I have a dell optiplex 790 and it has 4gb of ddr3 ram at 1600mhz and it wont boot. But it gives me 1 and 3 light. The cpu is a i3 2100. Is the ram bad or is the frequency to high on the ram?
There are a lot of possibilities that could have happened, but most likely the power supply is dead or one of your parts died. I recommend building a new PC instead of messing with an old one however.
