Computer very slow.

I recently updated my computer to Windows 10, but this problem existed before the upgrade. Basically, when I start my computer it will get progressively louder and run slowly. My CPU usage is running consistently at 99%. When I go to check task manager, the thing using the most of my CPU is Windows host process (Rundll32). The thing is, I have 2 of those, they each run just under 50% of CPU usage. I have never heard someone talk about that before. If someone could help me out, that would be fantastic. My computer is a HP Pavillion P6000, 16 GB RAM, and AM Phenom II X2 511 Processor. If you need more info just ask, I'm not sure what to give exactly.

might be virus, could you check the rundlls with this software and see if theres anything suspicious? Process Explorer

Well, It may be a temporary fix, but I just ended the task for them both and my computer is working perfectly fine. Better than ever actually. Thanks for the help though!

Know what exactly you stopped running, did not mention it ?

Yeah I just went to task manager and ended the task for both of the Rundll32. My computer is running faster than ever and it doesn't sound like it's about to explode anymore.

Yes but as other member showed you to use the Process Explorer, you also need to identify the process using it, not just end it in task manager as will be a good chance will renable itself on reboot or eventually, look here http://www.howtogeek.com/howto/windo...is-it-running/
