Problems with Hoster audio and graphics and MP3's

[inthelimelight]

I purchased the ruggedized laptop a little over a year ago with the hoster already installed. From time to time I was having problems with the graphics/too slow or too fast - it seems like it was corrected after some of the updates- I was upgraded to 4.6- skipped and upgraded 4.8- currently I am still experiencing audio and graphic issues.- I have 2 gb ram- but the computer is clearing having problems- even when I look up another song- or try to upload while someone is singing- I have done all of the windows updates and went through the other changes that were recommended- still cannot seem to fiquire out what the problem is- I have about 7200 kma and about 2000 at the most of mp3's on the hard drive- any help is much appreciated.
