The failure of each device in the computer may be accompanied by corresponding problems during startup and operation. If you want to fix your computer yourself or just find out the reason for the malfunction, you must carefully check all the connections and watch it start up.
Instructions
Step 1
Check how the computer reacts to pressing the power button. If after it the computer does not perform any operations and does not even try to start, the problem most likely lies in the power supply, which supplies energy to the rest of the PC. Check carefully that all cables are connected and connected to the mains, try plugging the power cord into a different outlet. If the computer still does not start, then you need to replace the power supply.
Step 2
If the power supply is working and its fan is spinning, but the computer still refuses to start, it is likely that your motherboard is broken. It can be called the most expensive element in computer hardware. Replacing the board should be done in accordance with your processor model and the RAM you have installed. All this data can be found in the documentation for the computer.
Step 3
Open the side cover of the computer and check all the ribbon cable connections to the motherboard. Each wire must be firmly fixed in the correct slot or connected to the appropriate adapter.
Step 4
Remove the RAM brackets by gently sliding the special latches and pulling the cards out of the slot. Clean them from possible dust, and then reinstall them. Connect the power cable to your computer and press the power button. If the computer starts up, but freezes on the very first screen or makes any sounds, this means that your RAM has deteriorated and you need to purchase new strips.
Step 5
If the monitor displays image distortion and color stripes, your video card is broken. The video card is easy to replace - just open the case, take out the old video card and install the new card in its place.
Step 6
If you cannot identify the malfunction of the computer on your own, call a specialist at home or take the computer yourself to a specialized service center.
