DV4621I
AMD A9-9425, Radeon R5, 5 computer Cores 2C+3G
16 RAM
OS Version 22H2
Build 19045.4291
The machine took 1:45 to boot and everything was correspondingly slow. I ran WhySoSlow and CPU activity often hits 100% when the machine is doing nothing.
So far:
* Fixed too many hard page faults
* Updated drivers
* Defragged disk
* Looked for runaway processes
* Checked for virus and rootkits
Also high are kernel and app responsiveness but I can't find the cause. Any suggestions?
Thanks - rev
Have you checked Task Manager to see which processes are using the CPU?
You can also try booting a live Linux disc or flash drive to see if you get the same issue. That might reveal whether it is a hardware or software issue.
Yes, I checked Task Manager for CPU and memory load but I couldn't find anything. CPU doesn't stay in the red, it's a brief peak but happens 4 or 5 times per minute and something somewhere must account for it. I'm out of my depth with other OS's. Even displaying a jpeg takes too long, I get a frame, some churning and finally the image appears.
Maybe Noah owned this laptop or NASA used it to go to the moon... Thanks
OK, laptop. That is helpful information. Laptops can have heat issues that desktop computers usually do not suffer from. Dust and debris can clog the relatively small ventilation openings, resulting in heat issues and CPU throttling. Check for that first. Fans can fail also. Try SpeedFan or similar software to check CPU temperatures.
Then, use Task Manager to view the CPU usage, with the highest usage processes set to be on the top of the list. Watch what happens as you perform actions. This might be easier if you can connect an external monitor so you can see the Task Manager window and whatever else you are working on.
If the same process is using the most CPU cycles, you have your answer. If the high CPU usage cycles through various processes, then something else may be going on, possibly with hardware throttling.
Check the S.M.A.R.T. statistics for the hard drive also, in case of retries on read/write operations. Run a memory test as well.
As previously suggested, try a live Linux OS to see if the same thing happens there.
Check for antimalware software using excessive CPU cycles.
I haven't totally solved it but I got the boot time down to about 40 seconds (HDD) from over two minutes by tinkering ith the paging file. I got the number of paging file operations down to 40 (still high) from over 4,000!
* Delete the paging file
* Reboot
* Recreate the paging file
* Set to user defined size similaar to what it was on auto.
That made such a huge difference the guy was happy.
