My computer has been having some problems. It would run loud. And then it started shutting itself off very weirdly. I'd be typing email or surfing the net and then it would just power down. Instantly. I did open the box and try to remove some dust. And the week before by friend formatted the drive using something called fdisk and then we reinstalled the software.
Any thoughts as to what's really wrong with my computer? Is it fried or will it start again?
