Please help me! I bought not so long ago a custom PC, pre-built by owner on Craigslist only a few hours before this post. I turned it on for the 1st time and everything was okay. Just wanted to see what would happen if I were to restart it, and obviously it correctly restarted. Now I went on to try to install a whole bunch of Drivers from a CD (or DVD) that I believe came with the motherboard (was inside CD drive, and was same brand as the motherboard) since there was no network adapter for Ethernet, and when that finished I went to Windows Update and just clicked on "Restart Now." It did its thing and shut down, and as it tried to turn on by its self (all fans were running and all part were working) just literally 3 seconds later it just turned off. Then it tried turning on then 3 sec, off. And its stuck in this loop, so I have to remove the power cable to the PSU. Can't even get to Boot screen or see anything on the monitor. What did I do wrong, what can I do? How did this happen if it work just a few hours ago? Tried removing GPU, disconnecting CD drive and Hard drive. Switching RAM, trying with one RAM. Removing System and CPU fan. IDK HELP!
