My fan has become really LOUD. So, I thought its about time to clean the inside of my computer and the fan. But what I did was, I opened up the fan case using a magnetic screwdriver (Idiot Me). I did not touch any of circuits and actual hardware with the screwdriver. I did it this morning and every things seems fine except that firefox is ACTING up. Unto the question: I was wondering am I likely to see any damage done to my computer later on?

Thank youThe connection between Firefox and your magnetic screwdriver should  be practically non-existant.

What kind of problems do you have with Firefox?I KNOW that there wasn't going to be connection to firefox, but I was just wondering would the magnetic screwdriver do anything to actual MOTHERBOARD, graphics CARD etc. I was wondering maybe if I would come across hardware problem from the magnets in the future, because my computer seems alright, but has only been a few hours after I used the screwdriver?

Thank you
There are magnets inside a pc case......power supply unit and cpu fan........
