Hi, I'm new here so hope I'm not breaking any forum rules while asking for help here. This my problem: I'm pretty proud of my laptop as it runs smoothly as compared to most of my friends' computers. However recently my computer start having CPU spikes (where CPU starts working for no apparent reason) and thus cause "sticky mouse cursor" (cursor not moving smoothly). The problem is much more obvious while I'm playing game online (Specifically, DotA) with my friends. While it ran smoothly in the past, it now has occasional lag spikes and even freezes when there are many items in one screen. I've ran through Howard's "Viruses/Spyware/Malware, preliminary removal instructions", having done Steps 1 to 11 (I skipped step 10, the tools look intimidating), turns out clean so far. Thus, please help check through the Hijackthis log and search for my problem, thanks. I'm beginning to wonder whether it's the processor hardware problem. Edit: The lag spikes sometimes come with sound distortion.
