How to troubleshoot black screen bootup?



When I turn on my PC it begins to boot up OK but just after the Windows screen loads (the one with the moving bar when windows is loading) the screen just blanks out, the computer is obviously still working as the windows log on sound eminates from the computer and the computer sounds like it is working.

I am sure it is a graphics card problem but apart from buying a new one is there anything i can do before being ripped off by the shop that sold it to me!!

Thanks in advance.

Unfortunately, there can be many different reasons why the black screen of death appears on login screen Here are some suggestions that have helped me when dealing with this horror story Your problem could be related to your video/monitors refresh rate.. Depending on the age/quality of your monitor you can run between 60hz and 75hz I would recommend that you boot into safe mode and go to display settings.. then choose advanced Then set the refresh rate to 60hz This should fix your problem If this doesn’t fix your problem, try removing and reseting the card, check all cables from monitor to card are securely fixed, remove the driver files for the card, use the windows generic vga drivers to see if the problem is definitely related to your drivers, get the latest bios, and drivers for your card and motherboard, and last but not least press F8 during startup and select use vga mode Good luck!!
