What is wrong with my laptop!!!!?

When i turn on the laptop, the screen starts form the fujitsu page and then it moves on to the loading windows. But after the windows load, it immediately turn itself into a blue screen with words. Un fortunately, the screen quickly turn back to the starting point which is the fujitsu start up page before i can even read what was in it. And when it go back to the fujitsu start up page, the whole cycle repeats itself again... Sometimes after the windows load, the disk cleanup process starts. But most of the time after the windows load it would just go to a greyish page that have options like safe mode, safe mode with networking, safe mode with command prompt, last good configuration and start windows normally. I have tried everything!!! But it still doesnt work there was once when i tried the safe mode and deleted stuff that are unneccessary and was able to use the laptop again but only after using once the laptop has it problem again and now I cant do my work!!! I seriouly need advice!

Blue Screen of Death? Back up all your data if you can in safe mode and reformat. Tough break there

It sounds like your Operating System is corrupted. If this process is happening on a daily basis, let me suggest to you to perform a "clean reinstallation" of your Operating System by using your Recovery Discs. Place the recovery disc into your cd or dvd drive and turn off your computer. Close the drive and then turn on your computer again. It will automatically read the recovery disc in the drive and perform the clean installation. Hopefully, this will solve your problem. If the problem persists, it seems to me like there is something wrong with your motherboard. If this is the case, therefore, you need to replace your motherboard.
