Hey! I hope someone here will be able to help me. I am on Windows 10 Professional x64. Within the past week, Task Manager has started reporting that I am using 100% CPU on my Core i7 950 (3.07GHz quad core). The thing is, none of the processes are very high in usage... They definitely do not add to 100%, and the graph never dips, even a little bit.
It must be an program that does not work well with Windows 10 that you have running in a background. I would say is that create a System Backup first so you can revert to back to this state. Then start uninstalling programs that is not required by Windows which I see a fair amount of.
I'm starting to think that Windows is seeing the CPU usage as a relative usage rather than total. i.e. the percentages shown would signify how much that process is using of the current CPU usage rather than the total CPU capability. Then Task Manager shows the CPU usage as 100% because the current CPU usage has refers to itself... I hope that makes sense.
The reason I think this is what is happening is because I started killing processes and I noticed that processes which usually only took 1% or 2% of the CPU started jumping up to around 50% or 60%. The amount of CPU usage they are using in relation to the total amount of CPU being used is higher now that the larger processes which took more CPU are killed.
Okay, I am going to run these scans and then I'll probably start uninstalling some of my recent software. I know this was not happening more than a week ago, but I'll go back like a month just in case. Thanks guys :)
If that doesn't work. Reset the PC back to factory settings aka just Windows nothing else and it should work. Then have the most epic time to install the programs that you need.
I know. I had to reinstall Windows 10 itself 2 months ago because my SSD kicked the bucket. I was previously running on Windows 10 before that. Honestly I'd love to go w/ Linux but I'm too dependent on the Microsoft, Adobe, AutoDesk, and other programs that only run on Windows. Plus most of my games.
I see that your google chrome uses a rediculous amount of cpu. That looks a bit suspicious to me. I would say install a decent viruscanner, and malwarebytes, and do some scans first.
And thinking about it now, I believe the reason this started was because I had heard a high pitched sound coming from my CPU a while ago; I decided to try and figure out how to make it stop, and came across these instructions: (From http://www.tomshardware.com/forum/292915-30-high-pitched-noise-coming-area)
I followed the instructions, and the sound did stop. I'm thinking this must have made the System Idle Process appear in the task manager though, which would make sense I guess.
