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

The GTX5XX cards get very hot. Try to add a 3rd party cooler to the GPU.

Probably a good idea. Thanks.

This seems to have been an issue with my video card. I noticed the temp was high when doing nothing (79c) so I changed to a single display instead of dual and the temp dropped to around 50c in a few minutes. I haven't had this issue since-not even when playing games. Gtx 570 by the way. Maybe it's on it's way out.

don't open the kernel.etl. Open the DPC_interrupt.etl. Also enable the stack column and load the debug symbols.

Ok I think this is correct. There was no "stack" column option that I could find.

Hi,

I'm having the same issue with ACPI.sys. It makes games that usually run smoothly, stutter like crazy. Any ideas are appreciated. Thanks.
