New high-spec PC running slow

[Kieran Vyas]

I have just built my own PC (i7 5820k, GTX 970, 32GB memory) and quite often it suddenly becomes slow and unresponsive. I have ran checks on my HDD's and SSD and they say there is nothing wrong, also my GPU, CPU and memory never runs more than around 10%. Restarting the computer fixes the issue.

How can I troubleshoot this problem?

Below is a screenshot of my task manager whilst the PC is slow.

EDIT: Just figured out the problem only occurs after waking my PC from sleep mode. ???/

Don't let the PC sleep

Get the Task Mgr again but sort by CPU descending. I use both sleep and hibernate multiple times a day on Win/7 Pro 64bit without any problems - - you should be able to also.

I suspect this could be related to your Power Management options. Is your PC set to Maximum Performance(actual wording may be slightly different)?
