New Build Unstable

[Nezime]

I recieved the parts to my new build on friday and got it running, and ran Memtest and Seatools and things were going fine. Got OS installed and ran Orthos to check for stability, after 5 hours one instance failed out. I haven't messed with anything yet and temperature under load never went above 53 degrees. Does anyone have any suggestions to make it more stable?

Had been adding system specs when you posted but you were too fast for me. :p By unstable I mean while running Orthos after 5 hrs it reports a fatal error.

Are you running the game at max settings? If so try running at normal settings.. Did you OC this set up? if so go back to default settings and see what happens. Do yo have all the latest updated drivers?

I had stability issues as well with all tests coming back normal.
I took out 2 GB from the 4 GB that I had and the computer is running fine now.

Try that.
