Hi all. I have a packard bell computer that re started on it's own, but it will not go past the start up screan , my mouse and keyboard will not work, i took it to the local pc repair shop and it worked ok when they plugged it in used his key board, he told me that if the key board stops working then the computer will not go any furthe than that page. I purchased a new microsoft wireless keyboard and mouse (old ones were cable) got it home plugged it all in, it worked ok then it did the same again. Computer turns on but won't go further than the packard bell start up screen with enter f1 in the botton lefthand corner. I dnt't know a lot about computers
