Windows 7: How to determine process eating up CPU resources?

How to determine process eating up CPU resources?

Is there any way in Windows 7 to see what any particular processor core might be struggling with? Every time I Sleep my computer and wake it back up, Core 5 comes back at almost 100% utilization and I can't figure out what it's doing or why. It'll even be listed as 'Parked' and STILL be tapped out. I can't figure out how to correlate Core 5's business with what might be keeping it tied up. See screenshot attachaed of my cores/processes. It looks like 'System Interrupts' is the culprit, but it's such a vague and nebulous description it doesn't do me much good in troubleshooting.
Thanks!

I would use process explorer to get a bitter picture of what is being used. I would also follow the link in my sig to fill out your system specs for further help on your wake issues.

Thanks Malcom! I think I've actually ended up solving my stuck-process issue, and I figured I'd post what I did here in case anyone else encountered the same problem.

I used a free program, "LatencyMon", to narrow it down to a 'most likely' few device drivers. I attempted to update them all via Windows 7 (Device Manager -> device -> driver -> update driver -> search automatically), but all came back and said "The best driver is already installed". Well, I then used another free program that automatically checks and updates drivers as needed, "Driver Booster 4", and it came back and showed that I had 41(!) drivers that were either 'old' or 'very old', or terms to that effect. After updating all my drivers, the problem now seems to have disappeared. I find it very odd and quite disappointing that a free third-party application does a better job of keeping Windows drivers updated than Windows does, but whatever.
I appreciate the offer of help!

I'm glad your fixed.
Do you have a backup to a date before using ???

Code:
Driver Booster
IObit
www.iobit.com/driver-booster.php
The odds of needing 41 drivers updated all at the same time are slim to none.

I have absolutely 'ZERO' faith in anything by IOBits.

As much as I appreciate the guidance, does anyone have a suggestion for a better driver checker/installer than Drive Booster? It certainly *seems* to have worked where the Windows 7 driver update process did nothing. Yes, I have a backup from before I used the product but unless I see an actual issue it may cause me I won't be rolling back. What, specifically, are people's issues or problems with this company or program?

Yeah use Driver Cloud and post what it finds before installing anything.

Find your drivers. Analyze your PC and your blue screens.

Also update your specs so we can see what should even pertain to your build.

Task Manager is the obvious place to go in to and look for all the process eating up resoures.

Task manager is very limited and would sometimes only show the main process rather than a subprocess which could actually be what's eating up the CPU resources. Just saying.
