Hi there, you could also specify the exact model of your Asus so that we could better understand how bad things are and suggest if there’s something reasonable you can try in order to speed this up (unlikely).
Looks like you could be speaking of some model similar to X451/X551 series - there’ve been some poor modifications with N2815/N2830 Celeron CPU, supporting only max 4Gb of RAM. However, even in this case, you can still slightly improve it’s performance by replacing a slower hard drive (HDD) with a faster SSD.
