Heat can also cause your PC to slow down over time. If your PC can’t cool itself efficiently, it may throttle down your CPU or graphics hardware to operate safely, giving you reduced performance. Excessive heat can damage your PC’s hardware over time or cause it to unexpectedly shut down to prevent itself from suffering severe damage.
If you hear your PC’s internal fans whirring to maximum speed during light or moderate usage, it may be a sign that your system is overheating.
1. Bust the dust
Give your PC’s case a regular cleaning to prevent dust build-up.
While your computer is powered off and unplugged, open up its case and give it a spray with canned air to clean out that nasty dust clinging to fans and blocking vents. Depending on how long it’s been since you last cleaned your PC, you may find it surprisingly dusty!
You may also want to try cleaning out your laptop’s cooling fans, but opening up a laptop may be more difficult.
2. Replace the paste
Your computer’s CPU and GPU use a thermal compound to help dissipate heat. This compound sits between your both your CPU and your GPU and their respective heatsinks. The paste conducts heat from the heat-generating chip to the heatsink. The heatsink is then cooled by moving air pushed by a fan.
This is similar to how your car cools itself. If you imagine your your CPU or GPU as an engine and the heat sink as the radiator, the thermal paste would be the coolant.
The compound, like the coolant in your car, can deteriorate over time. This can cause problems cooling your CPU or GPU.
You can disassemble your GPU and replace its thermal paste or remove the heatsink from your CPU and replace the CPU’s thermal paste. You’ll want a thin, flat, uniform layer of paste.
Hardware upgrades can also give your PC a new lease on life. Of course, hardware upgrades aren’t always the right solution. If your PC is a decade old, you won’t be able to speed it up much with a hardware upgrade. You’d be better off buying a new PC entirely. With that in mind, here are the best bang-for-the-buck upgrades.
1. Replace your drives
The bottleneck in most PCs—that is, the slowest part of the PC that you find yourself waiting for most often—is the hard disk.
Solid-state drives are much faster than traditional magnetic hard drives, although they do offer less storage space per dollar. You can get a 120 GB SSD for $100, while you can get a 2 TB—that’s over 17 times more storage—magnetic hard drive for about the same price.
If your PC is only a few years old but it seems like the hard disk is the slowest part, you can probably boost its speed by upgrading it with a solid-state drive. You may even be able to upgrade your laptop with an SSD. Whatever you do, be sure to move your operating system and program files to the SSD.
2. Upgrade your Random Access Memory (RAM)
More RAM can help too, but only if your PC doesn’t have enough of it already.
RAM holds your PC’s working memory. If you have too little RAM, your PC will have to constantly read and write to the pagefile on its hard drive, slowing everything down. If you go this route, be sure you buy the correct type of RAM for your PC.
3. Upgrade your CPU or graphics card
Other upgrades are a bit more niche. If you’re a gamer and want to run games on higher graphical settings, you may want to upgrade your PC’s graphics card.
Bear in mind that your performance bottleneck may be your CPU: If your CPU isn’t fast enough, upgrading your graphics card may not help much.
CPU upgrades are possible, but Intel regularly introduces new socket formats, which means new CPUs may not fit in older motherboards. Also note that an Intel CPU won’t work in a motherboard with an AMD CPU socket, and vice versa. You may have to upgrade your motherboard as well, and at that point, you may just want to think about buying or building a new computer.
Your old PC hardware won’t last forever. New software will eventually become more and more demanding, and your old hardware will one day succumb to entropy and physically break down. Fortunately, some basic system maintenance can extend any PC’s usable life. Take care of your PC and it will keep you happy longer.
