After I upgraded my video card to a Geforce 660 TI I noticed that after a couple of minutes in, my CPU gets an additional 50% on it. I'm very afraid that if I dont do something about this it will greatly shorten my CPU's lifespan. I've done everything I could. Checked my PC with avast and malwarebytes, I'm clean. I've noticed that svchost has been taking a large amount of CPU, in particular 2 Services: PlugnPlay AudioEndPointBuilder I know that those two processes are key Windows related ones and cancelling them will just ruin everything all together. Anyone got any ideas on how I can solve this? Pre the hardware updates my CPU was just fine, going up at 2ish% while idle, now it's 50ish.
