So I built this computer fairly recently. Before I had the graphics card ready to go, it all seemed fine, no crashes. Later when I had everything put in, I reinstalled Windows 8 and started to use it like normal. That's when these crashes started happening. Now I also use a DP10U tablet by yiynova from drawing. The crashes seemed to stop after I uninstalled the drivers. I got different drivers from the Yiynova site, and everything seemed fine for a few days until the crashes came back. I'd like to believe it's something else as i'd really like to keep using this tablet. But if it comes down to it I have a different tablet I can use. I've run a few passes in memtest but they haven't seemed to come up with any big issues. EDIT: Sorry, I forgot to put this in the Windows 8 forum!
