I have a intel i5 2430m CPU, and after I watch a stream for a while or play a game, CPU 0 goes up to 100% usage. It persists at close to 100% at all times until I reboot my system. I've been loosing myself in your threads for hours upon hours now, trying to get everything to work and this is what I've come up with so far! When I try to use the "xperf -d latency.etl" command or "xperf -d DPC_Interrupt.etl" I get a message saying that events were lost and that I need to increase buffer. I really can't make sense of it anymore, I'm jumping back and forth between your threads trying to decide what problem I'm actually having. However I got the Latency Monitor to work and I compiled screenshots + the log from the test it ran there. I'm really sorry if I'm posting in the wrong thread/not showing the needed info, I just felt like I needed to get something out here Latency monitor.rar
