[How to get the cause of high CPU usage by DPC / Interrupt]

have you renamed the kernel.etl to DPC_interrupt? You must run the 2nd command and give me this file.

From your current trace I can see that Google Chrome causes high HDD usage and this causes ATAport.sys Interrupts. Install the latest SATA drivers, look if your laptop supports running AHCI instead of IDE and check the HDD with chkdsk.

Yes, I did. I thought they were the same, apologies

I'll do it again and pm you the link. Thanks!
