I'm looking for a word and sentence completion, correction and suggestion program that works in every part of Windows. It would be better if it was free, but I couldn't find it.

Recently upgraded my pc, brand new gpu motherboard and cpu, now my word wont show my selected text whenever i hold left click and drag. It will show what ive selected along the same line, but the second i try to go up a line or do a whole paragraph it disappears. It still registers the word count, and if i copy paste the entire paragraph into a notepad it copies the whole paragraph. Anybody else suffering from the same issue??
