Hi there. This is my first time posting onto this website. I ran into a problem last night after I restarted my computer, where any game that I start or even slightly intensive program I open, my CPU usage raises from ~14% to ~100% instantly. I have tried this on many programs such as Minecraft, any games on Steam, Firefall, and even some of Malwarebytes when I was scanning if a virus was causing this. None of my anti-virus software detected a virus, so I'm suspicious as to what the problem may be. Here are my computer specs:
Processor: Intel® Core i5-3550 CPU @ 3.30GHz (4 CPUs), ~3.3GHz
Graphics Card: NVIDIA GeForce 8800 GT
Memory: 8192MB RAM
OS: Windows 7
Request any extra info if needed. Thanks.
