Upgraded Mobo and CPU, Having issues

[Dannz93]

Hello

So after a year or so I decided to upgrade my Gigabyte f2a55m-hd2 mobo and AMD x4 740k cpu.

My system before hand ran windows 10 no problems, but now when I boot up its very leggy and slow. It can take 15 mins before I can click things which themselves take there sweet time. I have had a blue screen error a couple time also and it's not using my GPU graphics but it seems on board graphics which my board hasn't got slots for.

Do I need to repair or fresh install windows again? It works fine in safe mode so I can't say for sure what's up.

PC Specs are:
MSI 970 gaming motherboard
AMD fx 8350 cpu
Sapphire dual x Radeon r9 280
Corsair vengeance 8gb 1600mhz
Corsair 500 psu
Seagate barracuda 1tb hdd

Thanks in advance

You should reinstall Windows when you change motherboards. It should work well once all the low level stuff (drivers, settings, etc) is out of the system

Do a complete format and re-installation of the OS. You changed Mobo's and CPU's so the OS (Windows 10, I'm assuming) is having a hard time figuring out all of the new components each time you boot the system.
