Not sure what drivers to be installed.Welcome to the forums, newcomer!
Have you tried reinstalling your drivers? Mind sharing what you're interpreting as a driver issue? We all could use a lot more info from your end. Please list the specs to your build like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Oh okay.The RAM limitation is probably because you have a 32-bit version of Windows 10 installed.
H61 chipset depending on motherboard/CPU can support 4GB to 8GB of RAM I think.
