11 Reasons Why You Should Not Buy Used PC Parts

Why You Should Not Buy Used PC Parts

When you are getting a second-hand PC part, the quality of the parts depends on its previous usage.

You may get some terrific surprises skulking within it.

It may be some contagious software, corrupt HDD, ghosting monitors, not compatible PSU, faulty cables, overheated batteries, etc.

Let us dig deep into some problems which may persist in the used PC parts and why in the first place you should not buy them.

1. Overclocking

If you are buying a used CPU then you make sure that it has not been overclocked during its previous tenure.

Generally, in the ad listings, it does not show whether it is overclocked or not, make sure you contact the seller and get verified on this point.

The same thing goes with RAM, generally, these are safe to reuse but sometimes RAMs are too overclocked or overheated.

So, if you have a chance to communicate with the seller then you can put forward this query.

2. Ghosting 

When you buy a used Monitor, you might have issues with the displays.

With time the liquid crystal display tends to age resulting in some common issues like dead pixels, geometric distortion, color fading, burn, and even ghosting. All these will be visually very disturbing.

Thus, before you make the final call, make sure you see the pictures of the monitor turned on.

In that way, you can check the monitor output and even the input devices.

3. Keyloggers & Crypto Mining 

When you buy a used PC make sure you have formatted everything and check whether there is any sort of malicious threats persisting like a keyloggers program which is generally meant to relay all the details to the previous owner as you type in anything.

These can lead to some potential risks if you are operating sensitive financial websites.

Every detail of your internet browsing will be monitored by the previous owner.

Another issue is crypto mining which is done by malicious software. The processor is being compromised and the information generated is all used for generating money.

So, when you buy a used GPU or CPU make sure it’s perfectly formatted and not “acting slow”.

4. Breakage

Used PC parts like keyboards, and mice are generally safe to reuse but there are breakage issues.

You can check the pictures carefully before buying these items.

Otherwise, you may have a problematic experience with the dead key buttons or sticky keys which can ruin your experience.

This generally happens when the parts are rigorously used and it is very old which makes them defective as a second hand.

5. Compatibility 

Compatibility is a big issue when you are buying used parts.

For example, if you are buying a used motherboard that is not compatible with your PC or the used PSU is not compatible with the power requirement or other necessary parts.

Sometimes this also happens when you are buying used RAM or processor parts.

6. Heatsinks, Jumpers, Batteries & Capacitor Failure

When you are buying an old motherboard then make sure you check out the heatsinks, jumpers, batteries, and even the capacitors.

If any of these parts fail then the motherboard will not work accordingly.

So before making the final call make sure that all these parts are not overused or laying in an extremely subpar situation.

If the motherboard is fully in perfect order, then only you should make the final call for purchase.

7. Mechanical Problems

Hard drives have very delicate magnetic platters which are easily susceptible to breakage thus causing mechanical problems.

This can lead to the death of the HDD at any given moment. SSD to be honest is not susceptible to such mechanical issues.

8. Deleted Malicious Files

Even though the hard drive is empty or not having any deleted files still some of the previous files can be like torrent movies, malicious virus-affected files, and more can persist.

These virus-affected files are sometimes very hard to remove and become resilient to the antivirus.

These files can be restored at any time even though they are completely deleted from the disk.

Thus, when you are buying the used disk make sure that you are not having these along with it.

You can simply ask the seller to get you a fully formatted disk so that you do not face any underlying software issues.

9. Power Issues 

When you are buying a used PSU then you can certainly have a risk of power issues, and compatibility issues, which can kill other parts or even catch fire.

The PSU when used for years generally sheds its life span, capacitors become budging and sometimes it does not get compatible with the board.

You can see almost similar issues when you are buying used batteries for laptops.

10. No Warranty, No Guarantee, Short Life Span 

This goes without saying that used parts don’t come with any guarantee or warranty.

That means the life span of all the used parts will be shorter. These used parts can die on the next day of your usage.

So don’t buy if the parts don’t come with a refund policy.

11. Age Limit

You should not buy a used part of a PC that is more than 3 years old. This is like Moore’s Law – the rule of thumb in the industry.

Cables, noisy fans, CPU, USB connections and even the PSU tend to lose their power to work faster.

But if you are looking for some random parts which are like RAM, Motherboard, and Hard Disk these can keep on with their age.

Questions & Answers:

What PC Parts Can You Reuse?

Certain parts can be reused for a long time like RAM, GPU, and CPU. But if the age of these parts is more than 3 years old then you should not expect a higher life span while reusing.

Can RAM Be Reused?

Of course, it can be reused if the used RAM perfectly fits into the new machines as per requirement, & the motherboard specifications and sockets are matching. RAM can be resold or recycled as a valuable PC part.

Can You Reuse a Motherboard?

Motherboards can be reused as it is considered one of the reliable parts of the whole CPU. If the compatibility matches then it can certainly be reused. You can use it again and again till it loses its value.


After reading this post it won’t be justified to think that you can’t buy or reuse any old PC parts, rather it is advised that you should check all the loopholes, and features that are necessary to represent these parts are working in good condition.

Another thing, you must check out the return policy while buying these used parts otherwise your money may go in vain the next day.
