My daughter has a HP desktop that will not boot up. She allows her son to use it and since his usage, the computer no longer functions. I am thinking that the operating system has become corrupted in some way, either by virus, or any other error that affects Windows based PCs. She has allowed her anti-virus program to lapse. I am thinking that reformatting the hard drive and starting from scratch would resolve this problem. But, she has photos stored in the computer that she would like to retain. Is there a way to obtain and remove the photos from the hard drive before action is taken on the hard drive? I was also considering purchasing a harger HD which would eliminate reformatting.
