Recently I built my first computer, not the highest end stuff but cerainly up there. It has a gtx 970, an i5 4590, and 8gb of ram. When I first started using it, I was getting a solid 60 fps on skyrim and Fallout NV maxed out, 1080p, with mods up the wazoo. But at somepoint, not really sure when, that performance dissappeared. Skyrim runs 30 fps same with Fallout 4 and NV despite me exceeding their recommended specs. I ran my antivirus, kapersky, to see if I had map ware or something, came out blank. Ran a program to test my CPU and ram for over 10 hours, and nothing. I'm pretty inexperienced with this kind of thing, so I don't really know how to troubleshoot this problem. Can somebody tell me what are the areas and possibly programs that I should be looking at in order to find my issue. Any bit helps, thank you.
