So heres the story. The computer has been working fine for several years. Last night I decide to plug in my tv to the desktop via dvi. It works fine and I dont have any problems. I get home today and try and turn the computer on and I dont get any video signal to either the tv or the normal monitor. Also 3 long beeps accompany start up, it sounds as though things boot but I dont get video or sound, but it sounds like the hard drives click now and then like normal and the fans all run fine. Ive swapped the first ram stick with one other and havent tried the rest yet and I have not changed the video card yet but plan to in the next 30 minutes as of writing this. Nothing looks physically damaged and I dont have any extra ram for this computer laying about since its a rambus so all I can do is swap the ram thats in it around and because I cant get video I cant run a test on the ram. Suggestions or help would be appreciated. Specifically what the 3 long beep codes mean, ive found a couple different versions of the code online and not sure which is correct. Also what might have caused the problem? plugging the tv in? thats the only thing I did different unless someone was messing around with it without my knowledge, or could it just be from years of wear or what?
