I got laptop form a friend for repair, on start up blue screen appear and when I have booted from CD the HDD was empty which is strange since she have lots of date and suddenly the screen went blue, after I have formatted partition C and install new windows everything was correct expect the pc performance and use of internet, I swap 512MB 5300 555mhz DDR2 ram with 1 GB 4200 444mhz which I have found in my junk box, but there is still problem with the performance, when you start internet in iexplorer or firefox and you type in search engine or in tab bar the text appear with few seconds delay as you type, and even that website is loaded when you scroll its slow. I did not format partition D. That’s this mean that laptop have not enough ram for windows XP or is it virus or I need better Memory ram, I have installed Java and flash. As well updated Graphic card and have latest version of windows explorer and firefox as well I have enter msconfig and disable all apps that are not from windows and are not crucial to run os. Any though ? As well I have contacted my friend and she said that this issue happpened as well before the crash of widnows.
