Blue screens are not normally bios issues. They are usually a bad driver or other hardware problem.You need to provide more info for us to help further, We need your Dell model number, OS version and any further issue on the blue screen like any reference to a program or the code .

That is a start. What about the OS and more blue screen info. when do they happen is another thing to supply

I will turn my laptop on and right away it will freeze or flash to the blue screen and shut itself down or restart.  I was told this could be a bios problem or overheating. I have since hooked up fans to it to cool it down but that hasn't solved the problem. Can anyone please help me.

my model is a Inspiron 1525.

My OS is windows vista.  The blue screen flashes so fast its hard to read but it usaully says something like this can occur if you have installed a new program and it is corrupted or missing files.  I haven't installed anything new in weeks so I didnt think that was it.  I can be only laptop anywhere from two - ten minutes and it does it everytime.  I have tried reinstalling all my programs and this didn't help any.

Ok here is how to stop that so you can capture the blue screen. Right click on the my computer icon and select properties.  in the window that opens select advance system properties. in the next window select the advanced tab. on the Start up an recovery line select the settings button. in the next window uncheck the box automatically restart.

Then the next time you get a blue screen it will stay there untill you hit a key..
