Once a computer component stops working we need to decide if we’re having it replaced, repaired, or just get by with a temporary fix. For the short run, repair or just getting by will nearly always be the cheapest solution. Replacement on the other hand will usually provide a better fix and an opportunity to even go for an upgrade. In fact, considering the rate at which the most technologies behind computer hardware have been evolving recently, unless you replace something soon after a purchase, you’ll most probably be getting an upgrade for your next replacement.
Below are 5 components of your computer which, if replaced (and generally upgraded), will provide excellent benefits, from enhanced user experience, additional compatibility, greater longevity to full system stability.

1. Power Supply: One of the most overlooked component of computer hardware is the [url=https://buyanypart.co.uk/search?query=PC%20power%20supply]power supply unit[/url] (PSU). Computer geeks often brag about their super-fast processors, cutting edge video cards, and massive gigs of RAM, but rarely about their great PSUs.
Sincerely, the power supply is the last thing you should hold back on when choosing components for your system. If a computer’s brain is its processor, its heart is the power supply. And having one that is worn out, underpowered, or just generally cheap can be a major cause of hardware failure.
Every computer’s power requirements differ, but a good minimum for a modern PC is 450 watts. Some systems, particularly those with several [url=https://buyanypart.co.uk/search?query=video%20card]high-end video cards[/url] or lots of additional cards and peripherals may require a PSU rated at 800 watts or more. Replacing a failing or inadequate power supply can make a previously unstable system stable.

2. Fans: Since computers have gotten more powerful over the last few decades, they have also gotten hotter. Instead of passively cooled Pentium 100, we now have fans on our massive CPU heatsinks, on our monstrous video cards, and on intake and outtake vents to our computer cases. All of these computer fans play significant roles by keeping our systems safely cooled, and we should ensure that they continue doing so. 

As one of the few moving parts in our PCs though, they are one of the most likely to actually break. When they break though, it’s likely to pass unnoticed or not cause much concern. Also, fans are cheap and easy to replace. It generally takes about 8 Pounds, 15 minutes, and a screwdriver to install a new one, so there’s really no good excuse for not doing so. 

3. Video Card: One of the most essential and priciest elements in the performance of your system and overall user experience; there are two major reasons to replace it should your old one bite the dust.
 First, video cards are one of the components that are being improved nearly every day. A two-year old video card simply cannot be as fast as a current one and won’t have the newest features (such as support for DirectX 12). Also, the [url=https://buyanypart.co.uk/search?query=video%20card]video card[/url] is the number one hardware stopgap as we migrate OS (operating system). Manufacturers just won’t provide compatible drivers for lots of their old video cards if their users migrate to higher OS since they want to sell newer video cards too. This means that many of us will have to replace our video cards whether they are broken or not, if we plan to upgrade.
