Today, my laptop is still warmer/louder than usual and every now and then, a service host will hog 25% of my CPU and 59.3 MB of memory. I ran a MalwareBytes scan, which came back clean, so I uninstalled AVG (since I never use it anyway) and shut down for the night. AVG had been taking up about 5% disk usage and various Service Host: Local Systems were occasionally using ~25% CPU. Once it booted back up, I checked Task Manager for anything unusual. I had to press the power button to make it shut down. However, when it went to shut down, the screen was black but the power light stayed on and the fan was still running. I shut down the laptop to give it time to cool down. Yesterday I noticed that my laptop had been warmer than usual and the fan's noise was more noticeable than usual. I did notice that there were two new notification icons in the lower right-hand area of my taskbar: the little Windows action centre flag with a red X, and AVG's icon, also with a red X. On Monday when I booted up my laptop (Samsung using Windows 8), I suddenly had a BSOD due to an error called "PAGE_FAULT_IN_NONPAGED_AREA." As soon as my computer restarted, it was fine. My laptop has been acting a little funny recently and I'm wondering why.
