First of all I just want to say hi and thanx to everyone in advance. Now, a friend of mine approached me in need of help with her machine. I don't the spec. of the computer but I can say that the computer was bought over her dad's friend who is giving a good deal. Now I can say that right from the start it sound like bad hardware but I still want to look into it the best I can. I'm no specialist when it comes to computers but I have fixed mine and my girlfriends in few occasions and I want to help my friend. Here are the problems. She said that this problem started out of the sudden and it gotten worse over time. USB ports (all of them. front and the rear) started messing up images from camera, usb flashs and so on. Also any .exe .rar file would come corrupted if transfered from usb. The other problem is dvd drive. This problem also got worse over time. First she simply couldn't read few dvds. Month passed and now that dvd drive can't read dvds at all. It can only read regular cds. The last problem is simply win xp being goofie from time to time. One other guy said that she has a nasty virus but that guy really doesn't know anything about computers. I'm not saying it's not a virus but she never got online with that computer and she doesn't load all sorts off junk there so I doubt that she picked up a nasty virus. I was told the the hard drive was once formated and a fresh copy of xp was installed but the problems were still there. I need any advices how to address to this problem. I'll probably check the rams, hardware itself, viruses and so on but I'm not proficient at spotting the problem right away so I need few pointers, what to keep my eye on and what to test first and so on. Also she has an anti virus installed there. I think it's avast but it was never updated since she has no internet. How can I fix that? That would be all for now.
