I'm not sure if I am infected or not but I have had this laptop for almost a year now, and also had the motherboard replaced. Ever since I received the new motherboard I feel like the laptop has been decreasing in speed more and more everyday. Some issues I have is when I watch videos or play games installed, or even listening to music, the computer slows down for a few seconds and the audio slows down, sounding really demonic. Same with the video. It happens about once every 2-3 minutes depending on what I am doing. My laptop also gets very hot so I bought a cooling pad but that didn't really seem to help. I scanned the computer with Malwarebytes and Avast. Nothing came up. I also installed a program that optimizes and cleans the computer. Seem to help a little bit, but not too much.
Dell XPS 17 L702x
Intel Core i7-2670QM CPU @ 2.20 GHz
8 GB Ram
Windows 7 64 Bit
Any help is appreciated. Thanks!
