Thanks for the answer and the comment, I'll explain
The computer works fine, but lacks a hardware update.
I want to have an NVMe M 2 as a boot device, but the motherboard does not have this possibility.
I have installed an SSD as a boot disk but it does not have the speed of the manufacturer, it is much lower. Run at the maximum speed allowed by the motherboard.
I bought a card to solve the problem, but the motherboard does not have a connection, I could not install it.
So I think the best way to upgrade is by changing the motherboard. I understand that I must also change the CPU and ram memory.
But I already have all the other components and I think they should work with the new motherboard.
I consider the case ventilation system to be very good, the power source is 750 W, I just changed it, and I already have the new devices but they don't run at the expected speed.
If I could just upgrade the motherboard with an NVMe M2 connection and put in SSDs that run at their manufacturer speed, that would be ideal for me.
Any recommendation?
