Have you ever turned on a computer that has been restarted? Do you think it was a virus? Well, in many cases it may or may not be. First off, there are many reasons to restart your computer. It was a virus, your computer will tell you that no operating system was found. Or, you will die on the blue screen. In the following steps, I will show you how to prevent your computer from being restarted from the logo page.
Honestly, you don't need a virus protection right now because you can't access the Windows operating system. I have repaired many computers with this situation and believe me, it is quite simple.
Check out the fans
When you turn on your computer, make sure the fan is running at the very beginning. If it is a virus that infects your computer, your fan screen will continue to run without any. Your fan is located on the back of the computer. That is at the power supply.
If your fan is still running, you will need to reinstall your Windows operating system. Please remember not to do this unless you read my next article, "How to save your files from an accessory PC".
Unplug the PC
If your fan is not running, this is good news now. You need to turn off all power from your computer. I recommend you unplug the power cord behind the PC. You need to open your PC
Dust on the CPU fan.
Another reason your computer may be shutting down is because the computer is overheating. The CPU does not get a lot of air flow when the computer is turned on and the PC temperature is higher when it goes to the operating system, so computers need fans. But is the PC raising the temperature? Well, its dust !!!
Another CPE fan with dust
It's time to clean a PC. Get your paper towel and q-tips. Simplify your magnetic strip, or if you have no magnetic strip, touch the power supply to your own ground from your electromagnetic shock.
Clean CPU fan
Get your q tips and dust off your CPU fan. The air does not pass through the CPU, so the computer shuts it off so that the computer does not catch fire. Clean every hole in the computer case, make sure its clear to let air in. Your CPU fan should look like the picture.
All dust off the computer case. Once done, turn off the computer and plug everything in again. Start your PC it should load.
If none of this works, you must open the computer case and make sure all the divers are plugged in securely. Many times a technician installs a new drive or RAM on your system and it is not installed properly. Your computer will not start. Make sure the RAMs in the PCI slot are nicely protected. Make sure that the 2 white side handles shown in the picture are inserted correctly into the RAM. Close your case and start your computer. That should work.
If that doesn't work, it could be your RAM or motherboard. You have to go buy a new motherboard or RAM. I recommend you take it to a technician to install the motherboard, but if you know how to install a new one, good for you. Remember to back up your data. Very important.
