Hi. Well just yesterday i started experiancing this : I kept getting white dots all over my screen, id alt tab into a game or whatever and they would go away, alt tab out and my screen postioning would be messed up (like half the side black with start menu where black starts) um, i got fed up and thought maybe i had a virus so i reformated - during reformat some letters (in the reformat) were purple, some where capitalized (like thAnk) etc. Well i got thru the reformat, but then my comp wouldnt load - it was go thru its normal thing (when stuff scrolls in begining) and then the screen would get a bunch of white lines and fade in to white, then fade into black. so i swapped HD and tried this again, same thing., can get thru the "boot process" but when windows screens ready to load it does this. What can i do? anyone have a clue whats wrong? i know its not a virus cause of reformats and swaps. Thanks!
