You're facing complex computer issues. What troubleshooting techniques should you master for the future?

Diagnosis has many layers, here's some of them, check if computer running or getting power if not check SMPS, Power Cable, Cable that are connectedto motherboard etc, if computer standby but No signal or BIOS not showing up, check RAM or Graphics Card, try clearing CMOS etc. If BIOS showing but Computers not booting further, check Hard-drive, Sata Cable or powering cable etc. If computer corrupted try restore or repair or clean install. If nework or any particular software or hardware not working properly, check for drivers are updated and firmware updates. These are some common issues but there are definitely more complex issues where motherboard, processor, RAM or other hardware can be damaged.

I will try to master all 6 techniques: 1.Basic Diagnosis 2.Error Codes 3.System Restore 4.Hardware Checks 5.Clean Installation 6.Networking Issues

une simple diagnostic est toujours la première chose a faire: * vérifier les cables. * vérifier alimentation. * ouvrir task manager pour voir une utilisation excessive de ram ou de cpu. * lancer un diagnostic avec le cmd . * entrer dans le mode sans echec pour voir si le probléme presiste.

Diagnostics If the computer is running really slow then the first thing you should do is optimize the computer by cleaning the temp files and turning off unnecessary start up apps. Running the system file checker could be useful towards repairing system files. If it's still running really slow, it will most likely be a failing hard drive. You can identify a failing hard drive with Crystaldiskinfo. The computer will always run terribly slow and have long wait times if the hard drive is failing. If you have lost your internet make sure it's only for that device to rule out your internet service provider. Disable system protection|Run a virus scan|System file Check| Reset your internet settings. Blue Screens are hardware/system issues.

I'd start here: Basic Diagnosis: Start by identifying the problem. Check error messages, system behaviour, and recent history. Error Codes: Note and research specific error codes that appear. They can provide clues about what's wrong. System Restore: Use this option to revert the system to a previous state when everything worked fine. Hardware Checks: Ensure the computer's physical components are properly connected and functioning correctly. Clean Installation: If all else fails, reinstalling the operating system can resolve persistent issues. Networking Issues: Check cables, connections, and network settings to troubleshoot internet or network problems.

Error codes obviously tell you there's a problem and where to look but in order to use them effectively, it's worth noting when the error occurs. For instance if the error occurs 45 mins to an hour after the device has been running, then you may have a temperature related issue. This could mean the device reporting the problem could be functional but the cooling is inadequate. One other thing to bear in mind with Error codes is if its a CAN error. CAN bus systems are in series so potentially any module before the one giving the error may be faulty.
