It skips here and there and can barely do two things at once. I got a crap cleaner which didn't do much.. the hard drive is almost full too, all in all I think I got one that isn't really suited to my needs. Anyway, I was thinking about formatting my hard drive and reinstalling Windows, but I can't find my disc (I'm at uni and the disc should be at home but the only ones my sister can find are drivers and stuff) - if I get someone else's will I be able to use it? Also, for after I've finished, I need new anti-virus software because mine has expired and was rubiss anyway. We can get Sophos free from uni - is that good enough? One more thing, my graphics card probs isn't too great but I only play oldish games anyway but I might progress to something more demanding later... is it worth paying for extra storage and graphics card and stuff for a computer that isn't that good anyway? I just can't really afford a new one. Any thoughts would be appreciated a lot
