Ram is the easiest to upgrade. Go crucial.com to find what ram your computer needs. CPU upgrades and hard drives are harder to upgrade.
If upgrading hard drive to faster one, you need to buy new hard drive and install windows onto it and this not recommended for inexperienced users.
Upgrading ur cpu is also not recommended for novices. When upgrading cpu, u need to make sure the cpu is compatible with ur motherboard. if not gotta buy new motherboard and make sure ur hardware are compatible with the motherboard.
Therefore just upgrade the amount of ram. this usually can make ur computer faster and is simple. Just make sure u get the right ram. If not, wont make a difference and can damage ur pc.
If i want my computer to be hella fast, what do i need more: high GHz, high HD RPM, or high amount of RAM? which one would you recommend to upgrade first?
