I found one and I followed the instructions and it said to type "chkdsk /r" and I ran disk check at next start. So it took about 2 hours to do so, then my computer seemed to start normally. but the colors were all messed up.
I looked on the apperance tab when you right click on the desktop to change the resolution/color stuff, and the resolution was set at the lowest and the color was set at 4-bit.
I tried to change it but nothing happened, and I rebooted but nothing changed.
I know its not a hardware problem because the windows logo that appears at the start looked the same as it always did.
I need some serious help if anyone could give some advice that would be greatly appreciated.
