So turn on computer looks like everything might be posting but black screen on monitor and the mother board says d6 error. Take out memory one at time and try nothing. Take out graphics card and put back in nothing. Pull out battery and re try and nothing. Monitor connects to lab top no problem. Leave it for next alone. Try to run next day for hell of it works. Works great for two days but I never powered down. Well last night I powered down and I am back to d6 error. Any suggestions?
