Nothing starts after pressing power button, not even the bios beep
This is what happened to my friends comp a while ago.
He built his own PC and it worked fine for a 6 months, then his computer had random shutdowns. He replaced a SATA hard drive along with a new power supply, it worked for 2 months and started having the same random shutdowns. He stopped using it as frequent. A few weeks ago he tried to restart his comp it turns off after going into windows loading screen. i replaced the bios battery and reset the bios and now nothing loads. the power would be on and all the fans spinning and that's it. i took off his graphic card and tried using the on-board video card and still doesn't work. Any idea what's going on guys?
