Wrong values in taskmanager after changing motherboards.

[ancienthardwarelives]

Hello, recently I switched out my MSI G31TM-P35 mobo with a Gigabyte GA-G31M-ES2C. After the swicth my I started experiencing longer boot times and laggy animations. I also noticed that taskmanager shows a lot of wrong values. For example when my cpu is pegged at 100% taskmanager only shows around 80% at around 2.8Ghz even though I have a 3GHz cpu (see picture 1 below).

I also found that it cant fully identify my RAM, it calls it "4GB Unkown" instead of "4GB DRR2 667" or something like that. It also says my RAM is clocked at 800Mhz although is running at 667Mhz (see picture 2 below).

I have tried:

-Fresh install of windows 10 64bit -installing all new drivers -changing to some leftover ram sticks

PC specs:
Gigabyte GA-G31M-ES2C
Core 2 Duo E8400 3Ghz
4GB DDR2 667Mhz PC5300U
320GB HDD
350W PSU
Windows 10 64bit
(GPU hasnt arrived yet, using iGPU)

You lucky getting win 10 to even run on the PC, Intel don't support the chipset anymore. LGA 775 was what my last PC had and I didn't even contemplate putting win 10 on.

new drivers when last OS board supports in win 7 isn't a lot to work with. - https://www.gigabyte.com/Motherboard/GA-G31M-ES2C-rev-2x#support-dl
