should I try Norton Power Eraser??

I'm having issues with my computer that regular scans are not finding. In the last month or so, the blue screen of death has popped up at least 5 times. I'm thinking I should use the Power Eraser to do a deeper scan. But, I'm a little afraid of it. Will it remove anything I may need? Or does it ask me what to do with any problems it detects? I'm not savvy enough to know what I should do. Is it reversable if I make my computer run worse than it is now? Most of the time, all is smooth running. But, THAT'S when the blue screen appears! I DON'T KNOW WHAT I SHOULD DO! I don't want to do any further harm to this. 

PLEASE HELP ME TO UNDERSTAND THE PROS & CONS OF THIS POWER ERASER! OR IF I SHOULD EVEN TRY IT??

THANKS!

oh, I'm running firefox & norton 360
