My computer was running just fine. I then shut it down for about 30 minutes, try and turn it back on and it doesn't turn back on with 3 red and 4 white led blinks. I already tried to swap the ram back to the original, but that didn't help.

Here is the troubleshooting guide for that error page 83
"3.4 - The system board displays a power failure (crowbar)" Most likely place to start troubleshooting is the power supply.

I already tried 2 different power supplies. The thing that really confused me was that it was working just fine before i shut it down. I use to be able to keep power cycling it and it would turn on normally. Sorry for the wait.
