Im not sure if this have been ask about but i just got my new computer last friday and i have assembl it my self, then problem is this i get black screen after 10 min or less, its not only STO also in WOW.
But not in AVP3... i can play that fine i hours on hours.
3: if i can play AVP3 with no problems do you think its a Temp problem? i don't think so.
1. if you didn't OC it chances are its not OC'd
2. Not sure what program is used for OC with XFX but a quick google search would get you the answer and then you could download the program and OC or return it to default.
3. Actually its very possible that it could be a heating issue since STO could be taxing/demanding more from your GPU than AVP
A quick temporary solution you could try for temp issues is, if you have a small case with no or only 1 or two fans you could take the side panel of to cool the inside of the case. (only if the side panel has no fan on it though)
