I have had several issues with my computer. I paid to have it was I presume was a XP repair after a system restore went bad - not icons, start menu or taskbar. Now I'm am getting crashes now and then, but was has me stumped is the screen freezing, i.e. the web page or a game will just go distorted and nothing I do will infreeze it. I have to turn off the power and restart.
I have used device manager and there are no exclamation marks beside anything and all devices say they are working properly. I am considering paying to start from fresh as I have saved all important documents and pictures. Any ideas?
