My uncle was asking me how to speed up his pc. I happened to be at his house so I went to go defrag his computer and clean cookies etc. It took about 10 minutes for the defragger to open. I was shocked. Not much I could do after that. A week later he called me saying he couldn't boot his computer. I thought that must be why his computer was so slow before. I checked it out. He apparently had some virus that had filled his hdd with porn, when I last saw it he had less than 30gb of space used. So I wiped it and reinstalled windows 7 for him. The computer is still so so stupidly slow. It is unusable in my opinion. Its a some gateway computer. Specs: i3 530 6gb ram 1tb hdd windows 7 Why oh why is his computer so slow even after a reinstall? I would suspect the hdd. I am pretty much stumped on this one.
