17 R4, blue screen error, messing up boot order

Hello

I have an Alienware 17 r4. It has been for quite sometimes getting the blue screen error. Its major error is "Critical Process Died" and sometimes "kernel exception storage" or "storage". When it first time happened it changed my boot order completely. Afterwards i have been having increase in frequency of blue screen errors. In bootingup it would stuck in alienware booting screen. After quite forced shutdown it would reach the desktop but after which it would stop and give BSOD. Then  it would check itself for any hardware problems and at the end with no prblem it suggests that this might be due to corrupt os image something.

After this it might give BSOD if i play or do light working with bunch of actions in a hurry like shutting a window opening another stoping a downloads or something.

I have reinstalling issue where it wont reset to fully clean disk drives and stuck at 33% only affecting my hard drive to be formated not ssd. I still did a reinstall but it has again started giving BSOD after clean working for a day.

I really need to know what is affecting my pc and which components or is it software related so i can fix it asap. Appreciate your help.
