5670
8 Gb Ram @ 1333
I can play for 5 hrs and then boom it shuts down… CPU is not overheating ( max 62 degrees cel.) , GPU max was 56, MB was 28. So no overheating there. I thought the cause was the PSU so i changed it….still reboots….so its not the GPU nor the CPU nor the PSU…Checked Ram with Memtest…no errors found…. Updated all drivers, even the BIOS! Still it reboots!
Is there something I’m overlooking?
Could it be a defective MB? or simply GW2 doing all of this?
Thanks for your help!!!
