Power supply problem
I'm having problems that I'm pretty sure are related to my power
supply. I installed a new dvd burner in my system. The system booted up fine. It recognized the DVD player and installed it. It told me that I had to reboot the system to complete the installation. I rebooted it and it worked fine for about 5 minutes. After about 5 minutes after reboot the system shut off just like I unplugged the computer. I was standing near the computer but not actually using it while this happened. The computer has not booted since. If you push the on switch, absolutely nothing happens. I have unpluged and repluged the computer into several different plugs. I bought a new more powerful power supply and installed it but the system is still dead. There is a light on the motherboard and there is a light which goes on and off as I turn the computer on and off with the dsl plug. So it appears that I am getting power. I returned the new power supply and got another. And the exact same thing happens with the 3rd power supply. I had the exact same systems happened when I got the computer 2 years ago. The original power supply failed, I installed a second, when I brought it to a shop they installed a third power supply and told me that the power supply I purchased was bad. This all started when I installed a new DVD burner. Since the system booted, installed the DVD player and then rebooted sucessfully, I doubt that there was any problems with the DVD installation. I could have overloaded the old power supply. Is there anything else I can check? My motherboard is an ASUS A7n8x-e Deluxe |
