BIOS Problem.
What you are about to read will probably be a big ball of clutter, so bare with me.
I've been having problems with my BIOS ever since my laptop fan went bad on me.
I bought a new fan and right after that my computer would go into the BIOS and shut down mid way. If i got lucky enough it would start up after about 20 tries. I figured it was my fan so i took my laptop, and my sisters, (shhhhh) we have the same laptops and took them apart, i swapped the fans. First i started her laptop and hers started up fine. I tried to start mine up and now instead of shutting down midway in the BIOS it either does one of 2 things. The first thing it may do it show the very first part of the BIOS where it shows a little loading bar, then the screen will go black, then restart that process again.
The second thing it will do is it goes past the first little loading screen and it will go to a all black screen with blinking underscore. Now it will do either of 2 more things from here, it will either just sit and hang here or it will stay there for about 30 seconds then continue to boot up regularly. Once from here i don't have any troubles what so ever.
theres like a 70% chance it will go into the loop and 30 percent chance it will make it past there. At the black screen with the blinking underscore its like a 50% 50% chance. It's just very annoying and it can take like 5 minutes just to make it through the BIOS.
I have a dell inspiron 1521 with BIOS version A06.
Now, i really hope that made since.
