Hi there,
this is quite old tech for a motherboard and without knowing a few more details it is going to be hard to offer any help.
please post back with the following information:
CPU/APU - Model
Graphics: On-board or dedicated GPU - If a dedicated GPU make & model
RAM: Speed an amount
Make and model(s) of SSD and any other storage devices.
There are a lot of things that can impact the speed of a system and it might take a bit of time to get to the bottom of the issue. The more information you can provide, the easier it will be to help.
