Hello, I bought an Acer Aspire 3680 from an internet dealer about 8 months ago. Here's my problem: When in the boot process every thing's fine until we get to the login password screen. At that point, my keyboard and mouse stop responding. Nothing works. It's like the keyboard and mouse are locked out. I tried booting in safe mode but that doesn't work either. Any ideas before I shoot it with a 12 gauge?
