Hi, Ive borrowed a friends laptop but noticed its extremely slow in starting up. I have unsintalled AVG which i think was causing issues, but sill think its having issues. Im trying to establish whether its hardware or software related but dont have a clue. Also If I try and i play sound the laptop is extremely choppy and, and the sounds seem to get stuck like a cd repeating itself.
