Jalan Besar and the streets around Sim Lim Tower have traded in electronics for decades, and a lot of second-hand PC hardware still changes hands here and at online-marketplace meet-ups nearby. Used parts are good value, but only when they work. Our shop at Bugis Street #CFL A08 is about ten minutes on foot from Jalan Besar MRT.
We refurbish desktops for a living, so testing used hardware is what we do every day. This page covers what goes wrong with used PCs and graphics cards, how to check one yourself before paying, and what a proper test costs.

What Goes Wrong with Used PC Hardware
Most second-hand faults are invisible until the hardware is put under load.
- Graphics cards worn by mining. An ex-mining GPU has usually run flat out for months. Fans and thermal pads wear first.
- Dried thermal paste and tired fans. The PC works at the seller’s desk for two minutes, then overheats in its first game at home.
- Drives near the end of their life. A hard drive with bad sectors or a heavily worn SSD still boots, until it does not.
- Cheap or ageing power supplies. The one part sellers rarely mention, and the one that can damage everything else.
- Parts that do not match the listing. Less memory than advertised, or a slower graphics card with a similar name.
- Software left behind. An unactivated copy of Windows, the previous owner’s accounts, or worse.
Signs a Used PC or Graphics Card Has Problems
- Coloured dots, lines or flicker appear once a game has been running for a while.
- The graphics card climbs past 85°C within minutes.
- A fan rattles, grinds or does not spin.
- The PC restarts on its own under load.
- Windows shows less memory or a different graphics card than the advert promised.
- The seller will not let you see it running a game.
How to Check a Used PC Before You Pay
Six checks you can do at a meet-up, in about fifteen minutes.
- See it start from cold. Never buy a PC you have not watched boot.
- Confirm the specs. Open Task Manager and check the processor, memory, drive and graphics card under Performance.
- Run it hard for ten minutes. A game or a free benchmark shows faults that the desktop never will.
- Listen. Clicking drives and grinding fans are easy to hear in a quiet room.
- Ask about the power supply. A known brand is a good sign. No label at all is a bad one.
- Ask for a receipt. Proof of purchase tells you the real age and whether any warranty is left.
What not to do: do not judge a PC on a few seconds at the desktop. Most faults in used hardware only show after several minutes under load.

Used Hardware Testing Costs
We confirm the price before starting, and tell you plainly what we find.
| Service | Price | Usual turnaround |
| Graphics card stress test and mining-wear check | From $60 | 1–3 days |
| Full health check on a used PC | Quote on request | 1–3 days |
| Clean, new thermal paste and fan service | From $40 | Often same day |
| Clean Windows 11 install on a second-hand PC | From $50 | Often same day |
A second-hand PC should always get a clean Windows install, because you cannot know what the previous owner left on it. If the test finds a fault we can fix, such as a worn fan or dried paste, we quote for that too.
Buying Used Without the Gamble
The risk in used hardware is not the age. It is not knowing its condition.
A private sale gives you a low price and no comeback. A tested refurbished PC costs a little more and removes the guesswork: it has already been stress-tested, cleaned and re-pasted, and it comes with a warranty. Our article on how we test every refurbished PC lists exactly what is checked.
If you would rather skip the meet-up altogether, you can try a refurbished gaming PC or office PC in our shop before you pay. Our second hand PC page explains the difference between refurbished and simply used.
Why Jalan Besar Buyers Get Hardware Checked Here

Every desktop we sell has been through the same checks, so we know where second-hand parts hide their faults.
Tested under load
The card or PC is run hard for long enough to expose heat and stability problems.
A plain verdict
You are told whether to keep it, return it, or fix it, with the cost of the fix.
Faults fixed on the spot
