What can we do with the faulty older computers in garages and storage closets? Most can be restored to working order at minimal cost, delivering reliable value.
Don't trash them! Recycling computer hardware conserves natural resources, protects the environment, supports secondary IT deployments, and reduces both e-waste output and IT procurement costs.
Diagnose & Revive Old Desktop PCs With Confidence.
Perfect for students, hobbyists, and IT learners. Comes with step-by-step guides.
- There is no need to purchase new computers when running non-CPU and non-GPU-intensive applications.
- We can restore old PCs to working order for word processing, or deploy extra systems in home spaces like the kitchen for on-demand web browsing, or to watch webinars while doing housework or exercising.
- We can set up multi-PC networks to practice computer networking concepts and prepare for IT certifications.
- Older computers are ideal for hands-on practice and computer literacy learning for children.
Old computers give kids valuable hands-on computer learning experience. They are significantly cheaper than new systems, so there’s less financial risk if something breaks during practice.
Children can learn computer hardware by hands-on diagnostics using a PC diagnostic starter kit.
Getting an old PC up and running again is a fun, rewarding learning experience for kids — don’t you agree?
PC diagnostics is a systematic process; starting this training at a young age helps foster structured task management skills through hands-on practice.

The full-size diagnostic card is compatible with standard PCI slots on legacy desktop PC motherboards only – it does not work with PCIe slots.
Refer to the image above to confirm that your desktop motherboard features a standard white PCI slot for the full-size 4-digit PCI diagnostic card included in this kit.
Please take care to distinguish standard PCI slots from PCI Express (PCIe) slots:
1. Check the silkscreen labels printed along the edge of the expansion slot (as highlighted by the yellow circle and red markings in the image above).
2. Additionally, the keying notch (alignment pin position) differs between PCI and PCIe slots.
If you have any question, please ask, we will help. Please have your PC brand/model number or your motherboard model number ready. The motherboard model number is typically printed between expansion slots, or in the area adjacent to the CPU socket.
If your motherboard only includes PCIe slots and lacks a native PCI slot, check our store for the latest V8 PCIe USB POST diagnostic card kit for PCIe systems. Click the link below for full product details.
Always select the diagnostic kit matching your motherboard's expansion slot type to meet your troubleshooting requirements.
