Do you get sound? Could simply be a codec issue
soyo kt600 dragon plus v2.0We need your specs so we know what to look for. Please do list your power supply brand name and watts.
i did clear the CMOS, it did not work. i shut it down one day and the next time i tried it it did not come up. the fan and heatsink is connected and the molex connector is hooked up. and the fans on everything do work and if i plug in the hard drive and the dvd player they do get power.Did you try just one stick of ram (check your board manual for the proper slot for 1 stick)?
Does everything run except your video, or does it shut down?
Do you have the square molex plug connected to the motherboard? (some older boards don't require one, don't know about yours)
Do you have the heatsink fan connected to the motherboard?
Has it worked and just quit or are you just trying to get a dead one going?
Are you certain that the CPU is seated down tightly?
Try clearing the CMOS and see if it comes up that way?
Post back and we will keep trying. Actually the thing that bothers me is that you say it does not beep when memory is out of the board. Normally, that means a dead motherboard, but you say you have replaced that. Call me puzzled, but not giving up yet.
