Hi there. I'll try my best to explain my issue, so please bear with me!
I've had my laptop for a good few years now, since about 2015, with almost no major issues. Recently, though, when I start up my computer, I've noticed heavy lag and stuttering in my audio and video freezing up when watching videos. When I open Task Manager, the CPU shows itself to be at 100% usage for a split second before shooting down to 10%. Close Task Manager, problems start back up, rinse and repeat. Occasionally, my laptop freezes completely and become non responsive as well. I've been unable to locate any viruses manually, and a Malwarebytes scan pulled up nothing an I can't seem to find the root of it on my own.
I have done a scan with FRST and have attached the logs below. Would appreciate any help given! Thanks
