Actually, the power button can do more than just turn the machine on and off. In fact, it’s possible to bypass the power button completely and turn the PC on and off with a different method. 

Before you try any of these other methods, you should check to make sure that the power button itself is working correctly. To do this, you’ll need to open up your PC and take a look at the power led motherboard. There should be a couple of pins near the power button that are connected to a switch. When you press the power button, these pins are supposed to be disconnected from each other.

This means removing them from their sockets and putting them back in. Often, this is all it takes to get the system up and running again.

If reseating the memories doesn’t work, you may need to replace them. You can buy new memory from most computer stores or online retailers. Be sure to match the type of memory your PC requires (DDR2, DDR3, etc). Also, make sure you get the right amount of memory for your PC. Most PCs require between 1 and 4GB of memory.

GPU might be causing the issue

If you just installed a new GPU, there’s a good chance that’s the root of your PC not turning on. Graphics cards draw a lot of power, and if your PSU can’t handle the load, it might not turn on at all. Try to turn on your PC without the GPU installed and see if it boots up. If it does, then you know the issue is with your graphics card.
