I reset my dad's old PC and put in a gtx 950 and a x3450 in the place of an i3 530. When I booted it up, it took 30 minutes to get me to the desktop. After that everything was slow and took many minutes to open. The mouse stutters and the keyboard doesn't respond quickly. I'm pretty sure it's a driver issue but I have no clue how to fix it as even an ethernet connection doesn't work and I have no discs. It's a prebuilt HP Pavilion p6330f. I tried installing the nvidia drivers via USB but it didn't work and I have no clue how to get drivers for my motherboard and I don't know where to look. If you can please find the mobo drivers I will love you forever. Any help is appreciated. Thanks for reading.
