Acer with Win7 is acting very erratically. Opening a simple word processing program can take three or four minutes, or may not open at all. Am constantly getting a message that Firefox or OpenOffice or whatever is not responding. Cursor is bouncing allover the place or disappears altogether. I constantly get window saying the program isn't responding. The computer froze while writing this simple note and I had to do a recovery to get it back. And now can't save it. It can take five or six minutes for the computer to shut down. Day before yesterday, the computer would not start; got a black screen. Tried my Restore that I have on a stick. F2 wouldn't open. The next morning I got a window saying that Windows would repair the Start Up. That took a few minutes and I was pleased to get my desktop back. But Bill Gates lied to me again and I had the same situation the next day.
It's working now but things very slow. I tried the Windows Fix Up from the Control Panel but that didn't do anything. Computer is Acer Aspire One, about three years old.
Any ideas would be appreciated.
