Ok so i bought a HC Pavilion Entertainment PC 5 days ago, when i started using it i realised that I can use the pc without lagging for 10 minutes and then it really lags very bad. It stops lagging if i didn't use the pc for 2-3 minutes and the cycle goes on and starts lagging again after 10 minutes. It is so annoying and I also checked task manager and i found out the CPU usage is like 90% when it lags.
All programs like chrome, skype etc are necessary, is there any other way to stop lagging and reduce the CPU usage?
(Also no virus/protection software is installed on my PC)
Please somebody help me real fast, thanks!!
