PC Upgrade Guide
Make a slow system run better — SSDs, RAM, CPU, GPU, power, cooling and compatibility tips.
Common problem: Older PCs usually have
mechanical hard drives (HDDs). They are mechanical, wear
out, and are the most likely part to fail.
The fastest, most noticeable upgrade for many systems is
replacing an HDD with a Solid State Drive (SSD). SSDs have
no moving parts, offer much faster boot and load times, and
are more durable.
What is a PC upgrade?
A PC upgrade is replacing or adding hardware to improve performance or capability — examples include a faster CPU, more RAM, a larger or faster drive (SSD), or a better GPU. Upgrades extend the life of an existing system without buying a new one.

Cloning your HDD to an SSD — quick checklist
- Pick an SSD with enough capacity (or larger) than your current drive.
- Get a SATA/USB adapter or install the SSD inside the case.
- Use cloning software (Macrium Reflect Free, Clonezilla, vendor tools) to clone the drive image to the SSD.
- Set the SSD as the primary boot device in BIOS/UEFI and verify it boots.
- After successful boot, optionally wipe the old HDD for reuse or backup.
