Well my old computer the one I gave to my grandmother blue screened the other day again (with the Nod32 AntiVirus) so I knew it was not MSE causing it but my mother did not believe me and said to buy a license for her which now was not needed. Please mods don't delete this for mentioning the other antivirus program. I thought maybe because of the hard drive going bad because it blue screened last August and also use to lock up too so I bought a new Dell laptop in September. I decided to give my old PC to my grandmother in February and just get a new hard drive but now I see that it was a waste of money now that hard drives are so expensive. I will have to get hear a new computer because blue screens are just about impossible to fix and all she does on it is play Sol-suite and MahJong games so MSE was fine for her.
