I would like to introduce you an issue that im having right now with my PC. It's an AMD FX 8120, 8GB DDR3, Asus M5A97 PRO, AMD RADEON 6970 and a CollerMaster Extreme Power Plus 600w. Until a few days, my pc was doing good with games, videos and the routine activity of a web developer. My games (Diablo 3, BF3, NFS:MS2, Tribes Ascend, TERA and a lot of indies) were properly played, smoothly at full resolutions. I do recognize that my CPU Case doesn't have an optimal cooling setup, but I didn't let the temps shut down my CPU. I mean, I saw temps at 75 average, but I don't know what the problem was. Anyways, even with those temperatures, my games were played smoothly and without problems (besides my lack of aim or/and luck). Suddenly, before a restart, my games started to feel stuttered. And with that, i mean this (http://www.xfire.com/video/77b92 Video is not mine, it just an example.) The issue is not only present when I play full hd 3D games, but also in some HTML5 games and flash that needs some gpu power.
I tried removing drivers and updating and downgrading, re installed windows, cleaned my pc case (it was pretty much clean, thou), my power supply was ok when I opened up. CPU, GPU, MOBO and their respective coolers and sinks were ok. I checked latency and i have normal values, i have put an small home fan and temps dropped 15º C but still had the same problems.
I have everything to check and im keen to do everything you advice for the sake of my gaming life. I have no money to buy another PC or to replace any component to test it out. So i hope this is just a matter of configuration and stuff.
to move things forward, i'll attach some information about my pc and some test done to it.
Thanks in advance,
