The first thing i did was to run DPC Latency Checker. It reported very high DPC, so i started researching on the net, and found this thread on your forums: https://www.sysnative.com/forums/windows-7-|-windows-vista-tutorials/5721-how-diagnose-fix-high-dpc-latency-issues-wpa-windows-windows-vista-7-8-a.html After reading it, i installed LatencyMonitor to find out more details about what is causing the problems. I have attached a couple of screenshots from LatencyMonitor from when i play a 3d game. (Dota2). I also ran a test with a less graphics heavy game (Magic 2014), and i can included those screens if needed. I've tried following some of your suggestions, and so far i have updated my Network and Audio drivers (Realtek). I have also updated my USB3.0 Drivers, but im currently using 2.0 ports. Here are my computer specs: CPU: Intel i7 930 (2.8ghz, Bloomfield) RAM: Corsair 2x4GB DDR3 1066 Mhz Motherboard: Gigabyte GA-X58A-UD3R (rev. 1.0) GIGABYTE - Motherboard - Socket 1366 - GA-X58A-UD3R (rev. 1.0) HDDS: 2 Samsung Spinpoint 1TB (SATA) + an older Maxtor 250gb HD (IDE) (for my MP3 collection only). GFX: Sapphire HD7790 SAPPHIRE HD 7790 1GB GDDR5 I've also tried varius other things, like increasing my Page File and fiddling with Microsoft Security Essentials. I really hope someone out there is able to identity my problem and hopefully help me get rid of it. Thanks for reading.
