How-to fix computer hardware; symptoms and troubleshooting help – computer hardware repair tip

Computers are a work of science.  Since all computers require the same basic hardware and connections to be operational, any computer issues are “Elementary, my Dear Watson.”  If Sherlock Holmes were alive today, he would probably be a computer expert since all computers are built similar to cars to other machines that require the elementary, basic core to be up and running.  Thus, if the computer breaks down or crashes, it is pretty logical to determine where the issue lies and then the computer fix is straight-forward.

Well, if you still think computer repairs are not “elementary,” we’ve helped you out by providing the below hardware symptoms that are typical of PC computer issues, along with the specific hardware to check for fixing or replacing to get your computer working again.

  1. Symptom: No sound, no lights when turning on -> Check: power supply, motherboard, CPU
  2. Symptom: Continuous beeps when turning on -> Check: keyboard, video card, memory, motherboard
  3. Symptom: Screen is blank upon boot up -> Check: power on monitor, video card connection
  4. Symptom: Operating system doesn’t load -> Check: hard drive, memory, motherboard, CPU
  5. Symptom: Screeching noise -> Check: power supply, CPU, hard drive, floppy drive, speakers
  6. Symptom: Shuts off by itself -> Check: BIOS power features, power supply, fans, dust
  7. Symptom: Operating system freezes -> Check: Windows; probably not a hardware issue

These technical support scenarios should help you out during your next PC crash.
