hi i need steps on how to dissemble a pentium computer. i was wondering if anyone could give me a specific website because i looked in google but I don't know, I can't find what i want.

It has to be pentium and it can't be pentium 2 or three or others.

Pentium is a processor, not a computer. Please read:

Your computer may well have an Pentium Processor inside, but it probably has a brand name on it somewhere. If not it may be a custom job.

To disassemble a computer with a Pentium processor, the general steps are as follows:

1. Preparation: Make sure you have a clean, static-free work area and all the necessary tools, such as a screwdriver set, antistatic wrist strap, and thermal paste.
2. Power down: Shut down the computer properly and unplug it from the power source.
3. Remove external components: Disconnect any peripheral devices, such as monitors, keyboards, and mice, and set them aside.
4. Open the case: Depending on the type of computer case you have, you may need to remove screws or slide off panels to gain access to the internal components. Consult the user manual or search for specific guides based on your computer model.
5. Ground yourself: To protect sensitive components from static electricity, wear an antistatic wrist strap and attach it to a grounded object or touch a metal part of the case before proceeding.
6. Disconnect cables: Carefully unplug all cables connected to the various components inside the computer, such as power cables, SATA cables, and data cables.
7. Remove expansion cards: If applicable, unscrew and remove any expansion cards, such as graphics cards or sound cards, by gently pushing down on the release latch and sliding the card out of its slot.
8. Remove the power supply: Unscrew the power supply from the case and disconnect all power cables attached to the motherboard, storage drives, and other components. Carefully lift the power supply out of the case.
9. Remove storage drives: Unscrew and disconnect any storage drives, such as hard drives or SSDs, by removing their mounting brackets or sleds and disconnecting the data and power cables.
10. Remove the memory: If necessary, remove the memory modules by pressing down on the retention clips at each end and sliding the modules out of their slots.
11. Remove the CPU cooler: Carefully unclip or unscrew the CPU cooler from the motherboard. This may involve detaching a fan or heatsink.
12. Remove the CPU: Unlock the CPU socket lever and gently lift the CPU out of its socket. Be cautious not to touch the gold contact pins or the top surface of the CPU.
13. Clean and reapply thermal paste: If you plan on reusing the CPU or replacing the CPU cooler, clean off the old thermal paste from both the CPU and the cooler using isopropyl alcohol and then apply a fresh layer of thermal paste before reattaching the cooler.
14. Reassemble or dispose: If you are planning to recycle or dispose of the components, separate them into the appropriate categories (e.g., metal, plastic) for responsible disposal. Otherwise, follow the steps in reverse order to reassemble the computer.

While I cannot provide a specific website for disassembling a computer with a Pentium processor, there are numerous resources available online with step-by-step guides, video tutorials, and forums where you can find information specific to your computer model. Some popular websites that offer computer disassembly guides include iFixit (www.ifixit.com) and Tom's Hardware (www.tomshardware.com). Additionally, searching for your specific computer model along with the term "disassembly guide" can often yield useful results.
