    When I start my computer, it doesn't connect to the screen... The screen only goes into powersaving mode, wich it does when it doesn't connect to the PC... The one and only Niklas Ulvinge aka IDK

      Do you have a 2nd monitor/pc available? If so switching screens will show if hte problem is hte monitor or the PC. If not, do your PC give the normal beep(the on boot beep is an errorcode) when you turn it on? If it does the problem's your monitor, if not your PC. If it's your PC, we need to know it's model and how it's beeping differently to diagnose the problem.

        I take it this same screen and graphics card have worked together before? You'll have to forgive me for asking a few questions before I can say anything else. Does the machine actually turn on and post? You should hear one short beep on startup. If you hear any other number of beeps look here[^] if you hear "no beeps" indicating no POST operation occurs take it to a shop, or look here.[^] outside of that, you can check to make sure the VGA cable is connected tight (a loose connection can decide to move enough to stop connection just by time and gravity). Make sure you have the right VGA cable connected (some monitors have more than one input). Without more information on what is happening durint POST I can't help much. If it is the video, and you have a friend who lets you open up machines, you can swap video cards. If your computer boots normally on his card, and his computer does not show video, you know the problem is with the graphics card and can replace it (thank him with a beer/soda as per his preference and head off to the store). The easiest way to troubleshoot failed technology is with spare parts, making it more difficult for the average person. With some more details on what the computer is doing, can you pop the case open (preferably without damage) and peek to make sure the video card is plugged in, CPU fan starts turning (and GPU fan if appropriate). Any northbridge cooling that is on the motherboard also, basically if it has a fan, make sure it is turning. If not, that's a strong indication of where a problem started, though it may not end there. _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

          Yes your right, it's bios error, it won't beep at all when I start it I've been mixing a little with some harddrives and cd drives... But that can't be the problem, couse bios would start anyway... I hear everything spin up, but then I don't know what happends... The one and only Niklas Ulvinge aka IDK

            Thanks for your reply. Read my other post... I didn't think of the possibility of bios errors... The one and only Niklas Ulvinge aka IDK

              If it's not beeping the problem is probably something other than the bios. A failing power supply (bringing some power but not enough), or dead cpu would be more likely. If you have a multimeter you can check the former. Stick the probes into both a spare drive connector and the one on the mobo (a loose connection, or failing mobo parts could make the voltage levels different here than on a drive connector). Black to Red should be 5V, Black to Yellow 12V. A deviation of +-5% is within accepted bounds, more than that could be the problem.

                OK, I don't got a multimeter... I think my dad got one, but he's :zzz: now. I'll have to do it tomorrow... The one and only Niklas Ulvinge aka IDK
