Did you backup? If so, you should be able to find your drivers on it. If not, it would be a good idea to find a driver disc for your make & model of laptop. On it, there will be a lot of diagnostic tools, too. If you can't obtain one from HP, you may be able to find one on eBay for a decent price ($5 to $10). That's were I got mine from, and they were helpful to me.
