When your computer has a black screen and will not boot you have a computer problem that might be simple or serious. Having a black screen on your computer can be as. So I have finally managed to get the i58600K and all I can say is that it is blazingly fast and more importantly without any fuss. This CPU overclocked to 4. Ghz. Lots of people, including myself, are having big problems trying to update Windows 10 to the Fall Creators Update. We all get error message 0xc00000bb when trying to. Gryphon Z87 BIOS version 0801Intel Haswell i74770Windows 7 Pro, 64bitPulling my hair out here. Ive set this new computer up, but 19 time sout of 20 when I reboot. This update will see the death of the old email program Outlook Express, as well as the depreciation of the popular Paint application. As Microsoft told Gizmodo back. Example 2. The computer turns on and makes normal startup noises, the LED lights turn on but noting appears on the screen. First of all, take a closer look at the screen under bright light. Its possible the screen shows the image but its very faint. In this case youll have to troubleshoot the backlight failure. On the other hand, if the screen shows no image at all, test the laptop with an external monitor or TV connected to the VGA port or DVI port or HDMI port. You can toggle video output between internal and external modes by using Fn keys Fn and F4 keys simultaneously on HP laptops Fn and F5 keys on Toshiba laptops Fn and F7 keys on IBM laptops. Other laptops may use different key combinations. If the external monitor works fine but the internal screen has no image at all, the problem can be related to Poor connection between the video cable and screen or motherboard. Try reconnecting the video cable on both ends and check out if this helps. The screen failed. Replace it with a new one. The video cable failed. Replace it with a new one. The motherboard failed. If both, the internal and external monitors show no image, the problem can be related to Failed memory RAM. Failed motherboard. Try reconnecting the memory module, maybe its not making good connection with the slot. Try cleaning contacts on the memory module. Try moving the memory module into another slot. Try replacing the memory module with another one. If you have two modules installed you can try removing them one by one, its possible that one of the modules failed. Try moving modules from one slot to another. If changing or reseating memory doesnt help, you can try this Removing the battery, hard drive, DVD drive and other components you can easily access. Try turning on the laptop without these components installed. Its possible one of them failed and its preventing the entire computer from starting up properly. Also, try turning on the laptop with an external monitor while the video cable is unplugged from the motherboard. If external image appears after you disconnected the video cable, apparently there is something wrong with the cable. Replace it with a new one. If the computer is still dead, try removing other internal components wireless card, modem, keyboard, etc and test it with an external monitor after each removed part. The last step is testing the laptop as a barebone system. On this picture you see my final test. The motherboard has been removed from the base and I assembled a basic barebone system on my bench. The bare bone system includes 1. Motherboard like in most cases it has onboard graphics chip. CPU with the cooling module. Known good memory module. The power button board. Known good AC adapter. If the system still doesnt turn on, its either bad motherboard or failed CPU. If you computer shows garbled or distorted image, check out this post.
