reboot's when heavy gaming

[aaac2594]

Hi everyone!

i recently bught a new MSI Gaming 4g gtx 970, when playing batman arkahm knigt i have easy 60 fps, but when i changed the resolution to 1440p, after 20 minutes mi pc sudenly reboots itself.

i changed the included 6 to 8 pin adapter to an 8 pin conector from mi 660wts power suply, and now i got anoter reboot when changing the resolution to 1440p, this time with witcher 3

any idea? i can change the gpu using the garantee, but i'm not sure if is the gpu what's causing the reboots

testing now with the cpu overclock disabled, could be a cpu overheat

what was your previous gpu and did you have any issues with that?

asus gtx 660ti, any truble, without the cpu overclock, witcher 3 caches after 40 minutes, in after burner everithing seems right, i will deecrease 20mhz to my overclook

 

sorry for my english  thnx for the help

Best place to start is turn ALL overclocks off as that is the number 1 or 2 issue.

at factory clocks i have no issue, but y stress test my gpu 2 hours

 

maybe the temp of the gpu under load is heating up my cpu, i have aircooling in both cpu and gpu

i disconected everything from the wall, my house is really old, maybe is power related? 

reboot's just when i change the resolution to 1440p

same again, this time with battlefield 4, just when changing to 1440p but not when increasing resolution porcentage
