Little background - 1155 socket i5-2400 with asrock h67m-ge board. I tried putting in a new mobo/cpu cooler. Had issues, mobo had bent pins and didn't work so I put the old mobo back in. Still didn't work so I put the old cooler back in (the noctua barely fit and I think it was screwing things up) and after a lot of random nonsense - wifi not working, pc not turning on with both hard drives in only 1, etc. I finally got it all back to normal. EXCEPT cpu usage is always at 100% according to task manager. pc is running fine, msi afterburner is saying usage is around 20% with netflix and chrome up which seems fine. What's up with task manager?
