100% CPU usage -the same old problem but a little weird

[confused11]

Hello to anybody who responds,
I am really anxious to solve this problem. The thing is after I reboot my laptop( usually after hibernating, so not really a reboot) the laptop runs quite fast and I can play videos normally. Also, the CPU usage is about 3 or 4% only. But after a lapse of four or five minutes, the computer becomes way slow and the CPU usage become 100% and when I try to play videos, they are so slow that I see images instead of a video.
I have tried scanning for viruses, spyware etc. nothing really seemed to help.
I know this is an age old issue and there are a lot of forums regarding it but my case is a bit different. So, I would appreciate if anybody would like to help me.
Thanks beforehand.

Hello and welcome to Techspot.

Try turning off Windows automatic updates and see if that helps at all.

Hello and welcome to TechSpot :wave: ! Click ctrl + alt + del and then go to the processes tab of the Task Manager. Look at the bottom and look for a number of processes that you have (I.E. Processes: 32). Tell us this number .

thanks for the help but I tried turning off the automatic upadates and it didn't help. I could use something else.
The number of processes is 30. also, most of the CPU is consumed by taskmg.exe when I open the taskmanager and when I open the process explorer, most of the CPU is consumed by process explorer. Seems like the program I open takes up all of the memory.
Thanks again.
