ok here goes to the best of my descriptive powers. my computer scree is to light, and the graphics are missing. I must have changed something and now I cannot seem to correct it. its like its missing where to click example if i am on a page i regularly visit i know where the places are or i guess, if i place the cursor over that invisible point the hand indicates that i can click. is this making sense? the pages are not vibrant and are blank in places i have a hp 6400 and i am using a usb stick wireless but it does the same thing when wired at work. thanks please walk me through the steps to correct.
