hi all, well heres the situation

i just built a pc for my little niece out of some old pc parts.. well ive ran into quite a few problems to start off the hd was failing so i replaced it and installed a clean version of xp pro

i installed all the drivers and even updated the onboard graphics drivers

now to my question..

i believe the onboard graphics are on their way out,, but i want advice

symptoms,, graphics seem gittery at times

some times upon opening folders or apps there becomes lines all over the screen

pc shuts off randomly upon installing some apps

pc shuts off every time while trying to install small games from http://www.reflexive.com/

pc shuts off even when trying to open the games,, even if i just use there folders from "program files"

games dont restart the pc when opening the games in 256 colors. compatability mode.

well thats about it,, do you think its the onboard graphics or could it be some other area i should look into..

thanks for any advice you can give..

well it seems ive located the issue,, its a bad memory stick.. go figure.. thanks any ways
