Hey guys, I've been experiencing this weird problem with my computer recently and I was hoping someone here might be able to help For the most part it works fine, but every 6 minutes or so the screen will flash black for like one frame and then it'll lag. This happens for any game I play, and it takes different forms. When it happens in Saint's Row the Third it feels like I'm playing in slow motion. In online games, it just feels like extreme lag. It even happens on small games like Terraria and Minecraft, although those don't lag, they just flash black. The lag usually lasts for a minute or two, but then it flashes black again and it works perfectly fine. I'm using an Nvidia Geforce GT 330M. I've tried updating the drivers, and that worked for about an hour but then it started happening again. If anyone knows what's going on I'd appreciate some help, it's making a lot of games unplayable.
