you installed all the drivers for the mobo?
does it run normal in safe mode?
you can try a bios update too.
Did you ensure that the high CPU usage is not due to svchost ?

Also try turning off your MS 'automatic updates', then reboot.   Manually select Windows updates, install the appropriate ones, then turn on automatic updates once again.  Reboot.  

If unresolved, see if there's anything appropriate here >
Since rebuilting the PC, have you been using the internet?  
If yes, and unless you are absolutely sure the machine is clean, may i suggest you run a few scanners such as Malwarebytes.  
Recommend downloading, then updating Malwarebytes' Anti-Malware:
When updated, reboot into Safe Mode by selecting F8 at bootup & run a scan.

Tutorial available, if you require >

Also, the Kaspersky free online virus scanner:

Newly released Acronis True Image 2019

One other thought ... another cause of sluggishness could be your HD ... if still unresolved, you may wish to try the appropriate diagnostic here for a HD test >

"Hard Drive Diagnostics Tools and Utilities":
If you check in 'Task Manager' Which process is taking up all the resources?
remember to check 'Show processes from all users'.

Thanks for all your advice.
I have done all the regular troubleshooting, example: test HDD, Ram, scanned for virus but still no indication what might be causing the slowness.
Checked Task manager and one of svchost image was using up the CPU, checked what services was running against it but still no indication of its abnormalities.

IHP will change motherboard, will see if that fixes the problem
Anyways, thanks for all your help people
