So I've had win10 since release, and nothing ever even took more than like 5% cpu, and today spotify is using 30%, firefox is jumping around 15 to 30%, my games are taking around 40%.
I havent seen any new windows updates, was anything changed to cause this or what could cause this? The only thing I downloaded lately was a nvidia update but I don't know if that could cause this.
Best to list system specs, either fill them in here.Knowing this can help us. Regularly closer to 100% would be considered high,
then would be an indication that there is something going on in the background that is consuming too much processing power, the background activity may be produced by a virus or malware, by hardware specs being too low for the resource-heavy software the user is trying to run. Windows registry corruption or not properly configured system are some causes also.
If it was too high the PC would freeze,randomly freeze or hang, programs would crash.
Check Task Manager startup tab for too many running processes, check process tab and details tab. Did you update system drivers since upgrade to Windows 10 from PC manufacturer's web site ? Run a full scan for viruses and malware, not sure what you use.
Run System File checker at Admin command prompt, copy and paste, press enter, let it finish
sfc /scannow
