It seems to have quirks in handling older programs and YouTube. One, my Duke Nukem 3D game ported to Windows has hesitations like it has to pause and catch up on something. Two, if I pause the videos in YouTube it doesn't recover. It'll turn gray with artifacts and lock up. Plus there's other quirks I can't really explain. By the way, it's not OCed, I gave up on that. I'm thinking about putting my drive back in my i5-3570 and use it. At least it runs like a champ. Got any ideas? I just remembered, my sound can be screwed up sometimes. Now I'm wondering if it's the mobo that's funky.
