It sounds like you could be missing a driver or two. Anything having ! or ? in there needs a different driver. I'd check the Acer web site for your model and make sure I had all the right ones. Two that come to mind are chipset and one that affects data transfers to and from your hard drive.
Acer laptop I3 processor would not accept updates also all previous updates disappeared tried microsoft fixit to no avail tried the reg fix but didnt work finally after reloading the op system has fixed that problem but now I am left with a very slow computer used msconfig stopped all programs loading on startup this didn't improve anything where do I go from there
