Black Screen on boot? o.O
 
Hey guys,

when I boot up, it posts, windows loads, but then when it gets to the 'Select User' part, its a totally black screen!

I am however able to boot up into safe mode, which works perfectly, which is what I am doing now. I have ran Prime95 in safe mode now for about 5hours, just to make sure my pc is still performing the same, which it is. I have also ran AVG to check for virus' but it didn't find any.

What should I do? :/ :sad:

Thanks in advance :)

Which OS? maybe in safe mode Do you have Dual monitors it might be loading up the second monitor instead of the main desktop , I have had this happen way back when I used to run two monitors.
if none of those are the case then maybe uninstall the video drivers reboot and reinstall the Video drivers

could it be a boot sector error maybe? (along the lines of the MBR?) - Something to consider i suppose

Make sure your monitor is working properly before you start troubleshooting............:whistle:

Suggestion: check the configured screen resolution, maybe? Display drivers?

It could be that while you are loading windows it looks fine (low res screen) but then switches to a different frequency at the login screen (the configured display settings). If that is a frequency that your monitor cannot handle, you get a black screen.

I had this once on a flakey monitor; it would go black when the login screen showed up. I had to turn the monitor off/on then, and it would refresh and I could see the screen (very annoying). I ended up changing the display settings.

I don't know if in your safe mode you are using the same resolution. Try configuring the display driver with a lower resolution, a different refresh rate, etc...and rebooting into normal windows. Hope that helps.

It could be something wrong with the Display drivers. You could uninstall the display drivers (when in safe mode) and reinstall them from scratch.

if it was Linux I would say that it was definitely the freq but I am not sure which OS is running. I used to always run into the freq problem in Linux had to manually change it in the Xorg.conf

How many monitors do you have hooked up if you have two or more, maybe try and disable the other screens and have one in safe mode, i had a problem before when i had two monitors hooked up and one of them had a loose connection, it would show the logging into windows then go black so i unplugged one and it fixed it but if this doesn't work maybe back up all your stuff, and re-install windows or try other monitors.
