Laggy PC

[ChrisD69]

I've just fitted a new motherboard and CPU, an I7 10700k and a an Asus ROG Strix z490 e. Seems fine, but strangely it lags when opening programs, but is particularly bad at browsers it takes at least 30 s to open chrome or Edge.
I've been a bit lazy in not doing a reinstall of the OS. Is this punishment from the PC Gods? Anyone else encountered this problem

Thanks. I thought that might be the case. Just being lazy. Hate reinstalling everything. On a side note, is it really worth upgrading my boot drive to a pcie ssd? I'm using a sata ssd right now

I updated all the drivers including the chipset when I upgraded the components. But I done think I adjusted the bios much and definitely not the sata settings. Thanks
