If you don’t have a great deal of cash but still want to boost your PC performance, what can you do? Well, it may not be obvious unless you’re familiar with all of the possible factors affecting your setup. Expensive upgrades are out of the question here, so I wondered if ChatGPT could suggest sensible recommendations for anyone who needs help making the most of what they have.

My question: What are five ways to boost PC performance for $50 or less?

ChatGPT’s response: If your budget is $50 or less, there are several ways to improve your PC’s performance without replacing major components. Here are five of the best options:

1. Replace the CPU thermal paste ($5–15)

• Fresh thermal paste can reduce CPU temperatures, especially on older systems.
• Lower temperatures help the CPU maintain higher boost clocks instead of throttling.

This is a useful response. If you suspect your CPU is not performing at its best, install a monitoring utility (I’d recommend HWinfo) and check the CPU sensor reports under “Thermal Throttling”. If you do have throttling, your CPU is actively preventing itself from overheating and being damaged. New, improved thermal paste on an older system could help dissipate more heat.

Removing and applying thermal paste is fairly straightforward. Recruit help if you’re not comfortable doing it, though, as this will require removing any CPU cooler you have. If you have an older prebuilt, you could reach out to the company you bought it from for some helpful advice on handling this. Also, you may want to investigate a new, better CPU cooler for your PC.

2. Improve airflow with case fans ($10–40)

• Adding or replacing case fans can lower CPU and GPU temperatures.
• Better cooling can improve sustained gaming and productivity performance while also reducing noise.

Indeed. The second side of the cooling coin, with the first being ‘replace the thermal paste’. A lot of modern prebuilt PCs come with a full complement of fans and (often) ample cooling. However, if you have a self-build, or you can identify opportunities to add fans for better airflow, it’s a good way to keep your CPU cooler – as are removing your PC from direct sunlight or radiators.

3. Install an SSD – if you still use a hard drive ($20–50)

• If your operating system is on a mechanical hard drive, moving it to a SATA SSD is one of the biggest performance upgrades available.
• You’ll notice much faster boot times, quicker application launches, and a more responsive system.

Yes, of course, an SATA or (newer) NVMe SSD is far faster than a hard disk drive (HDD). HDDs are still faairly okay for mass storage, but not for speedy performance. SSDs will absolutely load applications, games, and even your PC far faster. However, buying an SSD in 2026 isn’t cheap. Up to $50 is possible for a 256GB SSD, as I write. But that won’t store much data.

4. Clean the inside of your PC ($10–20 for compressed air if needed)

• Dust buildup restricts airflow and raises temperatures.
• Cleaning fans, heatsinks, and filters can restore cooling performance and reduce thermal throttling.

General computer hygiene can certainly help to keep your PC in good condition and performing well. Scheduling the cleaning of dust from filters and inside your PC is a good thing to do. However, compressed air needs to be handled correctly, and in the longer term it makes a lot of sense to invest in an electric duster. These are fairly inexpensive and can be used repeatedly.

5. Optimize your software (Free)

• Disable unnecessary startup programs.
• Remove unused applications.
• Update graphics drivers and chipset drivers.
• Enable your system’s appropriate power plan.
• Check that your memory is running at its rated speed (e.g., XMP/EXPO enabled, if supported).

A sensible-ish collection of options, with the cleanup factors being for PCs that have been progressively getting worse over time. Ideally, keeping unwanted programs off of your PC and keeping drivers up to date should be ongoing duties. However, Windows is fairly good at keeping drivers up to date, aside from those for your graphics card. So check those every couple of months if you can or if games are misbehaving.

For your power plan, you’d want the ‘balanced’ mode in most cases. ‘High performance’ locks your CPU to its highest boost clock and prevents your system from putting devices like hard drives into sleep states when they’re not being used. So you’re generating more heat, fan noise, and locking your system into full performance all the time. The ‘Balanced’ plan will scale your performance – and use less power too.

Overall, though, some solid suggestions from ChatGPT in this full list. Not bad, AI, not bad. Right, I’d better get my electric duster.
